First step in delivery
Ever trawl through your logs and notice that there is a delivery problem somewhere? I’m sure everyone sending email in any volume has.
What’s the first thing you do when you discover a block?
A: Decide that something broke on your end and set about trying to figure out what you did to trigger the block.
B: Decide that something broke on the ISP end and set about trying to find a human to fix it.
C: Unsub the recipients and stop mailing that domain.
D: Decide it’s a temporary failure. Wait and see if it happens again.
E: Call a delivery specialist or Return Path or your ESP to demand they pick up the bat phone.
F: Dig through cards you acquired at MAAWG and contact some random person at that ISP for help.
G: Run around in circles wildly.
H: Ask every other ESP you know if they are being blocked too.
