Same Offer, Same Audience, Third Time Around. The Best Three Days of the Whole Campaign.
A leading telecom operator in Croatia sent two waves of its own messages for the same offer. Lexi wrote the third. Same product, same channels, same audience.

Numbers are total daily activations of the offer per campaign wave, from the client's internal dashboard (July 2026).
The offer was simple: unlimited mobile data for members on a family plan, sent out over push, RCS, and SMS. The telecom ran it in three waves over the summer. The first two waves, written in-house, followed the pattern most repeat offers do: a decent day one, then a fast fade. By wave three, the same audience had already seen this exact offer twice, so a weaker response looked like the safe bet. Lexi wrote the third wave instead, and the pattern broke: more people activated, the drop-off slowed down, and the campaign got its best three-day stretch yet, on a message the audience had technically already said no to, twice.
A Leading Mobile Operator in Croatia
The client is a leading telecom operator in the Croatian market. Its marketing team communicates offers to customers through push notifications, RCS, and SMS. The campaign in this case study offered unlimited mobile internet to members of a family mobile plan, run in three waves over the summer of 2026.
The Same Offer, Sent Twice Already, Losing Steam
By the time the third wave was ready to go out, the audience had already received this exact offer twice. Wave one produced 722 activations over three days. Wave two produced 740, only a small improvement, and both waves lost more than a third of their peak-day activations by the very next day.
Ordinary campaign logic says a third message about an offer the audience already saw and passed on, twice, should perform worse, not better. Diminishing returns on repeat exposure is what most teams expect, and plan for.
The real barrier wasn't the offer. It was doubt. Unlimited data sounded good enough to make people suspicious: what's the catch, and what happens to the bill afterward? The first two waves hadn't addressed that doubt directly.
Same Offer, Same Channels. A Different Psychological Angle.
For the third wave, Lexi wrote the push, RCS, and SMS messages instead of the telecom's own team. The product didn't change. The channels didn't change. The audience was the same people who had already seen this offer twice. What changed was the psychology behind the words.
- A new trigger, the same brand voiceThe messages targeted a different motive than the telecom's own copy: specifically, the role of the person whose phone acts as the family's hotspot. The brand's tone stayed exactly as it was.
- The catch, said out loudThe main barrier to activation was suspicion: what's the catch? Every message addressed it directly: the offer switches itself off automatically, and the bill stays the same.
- A method, not a spark of inspirationEvery message came out of Psihopis, Lexi's map of motives and mechanics for a specific offer, with two variants written for every claim. That's what makes a result repeatable, not a one-off.
Wave Three Beat Both Previous Waves, With the Same Audience
The offer was communicated in three waves. Daily activation numbers below are for the day the wave was sent, and the two days after.
Daily offer activations: day of send, one day after, two days after
| Wave | Written by | Day of send | +1 day | +2 days | 3-day total | Day+1 retention |
|---|---|---|---|---|---|---|
| Wave 1 | Telecom | 350 | 228 | 144 | 722 | 65% |
| Wave 2 | Telecom | 387 | 188 | 165 | 740 | 49% |
| Wave 3 | Lexi | 466 | 431 | 234 | 1,131 | 92% |
Day+1 retention: activations one day after sending, as a share of the peak (day-of-send) activations.
Wave three didn't just win on day one. It kept people coming back. 431 activations on day two alone beat the entire peak day of both earlier waves. And 92% of the opening day's activations were still landing a day later, against 49% and 65% for the two waves before it.
A/B results by individual message variant are still being processed by the client.
Repeat-Offer Fatigue Isn't Fixed by a New Offer. It's Fixed by a New Angle.
Most teams assume that sending the same offer a third time to the same audience means diminishing returns, and plan for a smaller number. This campaign points somewhere else: the ceiling wasn't the offer, it was the angle. Same product, same channels, same audience. The only variable that changed was the psychology behind the words, and that was enough to produce the campaign's strongest wave.
