How this tool works

01

Deliverability signals

Links, spam-trigger words, attachments and shouting all count against you.

02

Reply signals

Length, a clear question, short sentences, and talking about them more than about you.

03

One score, nine fixes

Each failed check tells you exactly what to change.

Frequently asked questions

How long should a cold email be?

Most emails that get replies are 50 to 125 words: enough for one reason and one ask.

Are links bad?

In a first email, links lower deliverability and distract from the reply. Keep one at most, or none.

Is content enough for deliverability?

No. SPF, DKIM and DMARC, domain warm-up and sending volume matter at least as much.
