What are SMS opt-in best practices?

Last reviewed July 22, 20261 min readReviewed by BroadNet engineering

Quick answer

Collect explicit, informed opt-in before sending marketing SMS: tell subscribers what they are signing up for, how often you will message, and how to stop; keep an auditable record of when and how consent was given; and confirm the subscription with a single welcome message. Clean, consented opt-in is the foundation of both compliance and deliverability — bought or scraped lists fail on both.

The long answer

Everything worth knowing, nothing that isn't.

§01

Make consent explicit and informed

Use a clear opt-in (a checked-by-the-user box, a keyword to a short code, a double opt-in) that states the program, expected frequency, and that message rates may apply. Pre-checked boxes and buried terms do not count. See /answers/sms-compliance-checklist.

§02

Keep proof

Record the timestamp, source, and exact language of each opt-in, so you can demonstrate consent if challenged and suppress correctly on opt-out. See /answers/what-is-dnc.

§03

Confirm, then honour STOP

Send one welcome/confirmation message, then process STOP and unsubscribe instantly and permanently. See /answers/how-to-handle-sms-opt-outs.

§04

Never buy lists

Purchased or scraped numbers have no consent, tank your delivery rate, and expose you to penalties. Grow the list from your own opted-in customers. See /answers/how-to-improve-sms-delivery-rates.
