Do You Need An Actual Email To Keep Deliverability?

[Alex Read]

Hi

I've configured DKIM, DMARC, SPF.

I've also configured a catchall for the domain on cpanel, so anything sent to the domain will be received.

I want to now delete my emails in cpanel.

1) Will that impact delivability?
2) I can still send from a specific email using Elastic Email.

Just wondering if there is a check to see if the exact email is valid and if it impacts delivarability.

You probably mean email addresses (not messages).

Then no/negligible.

Sure.

Just wondering if there is a check to see if the exact email is valid and if it impacts delivarability.

RFC requires postmaster@ and abuse@ for each email/send domain.
Catch-all can impact deliverabilty negatively, but most receiving server don't check for it or would not downgrade rep b/c of that (even yahoo is catch-all).

Thanks! That makes sense.
