Has anyone used the python library [https://pypi.org/project/email-validator/] it has a check_deliverability=True option. Does this option send out actual emails to check deliverability? I only want to check if it looks like a valid email address and do not want to actually send out any emails.
The documentation mentions: check_deliverability=True: If true, DNS queries are made to check that the domain name in the email address (the part after the @-sign) can receive mail, as described above.
I am just trying to make sure it does not before testing it on a huge number of emails.
Thank you.
I did try to validate a few personal emails using this library and no email was received on those.But just wanted to make sure.
No, it does not. It would be highly impractical if it would.
