What is email verification, and why is it important?

Email substantiation is the process of verifying the accuracy and deliverability of the email addresses on your list. It helps check that your messages reach real, engaged recipients, boosting deliverability and reducing backlash rates. Increased costs can arise from sending to invalid addresses, which waste resources and lead to high bounce rates, while reputation damage may occur if emails are flagged as spam, significantly lowering deliverability.

Which file types do you support?

MailVeri supports Excel files as well as CSV and text files. Files are processed line by line. Lines with no email or wrong syntax will be ignored.

The maximum filesize is 100MB . The maximum number of emails per list is 1,000,000 .
