You guys are awesome. I've been looking for a platform like this for 2 months to vet media contacts for my startup so I don't trash our domain in spam traps. This was the most effective tool I've found, and I'll be using it again on the consumer side as we develop a direct email marketing campaign.

Very useful — helped us get over the hump with our first import of 6-year old data to MailChimp. Now running much more smoothly!
— Alex English, Tampa Bay Regional Transportation Authority (TBARTA)
Thanks Data Validation! It was easy to use and after I studied the definitions, I was able to re-sort my data for upload to MailChimp. In addition, your tips about sending emails to the Accepts All emails was extremely helpful!
— Jennifer Hoskins, PHR
It's awesome!! I was able to import the cleaned list of A's and B's into MailChimp no problem, whereas before cleaning with DV, MailChimp let me know a re-opt in would be required. I'm thrilled with this service!
— Lily Starling, ParkWinters.com
We tried DataValidation on advice from a colleague. The service was easy to link to Mailchimp, and was extremely affordable.

Your service has been outstanding, and I especially liked your LiveChat feature - very helpful!

FAQ

What does your service do?

Our integrations and APIs help email marketers and ESPs automate email list maintenance. Email Assurance analyzes email addresses for deliverability on a daily basis and syncs the results back to ESP lists.

What if I just want to validate an email list?

Sure, no problem. Upload your list or link an ESP account, and purchase a One-time Tuneup. You will receive a downloadable Address-by-Address analysis with Email Assurance grades of A+ to F, and deliverability codes assigned to each email address. Grades are synced back to your ESP at purchase.

How does your service compare to your competitors?

We are faster, more accurate, and our pricing is some of the most competitive in the marketplace. With every list, you receive a free report on the quality of your email list before purchasing. Our validation process is comprehensive and we analyze millions of emails daily.

What is Email Assurance?

Never worry about the hassle of cleaning an email list again. Assured email lists are analyzed and synced daily with updated grades. Undeliverable emails are automatically unsubscribed.

How do I get free monitoring for my email lists?

Any list uploaded receives a free report including a list quality score and Email Assurance grade overview. Linked lists are analyzed daily for new subscribers and you can view your list quality trending over time on the Progress Report. Free monitoring doesn't include the Address-by-Address analysis, or daily syncing of grades.

Why is Email Assurance better than email validation?

Email validation is a reactive approach. Rather than wait until your deliverability is damaged from high bounces or stale lists, protect your email database with an Email Assurance subscription. Never worry about being blocked by your ESP.
