How to Build a Multi-Step SMS and Email Follow-Up Sequence
A message-by-message blueprint for a follow-up sequence that runs itself: timing, channels, what each message says, and how to test it.
Most advice about follow-up sequences stops at "you should have one." That's not useful. You need to know what each message says, when it fires, which channel it uses, and what happens when a lead does something unexpected.
So here's the whole thing. Build this over a weekend and you'll have follow-up that outlasts your motivation.
Before you write a single message
Three decisions, and they take five minutes each.
One: what counts as a lead. Form fill? Missed call? Someone who texted your business line? Pick every entry point you actually have and write them down. If a lead can get into your business through a door you didn't list, it's going to fall on the floor.
Two: what "success" means. Not "a reply." Be specific. It's usually one of: a booked call, a scheduled estimate, a signed quote. That's your finish line. Every message in the sequence points at that one thing, not at seven different things.
Three: what stops the sequence. Any inbound reply. Any answered call. Any booking. Any opt-out. Write this down now, because it's the thing people forget and it's the thing that torches your reputation when it breaks.
The sequence, message by message
Times are from the moment the lead enters. Adjust for your business, keep the structure.
Message 1 — SMS, within 5 minutes
Hey Dana, it's Chad at Gardner Plumbing. Got your request about the water heater. Are you looking to replace it or just get it looked at first?
What it does: proves a human is on the other side, and asks one question with a short answer. A question they can answer at a stoplight. Never lead with "we'll get back to you shortly," because that message asks for nothing and gets nothing.
Never send a novel by text. Two sentences and one question mark.
Message 2 — Email, about an hour later
Subject: Your water heater — what to expect
Body: three short paragraphs. What you do. A realistic price range with the reason it's a range. What happens next if they want to move forward, including the booking link.
Why an hour later: it doesn't crowd the text, and it catches the people who prefer to read rather than reply. Email also does something SMS can't do well, which is carry detail without feeling long.
Message 3 — SMS, next morning
Morning Dana. Still want me to get you that number on the water heater? Happy to just text it over.
Short. Low pressure. Note that it offers to do the work for them rather than asking them to do work.
Message 4 — Email, day 3
This is the one that isn't about you. Pick the question your customers always ask and answer it properly. "Repair or replace: how to decide." "The three things that should be on any estimate." "Why the cheapest quote usually isn't."
You're not selling here. You're being the person who knows things. It earns the right to ask again on day 6.
Message 5 — SMS, day 6
Dana, easiest thing is 10 min on the phone and I can give you a straight answer. Any slot here works: [booking link]
The booking link matters. "Let me know a good time" makes them do scheduling work. A link makes them do one tap. More on that in a second.
Message 6 — Email, day 10
Address the objection directly. Not coyly. If people hesitate on price, say so: "If the number's higher than you hoped, tell me. There's usually a version of this that fits a smaller budget, and I'd rather build that than have you do nothing."
That kind of message gets replies from people who have been quietly embarrassed about the price for a week and a half.
Message 7 — SMS, day 14
Dana, I'll stop filling up your phone. If the water heater becomes a problem again, text this number and I'll pick it right back up. Good luck either way.
Then stop. Fully. The graceful exit is what earns the reply, and when it doesn't, it's what keeps you welcome in 60 days.
The rules that make it work
Alternate channels. Never two SMS in a row without an email in between, and never two of anything on the same day past day 0. Alternating makes the cadence feel like a relationship instead of a drumbeat.
One idea per message. If a text has two questions in it, it gets zero answers.
Write like you talk. Read every message out loud. If you'd never say it to a person standing in front of you, rewrite it. "We wanted to circle back regarding your inquiry" is not a thing a human being says.
Personalize the one thing that matters. Their name and what they asked about. That's it. Nobody is impressed by merge fields. Everybody notices when you remember it was the water heater.
Signature stays constant. Same name, same number, every message. You're building the feeling of one person, not a marketing department.
Wiring the stop condition
This is the part that separates a system from an embarrassment.
Your sequence must be cancelled by:
- An inbound SMS from that number
- An inbound email reply
- An answered outbound call, logged
- A booking on your calendar link
- Any manual mark of "won" or "lost"
- An opt-out keyword (STOP, and honor it instantly)
If your tools can't do all of those, get as many as you can and cover the rest with a daily 60-second habit: open the queue, scan for anyone you talked to, kill their sequence by hand.
The failure mode you're protecting against is specific and it is brutal. You have a great phone call, you shake hands, and then Tuesday morning a robot texts them "just checking in about your water heater!" Now you look like a company that doesn't know what its own left hand is doing, and they wonder what else you'll drop.
Test it on yourself before it goes near a customer
Enter yourself as a lead. Real phone, real email. Let the whole sequence run in fast-forward if your tool allows it, real time if it doesn't.
Read them in order on your actual phone. Not on a desktop preview. On the phone, in the thread, the way a customer will.
Then run the abort test. Enter yourself again and reply after message 2. Wait. Confirm nothing else arrives. If anything shows up, you're not done.
What you'll notice in the first month
The first thing owners notice is not the extra jobs. It's the replies that come in on day 6 and day 10 from people they'd already written off. That's the moment the whole idea clicks, because you're watching money walk back in the door from leads you had already grieved.
If you want the sequence built, tested, and wired into whatever you already use, without turning it into a six-week project, that's the work. Nothing fancy. It just has to run every time and stop when it should.
Send me what your current follow-up looks like and I'll tell you the two changes I'd make first.
