most teams i speak to don't actually know if their infrastructure is the right size for what they're trying to do.

they've just bought what they could afford or what a provider recommended two years ago.

that's fine for day one, but it's not fine for day 30.

this is the first check i run on every audit call.

THE SIZING QUESTIONS I ASK EVERY CUSTOMER:

• how many emails a day are you actually trying to send right now?
• how many inboxes do you have live?
• what's the volume per inbox per day?
• are you running warmup in parallel with campaigns, or did you stop warmup when you launched?
• how many domains are underneath those inboxes?

if you were running accounts the way people did two years ago, pushing 30 to 40 emails a day out of a single inbox, you'd be getting instant bans.

we see this all the time.

i jump on a call and the customer tells me everything's broken.

second we look at volume per inbox, it's right there on the wall.

THE CURRENT SAFE RANGE:

across the quarter million inboxes we've got in circulation, the behaviour that extends inbox lifespan from the old 3-4 month ceiling to 8-12 months is lower volume per inbox plus parallel warmup.

the trade-off is real.

you stop maximising output per inbox and start maximising the lifespan of each inbox instead.

you keep volume within the range providers consider normal.
