SMS Follow-Up for Leads: Cadence, Scripts and When to Stop

Most SMS follow-up fails in one of two ways. It sends one message and gives up, which wastes the lead you paid for. Or it never stops, which trains people to block you and eventually gets your number filtered by the carriers.

An SMS follow-up cadence runs about ten touches over thirty days, spaced seconds, minutes, hours, then days, then a week apart. Each message asks one question, sends between 8 a.m. and 9 p.m. in the lead's time zone, and stops on a booking, a no, or the last touch.

The consent and carrier registration underneath all of it is settled before the first message goes out, not after.

This is about following up on leads who opted in. The specific case of texting someone back after a missed call is covered in missed call text back, and the mechanics of carrier registration are in A2P 10DLC registration. This piece is the cadence itself.

The floor, before anything else

None of what follows works if this part is wrong, and the penalties run from carrier filtering to statutory damages.

Consent comes first. Marketing texts to a wireless number need prior express written consent under the Telephone Consumer Protection Act. In practice that means a disclosure on the form the lead filled out, a record of which version they saw, a timestamp, the source page and the number. Keep those in your own system, not only in a vendor's.

You have to be registered. US business texting to local 10-digit numbers requires A2P 10DLC brand and campaign registration. It has carrier fees and an approval wait, and your sample messages have to match what you actually send. Start it weeks before you need it.

Quiet hours are a hard edge. The FCC's rules at 47 CFR 64.1200 bar telephone solicitations before 8 a.m. or after 9 p.m. in the called party's local time. Treat that as the floor and use the lead's time zone, not yours. An 8 p.m. text from Los Angeles arrives at 11 p.m. in Boston.

Identify yourself in every message. Not just the first. Someone who gets a text three weeks later should know in the first four words who it is from.

Honor opt-outs immediately. STOP, UNSUBSCRIBE, "take me off this list" and anything a reasonable person means as stop. Do not require an exact keyword. The FCC's rule setting an outside deadline for processing revocation has been amended and delayed more than once, so have your compliance officer confirm the current requirement rather than relying on anything written a year ago. Immediately is the only setting worth running anyway.

Carriers have their own rules. The CTIA Messaging Principles and Best Practices (May 2023) is the industry standard the carriers apply, and section 5.1 asks that messaging operate consistent with the TCPA and FCC consent rules regardless of whether those rules technically apply. Carriers do not need a court to filter you.

If the list is old rather than fresh, run the consent check before anything sends; the method is in database reactivation. And if someone is suggesting you text a purchased list, that is a different activity with different law attached. It is not one we run.

None of this is legal advice. Confirm your setup with your own counsel. Our SMS terms show the language that governs our texts.

The cadence

Ten touches over thirty days. The spacing matters more than the count: tight at the start, because that is when they are thinking about it, and widening fast, because a daily text in week three is harassment.

The timings below are a working shape, not a benchmark. Adjust for your sales cycle: a roofing leak is a same-day decision, a mortgage refinance is not.

Touch 1 is the whole game. Harvard Business Review's audit of 2,241 US companies found firms that reached a lead within an hour were nearly seven times as likely to qualify it as firms that waited an hour longer, and more than 60 times as likely as firms that waited a day. The full research, and the parts of it that get misquoted, are in speed to lead statistics.

Touch 8 is the one most sequences leave out, and it is usually the second-highest producer in the whole series. People answer a direct question.

What each message should actually say

Six rules that matter more than the wording.

One question per message. Two questions get zero answers. The question should be answerable in one word where possible: a time, a yes, a number.

Identify, reference, ask. Who you are, what they did, one question. "Hi Dana, it's Mike at Harbor Roofing. You asked about the leak on Oak Street. Is water still coming in?" Three clauses, under 160 characters, and it is obvious why they are hearing from you.

No links in the first message. Public shorteners get filtered hardest, and a cold link from an unknown number reads as spam to both the carrier and the person. Earn the reply first, send the link second.

Never "just checking in." It asks nothing, offers nothing and signals that you have run out of things to say. Every message should carry one new piece of information or one new question.

Write like a person texting, not a brand broadcasting. Lowercase is fine. One sentence is fine. A paragraph is not, and neither is an emoji wall.

Change the angle, not the volume. If three messages have not landed, the fourth should not be the same ask in bold. Try a different question: what is holding it up, what would need to be true, who else is involved.

A sketch of the arc, with the wording left for you to make yours:

Touch 10 is worth writing properly. A clean exit gets more replies than touch 9 does, and it leaves the relationship intact for the reactivation campaign in six months.

Timing windows

The hard edge: 8 a.m. to 9 p.m. in the lead's local time. Derive the time zone from the area code or the address, and do not trust the default on whatever tool is sending.

The practical window: most teams see better reply rates from mid-morning and early evening than from the middle of the afternoon. Treat that as a hypothesis for your own list rather than a fact about texting, and test it with your own numbers.

Touch 1 ignores all of this, because it is a response to something the lead just did. If they fill out a form at 11:40 p.m., an immediate reply is what they expect. Whether that falls inside your quiet-hours policy is a question for your counsel, and the conservative setting is to queue it for 8 a.m. with an immediate auto-acknowledgment at the point of submission on the page itself.

Avoid the obvious dead zones: early Monday, late Friday afternoon, and the day of a major holiday. These cost you nothing to skip.

When to stop

Three stop conditions, and all three should be wired in before the first message sends.

They opt out. Immediately, on any phrasing, across every sequence and every number you own. A person who said stop for the sales sequence should not receive the newsletter.

They book, buy or say no. The sequence should end the moment the outcome arrives. Nothing destroys trust faster than a nudge about booking a call that arrives after the call. This is a wiring problem more than a policy one: the sequence has to be watching the calendar and the CRM, not just the clock.

The cadence runs out. After touch 10, stop. Tag the record, and put them into a slower, clearly different channel if they opted into one. Do not restart the same sequence in sixty days and hope nobody notices.

One more that people miss: stop when the replies stop making sense. A lead replying with single characters, or in a way that suggests a wrong number or a confused person, is a hand-off to a human, not a prompt for touch 6.

Where AI changes this, and where it does not

A drip sequence sends. An AI agent has a conversation, and the difference shows up in exactly one place: the reply.

Most SMS follow-up dies because someone answers touch 3 at 9 p.m. on a Saturday with "what would that cost?" and nobody reads it until Monday. By then the person has moved on. The cadence was fine. The response to the response was not.

What an agent should do with an inbound reply: answer the question if it knows, offer real times from your actual calendar, write the booking into your CRM, stop the sequence, and hand off to a person the moment the question goes outside what it knows. Agents we build on StrideOps respond in under 2 seconds, day or night, and hand off rather than guess.

What it should not do: argue about price, pretend to be a specific employee, keep pushing after a soft no, or improvise a claim about your service. The seven questions to ask any vendor about exactly this are in how to choose an AI appointment setter.

Once an appointment exists, the job changes from booking to protecting it, which is a different cadence; that one is in how to reduce appointment no-shows.

What to measure

Five numbers, and the first two are the ones that tell you whether to change the messages or change the timing.

Watch opt-outs per touch rather than overall. An opt-out rate that is fine on average can be hiding one message that burns 4% of your list every time it sends.

FAQ

How many times should you follow up with a lead by text?

Around ten touches over thirty days works for most businesses, spaced tight at the start and widening fast. The spacing and the stop conditions matter more than the count: the first hour does most of the work, and the sequence has to end cleanly rather than loop.

What should the first follow-up text say?

Identify your business, reference what they just did, and ask one question they can answer in a word. Keep it under 160 characters with no link. "Hi Dana, it's Mike at Harbor Roofing. You asked about the leak on Oak Street. Is water still coming in?" does all three.

What time can you legally text leads?

FCC rules bar telephone solicitations before 8 a.m. or after 9 p.m. in the called party's local time, so use the lead's time zone rather than yours. Carriers apply their own standards through the CTIA Messaging Principles. Confirm your policy with counsel.

How do you stop an SMS sequence correctly?

Wire three stop conditions before launch: any opt-out phrasing stops everything immediately, a booking or a stated no ends the sequence at once, and the cadence ends itself after the last touch. The common failure is nudging someone who already booked.

Can AI handle SMS follow-up for leads?

AI earns its place on the replies rather than the sends. Any scheduler can send touch six on day four. The value is answering someone who replies at 9 p.m. on a Saturday, offering real calendar times, writing the booking to your CRM and ending the sequence.

Do I need A2P 10DLC registration to text leads?

Business messages to US local 10-digit numbers require A2P 10DLC brand and campaign registration. It carries carrier fees and an approval wait, and your registered samples must match what you send. Our A2P 10DLC guide has the details.
