Check whether an email address is worth sending to — format, mail server (MX), free vs business, disposable and role-based detection.
No AI, just DNS and pattern checks. For any address it reports:
Bounce rate is the fastest way to wreck a sending domain. Removing invalid, no-MX and disposable addresses before you send is the single biggest lever on it. Keep your bounce rate under about 3%; above that, mailbox providers start throttling and your good emails land in spam too.
A valid-format, business, MX-present, non-disposable, non-role address is a clean send. Role-based addresses are worth keeping but deprioritising, they reply less. Anything with no MX or a disposable domain should come straight off the list.
Format validity, whether the domain has a mail server (MX record), free vs business domain, disposable addresses, and role-based addresses such as info@ or sales@.
Yes. Removing invalid, disposable and no-MX addresses is the single biggest lever on bounce rate. Keeping bounces under about 3% protects your sending reputation.
Addresses like info@ or sales@ reach a shared inbox and tend to reply less, so deprioritise them rather than leading with them.
No AI, and it is free. It performs DNS/MX lookups and pattern checks, one verification per email.
