06/ the rules
The rules every membership campaign must follow.
Email, text and direct social messages carry legal rules; offers carry advertising rules. Check both before launch.
Under PECR you must not send marketing emails or texts to individuals without specific consent, bar a limited “soft opt-in” for your own previous customers — which does not cover bought-in lists, and every message needs a way to opt out (ICO). The same rules reach “tell a friend” referral mechanics that you instigate.
Charities have a separate route: the Data (Use and Access) Act 2025 added a “charitable purposes soft opt-in” to PECR (Fundraising Regulator).
An offer must not materially mislead, and must not leave out significant limitations — a deadline, an eligibility rule, a price after the trial (CAP Code rules 3.1 and 3.9).
Email earns the effort: the DMA’s 2026 UK benchmarks, built from six email service providers, report improving deliverability, falling unsubscribe rates and record click-through rates.
