When did managing your mailboxes become a headache?
When I started doing outbound, managing a few mailboxes was pretty easy.
Then the number slowly increased and suddenly I was keeping track of domains, DNS, sending limits, mailbox health, bounces, etc.
At some point it felt like I was spending more time maintaining the setup than actually working on campaigns.
For people running larger outbound setups, do you manage everything yourself or use some kind of managed infrastructure?
I'm curious where other people draw the line.
