When someone replies asking to stop, they are added to your opt-out list and every future campaign skips them. Add your own blocklist for numbers that must never be messaged.

How it works
Offer a way out
A short unsubscribe line can be added to your campaign.
Replies are caught
A reply asking to stop adds the person to your opt-out list.
Skipped from then on
Every later campaign leaves them out automatically.
Why businesses use it
Fewer reports
People who can opt out do not need to report you.
Your blocklist
Add staff, competitors or anyone who must not be messaged.
Always on
No need to clean every list by hand.
What it costs
Every new account starts with a free trial. After it, a free plan keeps sending a few messages a day, and a one-time upgrade — no subscription — unlocks everything.
