right now my company structures our no reply emails like this:
noreply@[subdomin].[domain].com (example: firstname.lastname@example.org)
I want to know if something like this is acceptable:
noreply_[subdomain]@[domain].com (example: email@example.com)
Obviously the emails will send no problem, but my concern is being marked as spam when, of course, it's not, the user signed up with us. If you are wondering as to the why, it's due to how our Send Grid is set up.
I guess this boils down to: Is the first example any better than the second example in terms of deliverability?
