A customer books, the job gets done, the invoice gets paid. Then, for most service businesses, silence. Months later the customer needs something and either remembers you or searches Google and picks whoever ranks first.

The gap between the invoice and the next need is where a customer relationship is formed or not. Filling it takes a handful of emails, written once and sent automatically. This is the sequence, in order, with the reasoning behind each message.

Why the first 90 days

The customer has just had a direct experience of your work. Their attention is highest, their opinion of you is fresh, and the reasons they might refer or rebook are specific. Ninety days later the memory has faded into "some plumber." The sequence works while the memory is sharp.

It is also the window in which the customer's judgment is being formed. A customer who hears from you three times in a helpful, non-salesy way in the first quarter has a very different sense of the business than one who hears nothing until a promotional blast in six months.

Message 1: the day after, the thank-you and the check-in

Sent the morning after the job. Plain text, from the owner or the technician by name. Thanks for choosing us, here is what we did in one sentence, here is what to watch for over the next few days, and reply to this email if anything is not right.

That last line is the important one. You want the unhappy customer to reply to you before they write a review. This message is where problems surface privately.

Message 2: day three to five, the review request

If no reply came to message one, or the reply was positive, the review request goes out. Short. A direct link to your Google review form, one sentence on why it matters to a small business, and nothing else. The mechanics of getting that link and making it work are in our guide to a review QR code and short link.

Do not condition anything on the rating, and do not route unhappy customers to a private form while sending happy ones to Google. That is review gating, and it breaks both Google's rules and the FTC's.

If the customer already left a review, this message is skipped. Your CRM should know.

Message 3: day ten to fourteen, the useful follow-up

This is the message most businesses never send, and it does the most work. It is not a sale. It is one piece of genuinely useful information related to the job you just did.

For an HVAC tune-up: how to read the filter and when to change it. For a plumbing repair: what a running toilet costs and how to spot one. For a cleaning service: how to keep the kitchen looking like it did on the day. For a roof repair: what to check after the next storm.

One topic, a few short paragraphs, a photo if it helps. The point is to be the business that helped after the money changed hands. It earns the next message.

Message 4: day thirty, the referral ask

Now the customer has heard from you three times, none of them pushy. This message asks for one thing: if you know someone who needs this, here is how to send them to us. If you run a referral program, this is where the terms go. If you do not, a simple "forward this email" with a booking link works.

Keep it to a few sentences. The referral ask lands because of the three messages before it, not because of the copy.

Message 5: day sixty to ninety, the next-service prompt

The last message in the sequence is the first one that sells, and it sells the specific next thing this customer is likely to need. That depends on what you did:

After a repair, the maintenance plan or the seasonal check.

After a one-time cleaning, the recurring schedule.

After an installation, the first service interval.

After a seasonal job, the other season.

If your services do not have a natural next step, this message becomes a short "here is everything else we do" with the one or two services most customers do not know you offer. Maintenance agreements are the strongest version of this for the trades, and we covered why in maintenance agreements and recurring revenue.

After message 5, the customer moves into your regular cadence: a monthly or seasonal newsletter, and the win-back sequence if they go quiet for a year.

Setting it up

The sequence is triggered by one event: the job is marked complete, or the invoice is marked paid, in whatever system you use. Each message has a delay from that event and a condition (skip the review request if a review exists; skip the next-service prompt if they already booked it).

This lives naturally in a CRM. If yours cannot trigger on job completion, or cannot see whether the customer replied or booked, that is a limitation worth fixing, and it is the kind of thing a managed CRM build-out exists to solve.

Write every message in plain text, from a person's name, with a real reply-to address that someone reads. Formatted newsletters have their place; this is not it.

The sequence is a standard part of the email and SMS programs we run for home service clients.

Frequently asked questions

Should any of these be text messages instead?

The review request works well as a text, especially if the customer booked by text. The others are better as email, where there is room to be useful. Make sure you have the right consent for whichever channel you use.

What if the customer replies to message 1 with a complaint?

Pause the sequence for that customer and handle the complaint personally. Resume only after it is resolved, and skip the review request unless they volunteer.

Is five messages too many?

Spread over ninety days, with four of the five giving rather than asking, no. Customers unsubscribe from noise, not from help.

How do I know it is working?

Track review rate, referral rate, and rebooking rate for customers who went through the sequence versus those who did not. Start the sequence, measure for a quarter, then adjust the messages that underperform.
