Email services by measured deliverability
Full rankingMeasured scores land here with our first seed-list test cycle — how we test. No estimates, no star averages.
We send real campaigns through every platform to a controlled seed list and publish what percentage actually reached the inbox.
- Inbox — landed in the primary inbox
- Tabs — Promotions and similar folders
- Spam — junk-folder placement
- Missing — accepted, then vanished
- Bounced — rejected at send time

All 14 toolsMeasured, not estimated
Deliverability Scores come only from our seed-list placement tests. A service without a test shows “Not yet tested” — never a guess.
Two scores, never mixed
The Deliverability Score is measured. The Platform Score is an editorial rubric with published weights. Features never buy deliverability points.
Methodology in the open
The formula, the bands, the verification ladder and the test protocol are published — including our own documented failure modes.
