SMS Marketing
Best Practices.
Run Programs That Perform — and Stay Compliant
A well-run SMS program earns trust, drives revenue, and keeps carriers happy. A poorly run one bleeds opt-outs, triggers filtering, and exposes you to legal risk. These practices are the difference between the two.
Do These Four Things.
Everything Else Follows.
These aren't advanced tactics. They're the foundation. Programs that ignore them become expensive problems. Programs built on them compound in performance over time.
Program Clarity
The must-have disclaimer stuffMake it obvious what people are signing up for. No surprises. Surprises create complaints, complaints create carrier flags, and carrier flags hurt your entire list's deliverability.
- Program name and what subscribers will receive
- Expected frequency ("msgs per week" or similar)
- Reply STOP to opt out, HELP for help
- Msg & data rates may apply
- Contact info or link to full terms
Message Frequency
Cadence is a promise, not a numberDon't treat your list like an unlimited group chat. The right cadence depends on what you send, what business you're in, and what subscribers expect. Set the expectation up front, then stay consistent with it.
Content Mix
Promos pay bills. Value builds the list.Promotions drive revenue, but a list that only receives discount texts trains subscribers to tune out — or opt out. Blend in messages that strengthen the relationship. The best programs mix three types of content.
Express Consent
The foundation everything else rests onAlways collect express prior written consent before sending marketing texts. A purchase or a past transaction does not equal permission to text. This is the most important practice on this page.
- Opt-in must be affirmative and explicit — no pre-checked boxes
- Past purchases ≠ SMS permission. They are separate.
- Store consent records: timestamp, source, exact disclosure shown
- STOP must immediately and permanently stop all messages
- HELP must return a useful response with contact info
