Automated the weekly inbox placement test
- Problem
- Inbox placement across 32 sending domains was checked by hand every Monday — sending seed mail, opening each mailbox, recording where the message landed, then transcribing the results into a sheet. Slow, and easy to skip on a busy week.
- What I built
- A Playwright script that drives a real Chrome profile through the whole test: triggers the send, reads placement per seed mailbox, and writes the results out in one pass. It runs on a schedule rather than on my attention.
- Result
- Measured on a live run across 17 of the domains: hands-on time dropped from 30–40 minutes to about 9 — a ~75% cut, with the rest of the run executing unattended. Those 17 alone account for 884 domain-level inbox placement tests a year and roughly 30 hours of manual testing time given back.
