A Customer Texted STOP Mid-Sequence: What Happens Next

It's Tuesday. Your estimate follow-up sequence is on Day 7 for a customer named Dave. Dave replies "STOP." What happens in the next sixty seconds decides whether your texting program is compliant or a liability — and it has to happen without you touching anything, because you might be on a roof when it arrives. This post is the complete opt-out playbook: the mechanics, the rules, and the setup.

This is part of Pillar A: Capture Every Lead — the opt-out companion to the complete missed-call text-back setup guide. Every texting automation you run must handle this moment correctly.

What "STOP" legally means (the 10-second version)

When a customer texts STOP — or QUIT, END, CANCEL, UNSUBSCRIBE, or any reasonable variant — they are revoking consent to receive your marketing texts. The revocation is effective immediately: from that moment, further marketing texts to that number are non-compliant. This isn't a suggestion or a preference to note for later. It's a legal event, and your system has to treat it like one.

Two things people get wrong:

• "I'll take them off the list at the end of the day." No. Suppression must be automatic and immediate. Manual end-of-day cleanup leaves a window where your scheduled Day-14 text fires to someone who opted out — a violation.
• "They only meant stop the follow-up sequence." Doesn't matter what they meant. STOP revokes consent for marketing texts from your number, period. You don't get to interpret intent.

The 60-second timeline: what must happen automatically

1. Second 0–5: the keyword is detected. Your texting tool recognizes STOP (and the standard variants) as an opt-out keyword. Every legitimate business-texting tool does this natively — it's a carrier requirement, not a feature.
2. Second 5–10: the number is suppressed. The tool adds the number to its internal do-not-text list and removes it from all active sequences — the estimate follow-up, the reactivation campaign, everything scheduled. This must happen across sequences, not just the one they were in.
3. Second 10–30: the confirmation text goes out. Exactly one reply is allowed and expected — the opt-out confirmation. See the wording below.
4. Ongoing: the suppression holds. The number stays suppressed for marketing texts until and unless the customer explicitly re-opts-in. No sequence, no campaign, no "just this once" can override it.

All four steps happen without human involvement. If any step in your setup requires someone to notice and act, the setup is broken.

The one text you're allowed to send (wording)

The confirmation text acknowledges the opt-out and nothing else. No pitch, no "are you sure," no discount to stay:

The rules for this message: send it once, send it immediately, and don't add anything to it. "Are you sure? We have a great fall special…" attached to an opt-out confirmation is exactly the kind of thing regulators cite. Confirm and stop.

What suppression does and doesn't cover

• Suppressed: all marketing and promotional texts — reactivation campaigns, seasonal specials, estimate follow-up sequences with promotional content, any bulk messaging.
• Still allowed (narrowly): purely transactional texts the customer requested or that relate to an active service relationship — e.g., "your tech is on the way" for tomorrow's booked appointment. But tread carefully: if someone just texted STOP, the wise move is to pause all automated texting to that number and handle their active job by phone or email until the dust settles.
• Never allowed again without re-permission: marketing texts. The suppression doesn't expire. Six months later, they're still opted out.

The practical policy most shops adopt: STOP means stop all automated texting, full stop. The narrow transactional exception exists in the rules, but the operational simplicity of "we don't auto-text opted-out numbers, ever" is worth more than the edge cases.

The re-permission rule (how someone opts back in)

An opted-out number can only return to your marketing texts through a fresh, explicit opt-in. What counts:

• The customer texts START (or JOIN, or your keyword) to your number.
• The customer checks the marketing-texts checkbox on a new form submission.
• The customer gives clear verbal or written consent for marketing texts again, properly logged.

What doesn't count:

• They called you about a repair. Booking service re-establishes the transactional relationship, not marketing consent.
• They didn't reply to your confirmation. Silence isn't consent.
• "I didn't mean it." If they tell you verbally they want texts again, log it as a new consent event — but a verbal claim from your memory six months later isn't a record. Get the keyword text or the checkbox.

Setting it up: the opt-out audit for your tools

Don't assume your tools handle this — verify. Run this check on every tool that sends texts:

1. Confirm keyword recognition. In your tool's compliance or messaging settings, verify that STOP, QUIT, END, CANCEL, and UNSUBSCRIBE are configured as opt-out keywords. Most tools do this by default — confirm yours does.
2. Confirm cross-sequence suppression. Text STOP from your own phone while you're mid-sequence in two different automations. Verify both stop. Some tools suppress per-campaign; you need account-level suppression.
3. Check the confirmation message. Read what your tool sends as the opt-out confirmation. Make sure it's the clean version — no marketing language appended.
4. Check the suppression list is visible. You should be able to see opted-out numbers in your tool, so you can verify status when a question comes up.
5. Check manual sends are blocked too. If you or your CSR manually text from the tool, the suppression must apply there as well — not just to automations. Most tools enforce this; verify.
6. Test the re-opt-in. Text START from your phone after opting out. Verify marketing texts can resume — and that the tool logged the new consent event with a timestamp.

Run this test before you launch any texting automation, and re-run it whenever you change tools or add a new sequence. It takes ten minutes and it's the highest-value ten minutes in your compliance setup.

The human side: what to tell your team

Your CSR or office manager will eventually get a call: "I texted STOP but I still want the appointment reminders." Train them on the script:

What the team must never do: manually re-add an opted-out number to a sequence ("they seemed like they wanted it"), text them "just this once" from a personal phone to dodge the suppression, or argue about what STOP meant. The suppression is the law's mechanism, not a suggestion — overriding it manually is the violation, not a workaround.

Compliance note

Opt-out handling sits at the intersection of TCPA (federal telemarketing law) rules, carrier requirements (10DLC business-texting registration — the carriers' registration system for texts sent by software from standard numbers; 1–7 day approval, ~$15–$20 in carrier/campaign fees), and your tools' native features. This post is general information, not legal advice. The mechanics described here are what compliant tools do — your job is to verify your specific tools do them, and to keep the consent and suppression records that prove it.
