# How do I A/B test LinkedIn messages?
> Change one thing, keep the list comparable, and wait for enough sends. Testing Tuesday versus a new ICP at the same time teaches you nothing.

Pick one variable: the first line, the ask, blank versus note, or wait time after accept. Leave everything else still. If you change the segment and the copy, you will attribute the wrong win.

Split a similar list, not "CEOs" versus "interns." Send enough that one lucky thread cannot fool you. For a small team, 40 to 80 first messages per variant is a fair look. For invites, watch accepts over a week, not overnight.

Write the variants before you start. Do not keep editing the "losing" one mid-test. That is not a test.

On LinkedIn you cannot always know who saw the note. Use accepts and replies, not opens. For email, keep the tests in the email tool. Do not mix denominators.

When a variant wins, freeze it as the new default and test something else. Permanent "testing" is how nobody on the team knows what you send.

## Frequently asked questions

**Can I test more than two versions?**

You can, and you will wait longer for a clean read. Two is enough until you have volume.

**Should I test send times?**

Only after copy and targeting are stable. Time-of-day effects are smaller than "wrong person."

**What if both variants are terrible?**

Stop. Fix the list. Testing two bad pitches is a waste of the weekly cap.

**Do I tell prospects they are in a test?**

No. You are not a lab. You are trying to be clearer.
