Case studies

Viral referral campaigns, taken apart

Milestone referral programmes, sweepstakes, and waitlists run by the BAMF team — the growth agency behind newsletter.app. Each write-up covers the mechanic that was built, not just the outcome, so you can rebuild it on your own list.

These write-ups are being prepared. Entries marked Draft have their mechanics outlined but no confirmed results — nothing on those pages should be read as a published figure.

Referral campaigns, built into your newsletter

newsletter.app is bringing these mechanics — milestone rewards, sweepstakes, and waitlists — into the product alongside paid growth, so one tool covers both halves of acquisition.
