Email API platforms

2018. Twilio acquired email API platform SendGrid



Communications platform Twilio acquired the API-centric email platform SendGrid for about $2 billion. Twilio’s current focus is on omnichannel communication, and email is obviously a major part of that. And while it offers plenty of services around voice, video and chat, email hasn’t been on its radar in the same way. This acquisition now allows it to quickly build up expertise in this area and expand its services there.


2017. MailChimp combines email marketing with Facebook Ads



MailChimp has ventured out of its email marketing comfort zone with a Facebook advertising integration. Users of the email marketing platform can now create Facebook ads and track performance in the same platform.  Using MailChimp’s intelligent segmentation to target recent customers or active subscribers, businesses can quickly create lookalike audiences in Facebook. Facebook Ad Campaigns will roll out "gradually," MailChimp officials said. It will be available to all customers by February 2.


2014. Sendwithus gets $2.3M to help marketers optimize transactional emails



Email marketing startup Sendwithus has raised $2.3 million in additional seed funding. The service offers tools like A/B testing to optimize transactional emails — i.e., emails for specific purposes and tied to specific events, such as “reset your password” and “thanks for signing up!”. Every company sends such emails, and customers are more likely to open them, and they’re messages that “most marketers don’t get access to and don’t even think about.” Sendwithus allows marketers to test different variations of those messages without having to go through a developer. More recently, Sendwithus has added segmentation capabilities, allowing businesses to drill down on specific groups in their customer database — for example users who received an activation email but didn’t activate. Sendwithus also integrates with email delivery services like SendGrid and Mailgun.
