What Happens When a Lead Replies STOP in Follow Up Boss?

A lead replies "STOP" to one of your texts. It's easy to read that as a door closing — but what it really is, is an instruction with legal weight behind it. Under the Telephone Consumer Protection Act (TCPA), that one word withdraws the permission that made your texting okay in the first place. Here's what that means for agents using Follow Up Boss, what has to happen inside any texting tool you've connected to it, and how SendMate handles the whole thing automatically.

STOP Is a Consent Event, Not Just a Preference

Business texting runs on consent. As we covered in our TCPA compliance guide for real estate texting, the TCPA requires "prior express consent" before sending marketing texts — for most Follow Up Boss agents, that consent comes from the lead submitting their phone number through a form that indicated they may receive texts.

A STOP reply is that same lead exercising the other half of the deal. The TCPA requires that recipients be able to stop receiving texts by replying "STOP" or similar keywords, and once they do, the texting has to end immediately and stay ended. This isn't a soft preference like "prefers email" — it's a revocation of consent.

The penalty math makes the stakes concrete. TCPA violations carry penalties of $500 per unsolicited message, and up to $1,500 per message if the violation is deemed willful. A text sent after a lead replied STOP is about as far from a gray area as it gets — the recipient explicitly told you to stop, in writing, in the same thread. That's why opt-out handling isn't a nice-to-have feature in a texting tool. It's the feature.

What Follow Up Boss Does With a STOP Reply

Follow Up Boss handles opt-outs natively for texts sent through its platform. When a lead replies STOP to a text you sent from your FUB number, that opt-out is recognized where the conversation actually lives — your own number, your own inbox, one thread.

That last part matters more than it looks. Because the STOP reply arrives in the same conversation as everything else, you can see it, your team can see it, and the record of the opt-out sits right next to the record of the original consent. Compare that with texting services that route messages through a separate number: the lead's STOP goes to a number that isn't yours, and you need to make sure opt-out handling is properly configured on that service's side. We wrote more about why that matters in why your FUB texts should come from your own number.

Why Your Texting Tool Has to Honor It Too

Here's the part that trips people up. Say a lead is on a follow-up sequence in Follow Up Boss — a text on day 1, day 3, day 7, day 14. On day 3, they reply STOP. The day 7 and day 14 texts were queued up before the lead ever opted out. If the tool doing the sending doesn't check for the opt-out, those texts are still on the calendar.

That's why any texting tool worth using has to treat a STOP reply as a hard halt, not a suggestion:

• Pending messages get cancelled. Anything queued for that contact stops before it sends.
• Future sends get blocked. The contact can't quietly re-enter a sending queue next week because a new task dropped.
• The state persists. An opt-out honored today and forgotten next month isn't honored at all — "stay stopped" is part of the requirement.

This is the same principle behind every guardrail we recommend in a texting tool: compliance should be the default behavior of the software, not something you have to remember. If your tool lets a scheduled text slip out to a lead who opted out last week, that's a tool problem — but it's your liability.

How SendMate Handles a STOP Reply

SendMate builds this in as auto-STOP detection. When a lead replies with an opt-out, SendMate detects it and does two things, automatically:

• Writes a do-not-text state for that contact. The lead is marked as opted out inside SendMate, so the decision isn't riding on anyone's memory.
• Halts the sending. Pending messages for that contact are auto-stopped, and future sends to them are blocked. Texting ends the moment the lead opts out — and stays ended.

So in the day-3 STOP scenario above, the day 7 and day 14 texts simply don't go out. You don't have to catch the reply in time, remove the lead from a plan, or hope nobody on the team re-adds them. The do-not-text state does the remembering.

Auto-STOP is one piece of a deliberate careful-sender design. SendMate sends from your own Follow Up Boss number, so the STOP reply and the record of honoring it live in your own FUB inbox. A Send Window keeps texts inside reasonable local hours. Landline detection converts un-textable numbers into call reminders. And on the Brokerage plan, DNC and litigator screening integration lets you scrub lists before you ever send. You review what goes out, you set the schedule, and nothing sends behind your back — auto-STOP is what that same philosophy looks like on the receiving end.

What To Do After a Lead Opts Out

The software handles the halt. Here's the human side of doing it right:

• Leave the opt-out alone. Don't re-enroll the contact in text-based follow-up plans, and make sure everyone on your team knows the contact is off-limits for texting.
• Keep the record. The STOP reply sitting in the conversation thread is your documentation that the opt-out was received and honored. Don't delete it.
• Treat re-engagement carefully. If the lead later reaches out and clearly asks to hear from you by text again, that's a new consent conversation — document it just as clearly as the opt-out. When in doubt about a specific situation, ask your compliance advisor before you resume.

Frequently Asked Questions

What does it mean when a lead replies STOP in Follow Up Boss? It revokes the lead's consent to receive texts. Under the Telephone Consumer Protection Act (TCPA), recipients must be able to opt out by replying STOP or similar keywords — and once they do, the texting has to end immediately and stay ended. Treat it as binding, not a preference.

Does Follow Up Boss handle STOP replies automatically? Yes — for texts sent through its platform. Because the reply lands on your own number, the opt-out record sits in the same thread as the original consent. If you use a texting service with a separate number, confirm opt-out handling is configured on its side.

How does SendMate handle a STOP reply? SendMate's auto-STOP detection spots the opt-out reply, writes a do-not-text state for that contact, auto-stops any pending messages, and blocks future sends. Texting ends the moment the lead opts out and stays ended — no one has to catch the reply in time.

Can I text a lead again after they reply STOP? Keep them stopped. Don't re-enroll the contact in text-based follow-up, and preserve the STOP reply as your record of honoring the opt-out. If the lead later clearly asks to be texted again, document that new consent and ask your compliance advisor first — this is general information, not legal advice.

What are the penalties for texting a lead who opted out? TCPA violations carry penalties of $500 per unsolicited message, and up to $1,500 per message when the violation is deemed willful — which is why opt-out handling should be automatic in whatever texting tool you use.

The Bottom Line

A STOP reply is the system working exactly as intended: the lead told you their preference, and every layer — Follow Up Boss, your texting tool, and you — honors it. Honoring an opt-out instantly costs you nothing. Missing one can cost $500 to $1,500 per message that follows it.

SendMate's job is to make the honoring automatic: detect the opt-out, write the do-not-text state, halt pending messages, block future sends. The careful sender isn't the one who never automates — it's the one whose automation stops on a dime.
