Explain in english in other words

Good day, I have recieved email from affiliate company, they asked me send my passport copy, but I am unable to do it right now. So they send me answer like this.
"Sorry for the inconvenience. It is to inform you that you can send us blank email from your non-free (Work / Business) email address , it will verify you without sending any documents"

Can somebody explain me in other words what does mean "It is to inform you that you can send us blank email from your non-free (Work / Business) email address "
Thanks a lot

send the email without content,they probably want to verify you are not spam.

subject of your email could read,not spam or verifying account with this blank email.

should be simply enough.

This probably means the email has to be unique not free like gmail//yahoo//aol//hotmail.

If you ever bought a domain just use that email or something else

Or if you have some company email...use some domain, which is not free

Just send an email from [email protected] - as others have said, not from Gmail/Yahoo etc

Just send an email with whatever from your domain email. Like this: [email protected] not free email service like gmail/yahoo mail/hotmail/aol/...
