Product changes, newest first.
Catch-all addresses now get a severity tier. A clean address on a free-provider domain is low risk, and a company domain is high risk. The score, the safe-to-send flag, and policy decisions use the same tier.
Open any result to see every field of the check: format, domain, mail server, mailbox, risk, and the reasons behind the score.
When an address is malformed, the check form tells you why before you run it.
Connect SendGrid, Mailgun, Postmark, or Amazon SES. Bounces, complaints, and unsubscribes update your suppression list.
Addresses with an unknown result are checked again later, when the mail server is more likely to answer.
Each list gets a fix plan with the rows to keep, fix, review, or suppress, and files you can export.
