Mailgun Technologies, based in San Antonio, Texas and led by CEO Will Conway, provides email API technology used by over 150,000 companies to send, receive and track email from within applications. Its platform combines infrastructure, developer documentation, developer tools and customer support to deliver high deliverability across transactional and marketing use cases. Software development teams at Lyft, GitHub, Iterable and Indeed embed Mailgun to power high-volume and high-frequency messaging. The company intends to use proceeds from the transaction to expand its platform and accelerate product roadmap initiatives. The article does not disclose revenue, valuation or other financial metrics. Mailgun positions itself as a developer-first email infrastructure solution. Mailgun is an email delivery service that provides developers an API-driven way to programmatically send emails. The product is focused on developer experience and is positioned alongside services like Amazon SES and SendGrid rather than consumer tools such as Mailchimp. Its user base includes customers such as Slack, GitHub, Stripe and Lyft. Mailgun was Y Combinator-incubated, was acquired by Rackspace in 2012, and has now been spun out of Rackspace. The company says it will use new funding to accelerate its product roadmap, drive growth initiatives and expand customer support. William Conway, previously GM of Mailgun at Rackspace, will become the new company's CEO. Mailgun offers a programmable email platform for developers, enabling sending, receiving, parsing, storage, and search of email via a straightforward API. The product has evolved from a SendGrid-comparable feature set into a more robust email service provider. Mailgun charges based on messages sent/received and storage used rather than per-mailbox pricing, with a free tier and low-cost paid plans. The service powers about 600 clients — roughly 400 on the free plan and almost 200 paid customers. Pricing details in the article note a free plan allowing 200 messages/day and a paid plan at $1 per 1,000 messages plus $1 per GB/month of storage. Founder Ev Kontsevoy positions Mailgun as changing how developers integrate email into apps, likening the ambition to Twilio for email.
