Week 0: the two weeks a new domain earns before it sends anything cold
This is one section of a six-file deliverability pack, given here in full. It is the
part people skip, and skipping it is the single most common reason a good list burns inside a week.
What this page is, honestly. It is file 02 of six, cut at the end of week 0. The
schedule for weeks 1–4, authentication, monitoring, recovery and the 30-day checklist are not
here. Nothing on this page is clipped to make you curious — it is a real section, ending where
the section ends.
Week 0 — before anything is technical
Two weeks of ordinary email on the new domain. Not marketing. Not newsletters. Ordinary.
10 to 20 messages a day, written by a person, to people who will answer.
Subject lines a human would type. No templates.
When someone replies, you reply back. A thread with three or four turns is worth more than a
hundred one-way messages.
Sign the messages normally, with a real signature and a real reply address that a person reads.
Nothing else happens this week. There is no shortcut through it and no tool that replaces it. If
you skip week 0, you will spend the next month wondering why your open rates look like a rounding
error, and copy will get blamed for a reputation problem.

Why week 0 is given away and the ramp is not. A calendar with no warm-up rules
is a trap, so withholding this would be cruel. The volume ramp itself, the authentication section
and the recovery procedure are what the pack sells, because they are the parts that need to be
right on the day the domain starts to wobble.
