Accounting Policies [Abstract]  
Summary of Significant Accounting Policies Summary of Significant Accounting Policies
(a)Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K filed with the SEC on March 1, 2019 (“Annual Report”).
The condensed consolidated balance sheet as of December 31, 2018, included herein, was derived from the audited financial statements as of that date, but may not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2019 or any future period.
(b)Principles of Consolidation
The condensed consolidated financial statements include the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated.
(c)Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates are used for, but not limited to, revenue allowances and returns; recoverability of long-lived and intangible assets; capitalization and useful life of the Company’s capitalized internal-use software development costs; fair value of acquired intangible assets and goodwill; accruals and contingencies. Estimates are based on historical experience and on various assumptions that the Company believes are reasonable under current circumstances. However, future events are subject to change and best estimates and judgments may require further adjustments; therefore, actual results could differ materially from those estimates. Management periodically evaluates such estimates and they are adjusted prospectively based upon such periodic evaluation.
(d)Concentration of Credit Risk
Financial instruments that potentially expose the Company to a concentration of credit risk consist primarily of cash, cash equivalents, marketable securities, restricted cash and accounts receivable. The Company maintains cash, cash equivalents, marketable securities and restricted cash with financial institutions that management believes are financially sound and have minimal credit risk exposure although the balances will exceed insured limits.
The Company sells its services to a wide variety of customers. If the financial condition or results of operations of any significant customers deteriorate substantially, operating results could be adversely affected. To reduce credit risk, management performs ongoing credit evaluations of the financial condition of significant customers. The Company does not require collateral from its credit customers and maintains reserves for estimated credit losses on customer accounts when considered necessary. Actual credit losses may differ from the Company’s estimates. During the three and six months ended June 30, 2019 and 2018, respectively, there was no customer organization that accounted for more than 10% of the Company’s total revenue.
As of June 30, 2019, and December 31, 2018, no customer organization represented more than 10% of the Company’s gross accounts receivable.
(e)Deferred Revenue and Customer Deposits

Deferred revenue is recorded when cash payments are received in advance of future usage on non-cancelable contracts. Customer refundable prepayments are recorded as customer deposits. During the three and six months ended June 30, 2019, the Company recognized $4.7 million and $15.4 million of revenue, respectively, and during the three and six months ended June 30, 2018, the Company recognized $3.6 million and $7.2 million of revenue, respectively, that was included in the deferred revenue and customer deposits balance as of the beginning of the year.
(f)Deferred Sales Commissions

The Company records an asset for the incremental costs of obtaining a contract with a customer, for example, sales commissions that are earned upon execution of contracts. The Company uses the portfolio of data method to determine the estimated period of benefit of capitalized commissions which is determined to be five years. Amortization expense related to these capitalized costs related to initial contracts, upsells and renewals, is recognized on a straight line basis over the estimated period of benefit of the capitalized commissions. Total net capitalized costs as of June 30, 2019, and December 31, 2018, were $17.5 million and $9.4 million, respectively, and are included in prepaid expenses and other current and long‑term assets in the accompanying condensed consolidated balance sheets. Amortization of these assets was $0.9 million and $1.6 million in the three and six months ended June 30, 2019, respectively, and $0.3 million and $0.5 million in the three and six months ended June 30, 2018, respectively, and is included in sales and marketing expense in the accompanying condensed consolidated statements of operations.
(g)     Recently Adopted Accounting Guidance

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, "Leases (Topic 842)", which was further clarified in July 2018 by ASU 2018‑10, “Codification Improvements to Topic 842, Leases”, and ASU 2018‑11, “Leases-Targeted Improvements”. ASU 2018-10 provides narrow amendments to clarify how to apply certain aspects of the new lease standard. ASU 2018-11 addresses implementation issues related to the new lease standard. The standard is effective for interim and annual reporting periods beginning after December 15, 2018. Under the new standard, lessees are required to recognize in the balance sheet the right-of-use ("ROU") assets and lease liabilities that arise from operating leases. The Company adopted the standard using the optional alternative method on a prospective basis with an effective date as of the beginning of the Company’s fiscal year, January 1, 2019, and applied it to the operating leases that existed on that date. Prior year comparative financial information was not recast under the new standard and continues to be presented under ASC 840. The Company elected to utilize the package of practical expedients available for expired or existing contracts which allowed the Company to carryforward historical assessments of (a) whether contracts are or contain leases, (b) lease classification, and (c) initial direct costs. The Company elected the use of hindsight practical expedient in determining the lease term and assessing the likelihood that lease renewal, termination or purchase option will be exercised. The Company also elected to apply the short-term lease exception for all leases. Under the short-term lease exception, the Company will not recognize ROU assets or lease liabilities for leases that, at the acquisition date, have a remaining lease term of 12 months or less.

As a result of implementing this guidance, the Company recognized a $123.5 million net operating ROU asset and a $132.0 million operating lease liability in its condensed consolidated balance sheet as of January 1, 2019. The ROU asset was presented net of deferred rent of $9.0 million as of January 1, 2019, in the accompanying condensed consolidated balance sheet
and as a change within operating cash flows. In addition, on February 1, 2019, the Company acquired through its business combination with SendGrid approximately $33.7 million in operating ROU assets, $32.6 million in operating lease liability, $14.2 million in finance ROU assets and $13.6 million in finance lease liability.

The Company measured the lease liability at the present value of the future lease payments as of January 1, 2019. The Company used its incremental borrowing rate to discount the lease payments. The Company derived the discount rate, adjusted for differences in the term and payment patterns, from the information available at the adoption date. The right-of-use asset is valued at the amount of the lease liability adjusted for the remaining December 31, 2018, balance of unamortized lease incentives, prepaid rent and deferred rent. The lease liability is subsequently measured at the present value of unpaid future lease payments as of the reporting date with a corresponding adjustment to the right-of-use asset. Absent a lease modification, the Company will continue to utilize the January 1, 2019, incremental borrowing rate.

The Company recognizes lease costs on a straight-line basis and presents these costs as operating expenses within the consolidated statements of operations and comprehensive loss. The Company presents lease payments within the cash flows from operations within the consolidated statements of cash flows.

The financial results for the three and six months ended June 30, 2019, are presented under the new standard, while the comparative periods presented are not adjusted and continue to be reported in accordance with the Company’s historical accounting policy.
 
See Note 5, “Right-of-use Assets and Lease Liabilities” for further information.
 
In March 2019, the FASB issued ASU 2019-01, “Codification Improvements” to Leases (Topic 842). This pronouncement did not have a material impact on the Company's financial statements.

In August 2018, the FASB issued ASU 2018‑13, “Fair Value Measurement (Topic 820) Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement”. The amendments under ASU 2018‑13 remove, add and modify certain disclosure requirements on fair value measurements in ASC 820. The amendments are effective for interim and annual periods beginning after December 15, 2019. The Company early adopted this guidance effective April 1, 2019. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

In July 2018, the FASB issued ASU 2018-09, "Codification Improvements ", which does not prescribe any new accounting guidance, but instead makes minor improvements and clarifications of several topics. Certain updates are applicable immediately while others provide for a transition period to adopt as part of the next fiscal year beginning after December 15, 2018. The Company adopted this guidance effective April 1, 2019. The adoptions of this guidance did not have a material impact on the Company's consolidated financial statements.

In January 2017, the FASB issued ASU 2017‑04, “Simplifying the Test for Goodwill Impairment”, which removes the second step of the goodwill impairment test that requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This guidance is effective prospectively for interim and annual reporting periods beginning after December 15, 2019. The Company early adopted this guidance effective April 1, 2019. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

(h)    Recently Issued Accounting Guidance, Not yet Adopted
In August 2018, the FASB issued ASU 2018‑15, “Intangibles—Goodwill and Other—Internal‑Use Software (Subtopic 350‑40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract”. This standard aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal‑use software. The standard is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements.
In June 2016, the FASB issued ASU 2016‑13, “Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments”, which changes the impairment model for most financial assets. The new model uses a forward‑looking expected loss method, which will generally result in earlier recognition of allowances for losses. In November 2018, the FASB issued ASU 2018‑19, “Codification Improvements to Topic 326, Financial Instruments—Credit
Losses”, which clarifies that receivables arising from operating leases are not within the scope of Topic 326, Financial Instruments—Credit Losses. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. In April 2019, the FASB issued ASU 2019-04, "Codification  Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments," which clarifies treatment of certain credit losses. In May 2019, the FASB issued ASU 2019-05, "Financial Instruments — Credit Losses (Topic 326): Targeted Transition Relief", which permits an entity, upon adoption of ASU 2016-13, to irrevocably elect the fair value option (on an instrument-by-instrument basis) for eligible financial assets measured at amortized cost basis. These ASUs are effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted. The Company is evaluating the impact of this guidance on its consolidated financial statements

As the Company views its marketable securities as available to support current operations, it has classified all available for sale securities as short-term. As of June 30, 2019, and December 31, 2018, for fixed income securities that were in unrealized loss positions, the Company has determined that (i) it does not have the intent to sell any of these investments, and (ii) it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. In addition, as of June 30, 2019, and December 31, 2018, the Company anticipates that it will recover the entire amortized cost basis of such fixed income securities and has determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the three and six months ended June 30, 2019 and 2018.
Interest earned on marketable securities was $2.6 million and $4.1 million in the three and six months ended June 30, 2019, respectively, and $0.7 million and $1.4 million in the three and six months ended June 30, 2018, respectively. The interest is recorded as other expense, net, in the accompanying condensed consolidated statements of operations.

The Company enters into reverse securities repurchase agreements, primarily for short-term investments with maturities of 90 days or less. As of June 30, 2019, and December 31, 2018, the Company was party to reverse repurchase agreements totaling $75.0 million and $35.0 million, respectively, which were reported in cash and equivalents in the accompanying condensed consolidated balance sheets. Under these reverse securities repurchase agreements, the Company typically lends available cash at a specified rate of interest and holds U.S. government securities as collateral during the term of the agreement. Collateral value is in excess of the amounts loaned under these agreements.
In May 2019, the Company made a strategic investment of $5.0 million into a privately held debt security in which the Company does not have a controlling interest or significant influence. The security and the bifurcated embedded derivatives are recorded at fair value in other long-term assets in the accompanying condensed consolidated balance sheet. Changes in fair value of the host contract will be recorded in the accumulated other comprehensive income in the Company's consolidated balance sheet, and changes in fair value of the bifurcated derivatives will be recorded in the consolidated statement of operations. The Company classifies its privately held debt security as a Level 3 investment within the fair value hierarchy based on the nature of the fair value inputs. No impairment was recognized for the three months ended June 30, 2019.
As of June 30, 2019, and December 31, 2018, the fair value of the 0.25% convertible senior notes due 2023 (the “Notes”), as further described in Note 9 below, was approximately $1,116.2 million and $743.4 million, respectively. The fair value of the Notes is determined based on the closing price on the last trading day of the reporting period and is classified as a Level 2 security within the fair value hierarchy.
As of June 30, 2019, the note payable assumed in the SendGrid acquisition, as further described in Note 9 below, is recorded at its carrying amount, which approximates its fair value based on the proximity of its effective interest rate to the current market rates. The note payable is classified as a Level 2 instrument within the fair value hierarchy.

The Company determines if an arrangement is a lease at inception. The Company presents the operating leases in long-term assets and current and long-term liabilities. Finance lease assets are included in property and equipment, net, and
finance lease liabilities are presented in current and long-term liabilities in the accompanying condensed consolidated balance sheet as of June 30, 2019.
Right-of-use ("ROU") assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not generally provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company’s lease agreements may have lease and non-lease components, which the Company generally accounts for as a single lease component. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term, and variable payments are recognized in the period they are incurred. The Company’s lease agreements do not contain any residual value guarantees. Leases with an initial term of 12 months or less are not recorded on the balance sheet.
The Company has entered into various operating lease agreements for data centers and office space, and various financing leases agreements for data center and office equipment and furniture.
As of June 30, 2019, the Company had 19 leased properties, with remaining lease terms of one year to 10 years, some of which include options to extend the leases for up to five years.

Fiscal 2019 Acquisitions
Capio, Inc.
In June 2019, the Company acquired all outstanding shares of Capio, Inc. ("Capio"), a developer and provider of an automatic speech recognition technology based in Sunnyvale, California, for a total purchase price of $14.4 million, paid in cash, of which $4.0 million was withheld by the Company for a period of 18 months and an additional $0.2 million was withheld for certain tax liabilities to be settled in the near term. These amounts are recorded in the long-term and short-term liabilities, respectively, in the accompanying condensed consolidated balance sheet as of June 30, 2019.

Additionally, the Company granted 43,556 restricted stock units of the Company's Class A common stock to former Capio stockholders that had a value of $5.9 million and are subject to vesting over a period of three years. The Company is recording stock-based compensation expense as the shares vest.

The acquisition was accounted for as a business combination and the total purchase price was allocated to the net tangible and intangible assets and liabilities based on their fair values on the acquisition date and the excess was recorded as goodwill. The acquired entity's results of operations have been included in the consolidated financial statements of the Company from the date of acquisition.

(2) The goodwill is primarily attributable to the future cash flows to be realized from the acquired technology. The goodwill is not deductible for U.S. tax purposes.
The Company acquired a net deferred tax liability of $0.8 million in this business combination that is included in the long-term liabilities in the accompanying condensed consolidated balance sheet.
The estimated fair value of the intangible assets acquired was determined by the Company, and the Company considered and relied in part upon a valuation report of a third-party expert. The Company used an income approach to estimate the fair values of the identifiable intangible assets.
The Company incurred costs related to this acquisition of $0.8 million that were expensed as incurred and recorded in general and administrative expenses in the accompanying condensed consolidated statement of operation.
Pro forma results of operations for this acquisition are not presented as the financial impact to the Company's consolidated financial statements is immaterial.

SendGrid, Inc.
In February 2019, the Company acquired all outstanding shares of SendGrid, Inc. ("SendGrid"), the leading email API platform, by issuing 23.6 million shares of its Class A common stock with a total value of $2,658.9 million . The Company also assumed all of the outstanding stock options and restricted stock units of SendGrid as converted into stock options and restricted stock units, respectively, of the Company based on the conversion ratio provided in the Agreement and Plan of Merger and Reorganization, as amended (the "Merger Agreement").
The acquisition added additional products and services to the Company's offerings for its customers. With these additional products, the Company now offers an Email API and Marketing Campaigns product leveraging the Email API. The acquisition has also added new customers, new employees, technology and intellectual property assets.
The acquisition was accounted for as a business combination and the total purchase price was allocated to the net tangible and intangible assets and liabilities based on their fair values on the acquisition date and the excess was recorded as goodwill. The values assigned to the assets acquired and liabilities assumed are based on preliminary estimates of fair value available as of the date of this Quarterly Report on Form 10-Q and may be adjusted during the measurement period of up to 12 months from the date of acquisition as further information becomes available. In the three months ended June 30, 2019, the Company recorded a measurement period adjustment of $7.1 million to reduce its preliminary purchase price related to the value of the pre-combination services reflected in the assumed equity awards, and $7.0 million to reallocate value between the acquired intangible assets and goodwill. Both adjustments were recorded as a result of further refinement of the assumptions used in the process of valuation of these assets.
As of June 30, 2019, the primary areas that are still not finalized due to information that may become available and may result in further changes in the values assigned to various assets and liabilities include purchase consideration and purchase price, including related tax impact, and valuation of tangible and intangible assets.
The adjusted purchase price of $2,843.4 million reflects the $2,658.9 million fair value of 23.6 million shares of the Company's Class A common stock transferred as consideration for all outstanding shares of SendGrid, and the $184.5 million fair value of the pre-combination services of SendGrid employees reflected in the equity awards assumed by the Company on the acquisition date.
The fair value of the 23.6 million shares transferred as consideration was determined on the basis of the closing market price of the Company's Class A common stock on the acquisition date. The fair value of the equity awards was determined (a) for options, by using a Black-Scholes option pricing model with the applicable assumptions as of the acquisition date, and (b) for restricted stock units, by using the closing market price of the Company's Class A common stock on the acquisition date.
The unvested stock awards assumed on the acquisition date will continue to vest as the SendGrid employees provide services in the post acquisition period. The fair value of these awards will be recorded as share-based compensation expense over the respective vesting period of each award.
The purchase price components, as adjusted, are summarized in the following table (in thousands):

Developed technology consists of software products and domain knowledge around email delivery developed by SendGrid, which enables the delivery of email reliably and at scale. Customer relationships consists of contracts with platform users that purchase SendGrid’s products and services that carry distinct value. Trade names represent the Company’s right to the SendGrid trade names and associated design, as it exists as of the acquisition closing date.
The goodwill is primarily attributable to the future cash flows to be realized from the acquired platform technology, acquired intangibles, assembled workforce and operational synergies. Goodwill is not deductible for tax purposes.
The estimated fair value of the intangible assets acquired was determined by the Company, and the Company considered or relied in part upon a valuation report of a third‑party expert. The Company used an income approach to estimate the fair values of the developed technology, an incremental income approach to estimate the value of the customer relationships and a relief from royalty method to estimate the fair value of the trade name.

Net tangible assets were valued at their respective carrying amounts as of the acquisition date, as the Company believes that these amounts approximate their current fair values.
The acquired entity's results of operations were included in the Company's condensed consolidated financial statements from the date of acquisition, February 1, 2019. For the three and six months ended June 30, 2019, SendGrid contributed net operating revenue of $45.9 million and $74.5 million, respectively, which is reflected in the accompanying condensed consolidated statement of operations. Due to the integrated nature of the Company's operations, the Company believes that it is not practicable to separately identify earnings of SendGrid on a stand-alone basis.
During the three and six months ended June 30, 2019, the Company incurred costs related to this acquisition of $0.5 million and $12.9 million, respectively, that were expensed as incurred and recorded in general and administrative expenses in the accompanying condensed consolidated statement of operations.
The following pro forma condensed combined financial information gives effect to the acquisition of SendGrid as if it were consummated on January 1, 2018 (the beginning of the comparable prior reporting period), and includes pro forma adjustments related to the amortization of acquired intangible assets, share-based compensation expense and direct and incremental transaction costs reflected in the historical financial statements. Specifically, the following adjustments were made:     
For the three and six months ended June 30, 2019, the Company's and SendGrid's direct and incremental transaction costs of $0.5 million and $39.9 million, respectively, are excluded from pro forma condensed combined net loss.
For the three and six months ended June 30, 2018, the Company's direct and incremental transaction costs of $0.5 million and $12.9 million, respectively, are included in the pro forma condensed combined net loss.
In the three months ended June 30, 2019, the pro forma condensed combined net loss includes an increase to the valuation allowance of $0.6 million. In the six months ended June 30, 2019, the pro forma condensed combined net loss includes a reversal of the valuation allowance release of $48.6 million.
In the three and six months ended June 30, 2018, the pro forma condensed combined net loss includes a tax expense of $2.6 million and a tax benefit of $53.5 million, respectively, that would have resulted from the acquisition.
This data is presented for informational purposes only and is not intended to represent or be indicative of the results of operations that would have been reported had the acquisition occurred on January 1, 2018. It should not be taken as representative of future results of operations of the combined company.
