What are catch all emails?
Iris Iordanoiu Catch-All domains always return a valid response from the SMTP service, whether the email address is actually valid or invalid.
Some mail operators set up a catch-all address. For instance, if you mail [email protected], the mail administrator will forward that email to a “catch-all” address, like “[email protected]”. So they can look at all the emails sent to their mail server to see if anything important was sent to an invalid recipient.
There are 3 behaviors of catch-all email domains:
1) A non-real email address is funneled into a catch-all inbox (This does not hurt your email reputation)
2) The non-real email is bounced back, saying the user doesn't exist (This does hurt your email reputation)
3) The recipient is actually valid and the email gets delivered.
ZeroBounce identifies these domains for you. It's up to you to decide if you want to take the risk to send to these domains. If you decide to send emails to catch all domains, you should segment these into a different group in your mailing platform.
ZeroBounce has a lot of features you can use such as:
- Catch-All Domain Checker – it can identify domains that are catch all which return valid for all emails (as shown above)
- Disposable Email Checker – identifies temporary accounts used to mask real email addresses.
- Email Bounce Checker – identifies which emails will be likely to bounce if you email them.
- Toxic Domain Checker – it can identify emails that are known for abuse, spam and bot created emails.
