What constitutes a "valid business email", exactly? I entered one, clicked "verify", and was warned to "enter a valid business email." I assure you, I did. What's the trouble?
A valid business email is one where you should be able to receive and send mails. If you have a 'catch all' email id, the system does not accept that.
Having said that i must say our algorithm is deliberately a bit aggressive (so as to prevent spam).
Your email could very well be a false positive. Could you write to support@sess.email from the business email in question. I'll be happy to look into it and whitelist it.
What technical means do you use to detect a catch-all address? I know of no reliable method for that purpose, since receiving server cooperation would be required and could not be trusted.
This won't detect a catch-all address, but will almost always detect a catch-all domain: send email to [long random string]@domain. Does it bounce or is it accepted?
