Read the evidence
How to read an inbox placement test, run a pilot without inferring causation, and judge a warmup claim before you buy.
Read an inbox placement test
A sample report, line by line: what the numbers mean, what the sample allows you to say, and what no placement test can prove.

The protocol to write before you connect a mailbox: one question, a hold-out group, a stop rule, and the access you plan to revoke on day one.
Warmup permissions and security
OAuth scopes, app passwords and SMTP access: what each one lets a warmup service do, how revocation works, and the checks to run before you connect a mailbox.
