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.
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.
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.
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.
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.
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.
