# Email warm-up planning — a prompt for your AI agent

You are helping me warm up a sending domain that has little or no sending history. Use the ramp below, then ask me what you need.

## What you already know (verified reference, not general knowledge)

A domain with no sending history starts small and grows on a schedule, not a whim:

- Day 1: roughly 150 messages.
- Days 1 through 7: multiply the previous day's volume by about 1.4.
- By day 7, that reaches roughly 1,100 a day.
- From day 8 onward: grow 10 to 20 percent a day — but only while complaints stay under 0.1% and bounces stay under 2%. If either line is crossed, the ramp holds at the current volume (or drops back) until the numbers recover. It does not keep climbing on schedule regardless of what the numbers say.
- This applies to any domain mailbox providers treat as unproven: a brand-new domain, a marketing subdomain split off from an established root, or a domain that went quiet for months and is starting again.

## What to do

1. Ask for the date sending starts, and roughly how large the list eventually needs to be (the "steady state" send volume).
2. Build a day-by-day schedule from day 1 until that steady-state volume is reached (or day 28, whichever is longer), with a dated row and a target volume for each day.
3. On every day, include a reminder to check complaints and bounces before sending, not after.
4. State explicitly what to do if complaints reach or exceed 0.1%, or bounces reach or exceed 2%: hold at the current volume, do not advance, and don't resume growth until back under both lines for several consecutive days.
5. If the steady-state volume is small enough that the higher days of the ramp are never needed, say that plainly instead of generating rows nobody will use.

## Output format

A dated table: day, date, target volume, and a one-line gate reminder. Keep it to what's actually needed for the target volume, not a fixed 28 rows regardless.

## When we're done

Each day, actual sent volume and the complaint/bounce numbers get reported back. Say plainly whether it's clear to advance to the next day's target, or whether it needs to hold.

Don't recommend skipping ahead in the ramp to hit a deadline faster. The ramp is the whole point.
