Email Verification Services

We want to make sure your emails are sent only to accurate addresses that are still in use, so that your message can land in the inbox without bouncing back. To keep your email lists “clean”, we will check the validity of the email addresses in your database each time we’re launching a campaign. This process of email validation and authentication is a key piece of the deliverability puzzle.

How We Do It?
Our email verification services are at the heart of Senders Protocol ™. They entail an intricate sequence of steps we repeat each time you expand your email lists.

Email Verification Explained

In a nutshell, email verification services combine a range of validation and authentication processes to make sure that email addresses are properly formatted, their domains are functional and legitimate, and that these addresses are actively used.

Verification also ensures adherence to those essential protocols like DMARC, DKIM, and SPF. The purpose of this process is to reduce the risk of sending emails to invalid, fake or inactive addresses and to boost deliverability as well as security.

There's a lot of really really awesome things. I would say the team is just very open for us. Testing things out - different segments, different copy and they turn around time is just very, very quick which I really, really appreciate and that's been consistent since day one.
