Verify Your Email List to Improve Deliverability

Reduce bounces and improve your list quality with DataValidation's email list maintenance integration. Whether you are looking for a one-time email verification cleanup or want a solution that can grow with your list, our email list integration will keep you in compliance with MailChimp's standards.

Free List Health Report

Simply use your MailChimp account credentials to signup and receive free list quality reports. Each email list is given an overall deliverability rating based on the health of the subscribers on the list. This information can be used to determine if a One-time Tuneup is necessary.

One-time Tuneup

A One-time Tuneup cleans your email list and gives you access to address-by-address deliverability data. After purchasing, you receive a downloadable analysis, and results are synced back to your lists inside of MailChimp with undeliverable emails unsubscribed. Cleaning your MailChimp email list can help improve your email marketing reputation.

Monthly Email Assurance

Email Assurance scans your email lists daily for undeliverable emails, and automatically unsubscribes bad addresses before they bounce and hurt your deliverability. Maintain your growing email list worry-free with an Email Assurance subscription. Every One-time Tuneup includes 30 days free of Email Assurance.

What People Are Saying

In less than two weeks we went from an 87% reputation to 98% with SendGrid. We have pleased the ISP gods thanks to your team!
— Mikhail Avady, IP SmartUP
I was a bit desperate yesterday after MailChimp blocked one of my uploaded lists. It is clear that DataValidation solved this very quickly. Thanks a lot!
— Yves Van Hee, Atradius
DataValidation saved my life! I had to migrate the newsletter campaigns from a self-programmed system to Zoho Campaigns, and I recognized, too late, that the dataset was horrible. Zoho blocked me during the first campaign.
— Hans-Henning Schulz, Deutscher Verlag für Gesundh
I LOVE your service. I’ve used the MailChimp integration, which works like a dream. I will be recommending your service to all my MailChimp clients as a “good practice” tool to add to their arsenal.

Thanks very much for cleaning my list, the service works very well.

Super. I didn't expect the Mailchimp integration. It made everything painless.

The service I have received has been fantastic. Without any doubt the best online service I have ever had. Thank you!
— Andrés Gómez-Peña, IDB
On our first eNews to nearly 2,500 subscribers, we had only 5 bounce-backs and 7 unsubscribes. No way that would have been possible without your service! Thanks, DataValidation, for keeping us in compliance!
— Jodie Rogers, University of Oregon
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.
— Jared Criscuolo, seededbox.com
Y’all have a great service with a nice clean, user friendly interface. Glad to be able to have multiple versions of our list to make use of. No doubt I’ll be using the services of your company again in the near future.

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!

We tried DataValidation on advice from a colleague. The service was easy to link to Mailchimp, and was extremely affordable.
— Jodie Rogers, University of Oregon
We are VERY satisfied. Your service has refreshed our stale mailing list and contributed to the surrealistic celebration of the Domestic Research Society's 10th anniversary - high in the Julian Alps!
— Alenka Pirman, Domestic Research Team
Your service has been outstanding, and I especially liked your LiveChat feature - very helpful!
