Sending less to the quiet ones

Mailing your least engaged group less often, to protect everyone else.

Why it works

Receiving providers judge your mail by how people treat it.

A group that never opens anything drags that judgement down for every message.

Mailing them less is how the rest of your list keeps arriving.

Use it when
You send everything to everybody and your placement has softened.
Skip it when
Your list is small and new. There is not enough history to judge anyone on.
What to watch
Your own deliverability over the weeks after you change it, not on the day.
What it costs you
You will send fewer messages, and the revenue from those messages goes too.

Put your own numbers in

There is no figure here for what this does. Nobody knows what it does on your list.
