Verify email accounts with Postmark?

[Jamie Lawrence]

Is it possible to verify email accounts with Postmark?

We obviously check the email addresses with a basic regex but, for example, one company just created 7 new users 3 of which had a misspelt domain name! *sigh* users!

When we tried to send emails to these users, Postmark obviously generated a hard bounce but that was quite removed from the user process of adding those users (users are added and invited in separate steps). It's even more important when a user is changing their own address that we catch typos to prevent them locking themselves out — and confirmation links/emails have their own problems. 

Is it possible to use Postmark to validate that those addresses exist without actually sending an email?

Hi Jamie,

It is not possible to verify the address without sending. The remote server still has to respond to the sent email to say if it exists or not. SMTP does have a VRFY command, but it is not supported everywhere. We've been thinking about automatically correcting misspelled domains, since this happens a lot.

Hi Jamie, Chris

Kicksend released a javascript to suggest corrections to misspelled email domains - it won't guarantee you won't get any, but should help a lot.
