Company overview. Mailgun Technologies, Inc. (commonly "Mailgun") is an email delivery platform company founded in 2010 by Ev Kontsevoy and Taylor Wakefield, a Y Combinator graduate that was acquired by Rackspace, spun back out in 2017 with backing from Turn/River Capital, and later acquired by Thoma Bravo. Mailgun is now a subsidiary of Sinch AB, a Swedish CPaaS provider publicly traded on Nasdaq Stockholm, which bought the company (then part of the Pathwire group, alongside Mailjet and Email on Acid) in September 2021 for about $1.9 billion ($925 million cash plus Sinch shares). Mailgun's headquarters are listed at 112 E Pecan St., San Antonio, TX. No standalone revenue or headcount figure for Mailgun was located; at acquisition Sinch reported that Pathwire served 100,000+ customers, and Mailgun's site cites 150,000+ businesses.
Products / services. Mailgun operates an API-driven email delivery platform: RESTful email sending/receiving APIs, SMTP relay, email validation and verification, deliverability and inbox-placement tools, email testing, dedicated IPs and IP pools, suppression management, subaccounts, templates, and analytics. Customers have included Lyft, Microsoft, GitHub, and Reddit.
Patent-litigation posture. Mailgun is an operating company, not an NPE: it appears in the tracked data once, solely as a defendant (1 defendant case, 0 plaintiff cases). The single tracked suit is Peter Henrik Pedersen v. Mailgun Technologies, Inc. (6:21-cv-01153), filed November 2021 in the Western District of Texas (Waco Division) before Judge Alan Albright — a venue known for plaintiff-friendly patent dockets.
Notable case. Individual inventor Peter Henrik Pedersen asserted U.S. Patent No. 6,965,920 ("Profile Responsive Electronic Message Management System") against Mailgun's email marketing products as part of a broader campaign that also named Google, Microsoft, Ziff Davis, Oracle, Salesforce, Zoho, and Verizon/Yahoo, among others. Mailgun was represented by Goodwin Procter and Slayden Grubert Beard; the case progressed through claim construction and was ultimately dismissed via a joint stipulation referencing a settlement, with Pedersen's claims dismissed with prejudice (RPX, Unified Patents, PatSnap/PACER records).
