Reactivating old customers by text works for a boring reason: it is fast, read within minutes, and nearly impossible to ignore. It fails for an equally boring reason: most reactivation texts are sent without specific consent, from an unfamiliar number, with copy that reads like a scam, which is why reports and blocks happen before anyone reads the offer. Project Broadcast's analysis of more than 170 million texts shows the mechanics clearly: once non-conversational messages pass 160 characters, two-hour reply rates fall from 8.15% to 5.18% and unsubscribe rates rise from 0.15% to 0.26%. Short, identified, relevant messages win. This article gives you the rules first, then the word-for-word examples.

Everything below assumes documented consent that covers marketing text messages. If you cannot prove that consent, your reactivation starts on email or the phone, not SMS. This article is general information, not legal advice; have a qualified attorney review your messaging program.

Key takeaways

  • Revocation is easy and must be honored fast: consumers can stop texts in any reasonable manner, and the FCC requires requests be processed within a reasonable time not to exceed 10 business days.
  • US carriers require A2P 10DLC registration for application-to-person texting, and unregistered traffic gets filtered and charged extra carrier fees.
  • Textmagic's 2025 consumer survey found 41% of ignored business texts were seen as irrelevant and 39% seemed not entirely legitimate - relevance and clear identity are spam prevention.
  • Almost 70% of surveyed consumers had blocked a business number, with 48% of those citing excessive frequency or irrelevance.
  • Keep reactivation texts under 160 characters, identify the business, reference real history, and make saying no easy.
  • Send one opener and one follow-up. Stop on any reply, and keep the suppression list checked on every send.

Why reactivation texts get reported

Five causes explain nearly every spam report, and four of them are visible before anyone types a reply.

  • No specific consent. A phone number collected for a callback or an old imported list is not permission to send marketing texts. The FCC's consumer guidance is direct that commercial texts require written consent, and the classic mistake is texting first to "see what happens."
  • Frequency. Textmagic found nearly 70% of consumers have blocked a business number, and 48% of those did so multiple times, citing excessive frequency or irrelevance. Three texts in a week reads as a campaign; one thoughtful text reads as a person.
  • Unknown sender. 39% of ignored texts were ignored because the consumer was not sure the message was legitimate. If the first message in a thread does not name your business and the reason you have their number, you are indistinguishable from a scam.
  • Long, link-heavy copy. Project Broadcast's data shows the 160-character cliff on reply rates and the accompanying rise in unsubscribes. Scam-shaped formatting, wall-of-text plus a shortened link, triggers both carrier filters and consumer suspicion.
  • Unregistered sending. Twilio's A2P 10DLC documentation explains the consequence plainly: unregistered traffic receives lower throughput, more carrier filtering and additional fees. Filtered messages are also more likely to be reported when they do arrive, late and out of context.

The HBR retention research adds the reason it is worth doing carefully at all: acquiring a new customer can cost five to 25 times more than keeping an existing one. An old customer is closer to the cheap end of that gap than a stranger is, which is precisely why you should not burn the relationship with a lazy blast.

The rules before you send

  1. Verify consent records. You need documented, specific consent for marketing texts, captured with the disclosure the person actually saw.
  2. Suppress the right people. Anyone who opted out, complained, or hard-bounced goes on a permanent suppression list that every send checks.
  3. Register your number. A2P 10DLC brand and campaign registration, or toll-free verification, before the first campaign.
  4. Identify yourself in message one. Business name, plus why they are hearing from you.
  5. Keep it under 160 characters where you can and one question per message.
  6. Respect quiet hours. The FCC treats texts as calls, so stay inside the 8am-to-9pm window in the recipient's time zone.
  7. Process STOP immediately. Modern platforms can honor opt-outs instantly, which is safer than the 10-business-day ceiling.

If any of that sounds like a lot, that is the point: these rules are what separate a reactivation worth running from a spam report waiting to happen. Our SMS compliance guide covers consent language, registration and record-keeping in detail.

The examples

Every example is illustrative copy, not a client result. Bracketed details are yours to fill in, and every one is written to be sent as-is to someone with documented consent.

1. Lapsed customer with a seasonal reason

Context: a customer from last year who bought a seasonal service.

Hi Ana, it's Luis from Peak HVAC. We serviced your furnace last October - our fall tune-up slots are open now. Want me to hold one before the rush?

Why it works: one line of history, one specific reason for the timing, one easy question.

2. Past customer due for repeat work

Context: service intervals, not a promotion.

Hi Sam, it's Dana at Northside Plumbing. Your water heater turns five this year - that's when we usually recommend a flush. Want a quote?

Why it works: it is service-shaped, not sales-shaped. The reason to reach out is genuinely theirs.

3. Old lead who never booked

Context: an inquiry from months ago that went quiet.

Hi Priya, it's Chris from Green Lawn Care. You asked about weekly mowing in spring - we have two route spots left for this area. Interested?

Why it works: it references the original ask, adds real scarcity that you can actually honor, and asks a yes-or-no question.

4. Stale quote with one useful update

Context: a quote from months ago, nothing pushy.

Hi Dan, it's Dana at Northside. The estimate for the fence repair we sent in June is still accurate on labor, and material prices dropped. Want an updated number?

Why it works: a discount you cannot justify is noise; a real change in the numbers is information. Only send this if it is true.

5. Value already paid for

Context: unused package, session credit or membership balance.

Hi Rachel, it's Bloom Aesthetics - you have two sessions left on your package from last year. They don't expire, and next week has good openings. Want one?

Why it works: it is a reminder of value they already own, which is the most welcome kind of reactivation message there is.

6. Return offer with an honest expiry

Context: a real deadline you will honor.

Hi James, it's Luis from Peak. Spring tune-ups are $99 through the end of March - after that it's $149. Want the 10am slot on the 28th?

Why it works: one fact, one consequence, one action. Fake urgency gets remembered alongside the report button; real deadlines do not.

7. The single follow-up

Context: no reply to the opener, four to seven days later.

Hi Ana, following up once - still want me to hold that tune-up slot, or should I close the file? Either answer is fine.

Why it works: it gives permission to say no, which is exactly why people reply. If there is no response to this, stop.

8. The clean exit

Context: still nothing after the follow-up.

Last note from me, Ana - I'll stop here. If the furnace needs us later, just reply and I'll pick it up. Thanks!

Why it works: it closes the loop honestly and leaves the relationship intact for a future, genuinely new reason to talk. This message often earns stragglers back.

9. When someone asks how you got their number

Context: a transparent reply, sent immediately.

You're on our customer list from your 2023 furnace service and you opted in to service texts. Reply STOP to opt out, or tell me and I'll remove you now.

Why it works: transparency defuses suspicion. If they say remove me, remove them - and do not send anything else.

What not to send

  • Anything without the business name in message one. If the recipient has to ask "who is this," you have already lost.
  • "We miss you!" with no reason, no history, and no specifics. This is the single most reported pattern in reactivation.
  • A shortened link as the only content. Scam-shaped, and carrier filters agree.
  • Multiple sends in the same week, or the same sequence repeated 30 days later on non-responders.
  • Any message sent outside 8am to 9pm local time, or to anyone on the suppression list.

A four-week test plan

  1. Week 1: pick one segment - past customers due for repeat work is the safest start - and confirm you have consent records for everyone in it.
  2. Week 1: write the opener and the follow-up, both under 160 characters, and register or verify your sending number.
  3. Week 2: send the opener on a Tuesday to Thursday, between 10am and 4pm in the recipient's time zone.
  4. Week 3: send one follow-up to non-responders. Track replies, bookings, opt-outs and complaints by segment.
  5. Week 4: review. If complaints are zero and replies are real, expand to the next segment. If opt-outs spiked, your segment was too cold or your copy too salesy.

A competent AI reactivation agent can run the segmentation, sending windows and stop rules for you, and the lead reactivation workflow or database reactivation workflow shows the mechanics. For contacts who reply but are not ready, the SMS nurture workflow keeps them warm without burning the list. The strategy behind the messages - segments, timing, stop rules - is covered in our reactivation playbook, and if your texts need to sit inside a broader sequence, the follow-up text examples library covers the non-reactivation moments.

Next step

Start with the segment where you have the cleanest consent records: past customers due for repeat work. Send ten opener texts by hand this week and watch what happens. If you want the segmentation, registration checks and stop rules built into a system that runs without you, map the flow through the six-step intake or book a call and bring your list counts.

FAQ

Why do businesses get reported for spam when texting old customers?

The common causes are texting without specific consent, sending too often, texting from an unregistered number, and copy that looks like a scam. Textmagic's 2025 survey of 1,800 consumers found 41% of ignored business texts were seen as irrelevant and 39% were ignored because the sender seemed questionable, so relevance and identity prevent more reports than clever copy ever will.

How do I text someone who has not heard from us in two years?

Only if you have documented consent that covers marketing texts, and lead with context: who you are, when you last worked together, and one specific reason you are reaching out now. If the consent record is uncertain, use email or a phone call instead until the person opts into texting.

How many reactivation texts should I send?

One opener, then one follow-up, then stop unless the person replies. Project Broadcast's analysis of over 170 million messages found reply rates drop sharply once non-conversational texts pass 160 characters, and unsubscribe rates rise with them. A short opener and a single follow-up beat a long sequence.

Do I need to register my number before a reactivation campaign?

Yes, if you send application-to-person texts over a standard 10-digit US number. US carriers require A2P 10DLC registration, and unregistered traffic gets filtered and charged additional carrier fees. Registration protects deliverability, which is the whole point: a message that is filtered before delivery cannot be reported or answered.
