Small changes to the invite note or first message can double reply rates. Here's how to test one thing at a time in Prosyo.
The method#
- Pick one variable to test (see below).
- Duplicate the campaign: Campaigns → New campaign → Copy a campaign.
- Change only that one thing in the copy.
- Split the audience: import two similar lists, or select half of one list in Prospects and use Add to list to create list B. Enroll list A in one campaign and list B in the other.
- Run both at the same limits and working hours.
- Wait for enough data, ideally 100+ people per version, before deciding.
- Keep the winner, archive the loser, and test the next variable.
What to test, in order of impact#
| # | Variable | Measured by | Example A vs B |
|---|---|---|---|
| 1 | Audience slice | Acceptance and reply rate | Founders vs VPs of Sales |
| 2 | Invite note | Acceptance rate | No note vs a short personal note |
| 3 | First message | Reply rate | A question about them vs a relevant insight |
| 4 | Call to action | Positive replies | "Worth a chat?" vs "Want me to send the guide?" |
| 5 | Channel order | Reply rate | LinkedIn first vs email first |
| 6 | Timing | Reply rate | 3-day vs 5-day delays |
| 7 | Warm-up touches | Acceptance rate | With profile visit + like vs without |
Invite note ideas to test#
| Style | Example |
|---|---|
| No note | (blank) |
| Shared context | Hi {{first_name|there}}, we're both in the {{custom.industry|B2B SaaS}} space. Would be good to connect. |
| Compliment | Hi {{first_name|there}}, enjoyed your recent post. Would love to connect. |
| Direct | Hi {{first_name|there}}, I help {{title|sales leader}}s book more meetings from LinkedIn. Open to connecting? |
Read the results#
Open Reports on both campaigns with the same date range:
- Acceptance rate → tests on the audience, invite note and warm-up touches
- Response rate → tests on the first message and follow-ups
- Positive replies → tests on the call to action and offer
Ask SalesGPT: "Compare reply rates for UK Founders A and UK Founders B."
Rules of thumb#
- One change at a time, or you won't know what worked.
- Same week, same limits. Don't compare a campaign from January with one from March.
- Don't stop too early. 20 sends tell you almost nothing.
- Winning copy goes into templates so the whole team uses it. See Templates.
Upgrade
Starter runs 1 active campaign, so A/B tests have to run one after the other. Multichannel runs 3 at once. See plans.
