Our self-service platform scans your email list(s) for undeliverable email addresses, and provides a free list quality report before you purchase. Our One-time Tuneup (aka email validation service) removes undeliverable email addresses, preventing high bounce rates and deliverability problems. Our ESP 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. Learn more
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. Learn more
Email Assurance allows your list to grow without worrying about deliverability issues. Never worry about the hassle of cleaning an email list again.
