Mailgun, a San Antonio, Texas-based email automation platform for developers, secured $50m in funding.
The round was led by Turn/River Capital with participation from Scaleworks and Rackspace.
The investment and related spin out transaction will establish Mailgun as an independent company from Rackspace, and will be used to accelerate the company’s product roadmap, drive growth initiatives, and expand customer support.
Led by CEO William Conway, who previously served as GM of Mailgun inside Rackspace, Mailgun provides developers with a set of APIs that allows users to send, receive, and track email from within their applications – without managing an email server or becoming an expert in email setup, operations and deliverability.
This full-featured email service allows customers to engage their users, and optimize the email capability of their application and websites with all the analytics and data needed to measure the impact.
Development teams such as Slack, GitHub, Stripe, Lyft, OfferUp, Zapier and Cinemark integrate their products with Mailgun.
The company also has offices in Austin and San Francisco.
