Loss or Gain Framing in Trial-End Messages A/B Test

When many users get the trial-end message and still let the trial lapse without upgrading, support requests mention its tone, or notification opt-outs climb after it goes out, the message is not moving people. If framing really makes a difference, one version moves more users to a paid plan without raising the cancellation rate. Before launch, confirm the message is accurate: describe as lost only the features that really go away, and do not suggest data loss when the data stays available on the free plan.

Paid upgrade rate

Compare paid upgrades among all eligible assigned trial users.

Also track

• Cancellation rateCompare subscriptions with the same completed follow-up period after paid signup.
• Notification opt-out rateTrack users who turn off message notifications over the same follow-up period.
• Message-related support requestsCompare questions or complaints about message accuracy or tone using the same denominator.

• FramingCompare loss-framed and gain-framed versions of the same trial-end information.
• SpecificsInclude the same feature details and accurate access implications in both versions.
• TimingKeep channel, send time relative to trial end and frequency unchanged.
• PerceptionIf measuring how the message feels, use the same question, timing and sampling method in both arms.
• UsageReview activity segments defined before assignment.

1. 1Paid upgrade rate decides the test, but also check cancellations among subscriptions that have completed the same follow-up period after paid signup. If loss framing lifts upgrades while early cancellations, notification opt-outs or message-related support requests rise too, do not ship on that lift.
2. 2Do not pair loss framing with urgency that pushes an immediate decision; give users real time to think it over. Sending the same message again at short intervals also makes it impossible to separate the effect of the frame from the extra pressure, so test frequency on its own.
3. 3Expect the result to hold only for this channel, this send time and these feature details. Read the activity segments you defined before assignment separately, since the framing may work differently for light and heavy trial users.
4. 4Only a limited number of users may reach the end of a trial, so a small difference might not show up in this sample. Use the current paid upgrade rate and the relative lift you expect in the sample size calculator to get the users needed per arm, then compare that with your flow of eligible users whose trial is ending. If that flow cannot fill it in a reasonable time, plan a longer run or accept up front that only a larger difference will be visible.
