Advanced options and email testing.
Easily authenticate emails with DKIM and SPF,
and avoid showing warnings in Gmail.
Instantly see how your emails will appear in more than 40
email clients and see if they will pass major spam filters.
SMTP2GO technology gets your emails sent, while robust reporting gives you a clear picture of what happens behind the scenes.
We've been handling email delivery for thousands of customers since 2006, and we know what it takes to get great results.
You don’t have to do anything: let us deal with blacklist monitoring, reverse DNS, DKIM, ISP throttling, blocked ports, and feedback loops with major email providers such as Yahoo, AOL, and Hotmail.
We monitor the network every minute and any issues or important announcements are shared via our status page.
Track every email that you send, from start to finish, and get your emails into inboxes.
See which of your valuable emails are bouncing or otherwise not reaching inboxes, and which recipients are unsubscribing or reporting your email as spam.
If you've tried using APIs in the past, you'll know they are often extremely complex and frustrating.
Our API is designed to be used with the minimum of mental effort from your developers. We include full examples of code in multiple languages. See our API documentation.
