Twilio, a cloud communications platform developer, has completed its acquisition of email marketing platform SendGrid. The initial agreement announcement in October valued the all-stock transaction at around $2bn, but the transaction ended up closing at approximately $3bn.

With the acquisition, Twilio promises to offer a platform to manage all important communication channels, including voice, messaging, video, and email; scalability and reliability to support growing businesses; and the ability to deliver personalised messaging based on the customers’ preferred form of communications.

“Effective customer engagement is a strategic imperative for every company. With SendGrid now a part of Twilio, our goal is to provide a complete platform for every form of customer engagement,” said Jeff Lawson, Twilio co-founder and CEO. “Through our mutual developer-first approach, we empower the builders of the world to create magical customer experiences unique to every interaction.”

SendGrid has become a wholly-owned subsidiary of Twilio, becoming Twilio SendGrid. Its CEO, Sameer Dholakia, will continue to lead the firm, reporting to Lawson.

“Together, we serve more than 140,000 active customer accounts and power more than 600bn annualised interactions each year. We have a shared vision, a shared model and shared values that will set us up for success,” said Dholakia. “As we join forces today, I’m more confident than ever that we can accelerate our vision of creating one unquestioned platform of choice for developers and companies around the world and help them transform the way they engage with their customers.”
