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.

Upload an email list, use one of our supported ESP Integrations, or take advantage of our Real-time and Batch Verification APIs. 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.

No way that would have been possible without your service!

In addition, your tips about sending emails to the Accepts All emails was extremely helpful! I was able to import the cleaned list of A's and B's into Mail Chimp no problem, whereas before cleaning with DV, Mail Chimp let me know a re-opt in would be required. See the percentage of deliverable, engaged, and undeliverable email addresses on your list prior to purchasing!
