What should I send to past customers? 7 emails that work?
Send past customers one clear, timely reason to come back: a friendly check-in, a seasonal reminder, a rebooking nudge, a helpful tip, an honest offer, a win-back note, or a thank-you with a referral ask. One idea per email, one easy next step.

Your past customers already trust you. They picked you once, paid you, and were happy. But every month you do not show up in their inbox, they drift a little closer to whoever shows up first on Google next time.
The good news: emailing past customers is the easiest marketing there is, because you are not selling to strangers. You are reminding people who already like you that you exist.
Below are the 7 emails that consistently work for service businesses — what each one says, when to send it, and a real example line you can borrow. If your trade has its own page, the industry guides go deeper.
Not best for
- Businesses trying to email contacts without permission.
- Teams that want to send private customer details in broad campaigns.
- Campaigns with no clear reason, offer, or next step.
1. The friendly check-in
The simplest email on this list, and often the highest-response one. No offer, no pitch — just a real note asking how things are holding up since your last visit.
Example: "Hi {first name}, it has been about six months since we were out. Is everything still working the way it should? Reply to this email if anything needs a look."
When to send: 3 to 6 months after a completed job. Why it works: it reads like a person, not a promotion — and replies land jobs.
2. The seasonal reminder
Tie the email to a real moment on the calendar: the first heat wave, the first freeze, spring cleanups, holiday hosting. The season does the selling for you.
Example: "Cold nights start next week — if your heater struggled last year, this is the week to have it checked."
When to send: 2 to 4 weeks before your busy season starts, before customers start searching.
3. The rebooking nudge
If your work repeats on a schedule — tune-ups, cleanings, groomings, pump-outs — say so plainly and make booking one click.
Example: "Most water heaters need a check every year. Yours is due. Grab a time here."
When to send: when the customer passes the due date for your service cycle. This is the email that turns one-time jobs into recurring revenue.
4. The helpful tip
Teach something small and genuinely useful. It keeps you remembered between jobs without asking for anything.
Example: "Three things your drains want you to skip this Thanksgiving: grease, potato peels, and coffee grounds."
When to send: any quiet month. One tip email between every one or two promotional emails keeps your list warm without wearing it out.
5. The honest offer
A real discount or bonus with a real reason and a real deadline. Past customers should get your best offers first — tell them that.
Example: "Past customers only: $40 off tune-ups booked this month. We would rather fill the schedule with people we know."
When to send: slow periods you can predict. Keep offers occasional — if every email is a discount, the discount stops meaning anything.
6. The win-back email
For customers you have not seen in a year or more. Acknowledge the gap, keep it warm, and make coming back easy.
Example: "It has been a while — how is the house treating you? If anything has been sitting on your list, reply and we will get you a time this week."
When to send: quarterly, to anyone 12+ months quiet. Our guide to reconnecting with old customers covers this one step by step.
7. The thank-you and referral ask
Two weeks after a job: thank them, make it right if anything is off, and ask for the referral while the good experience is fresh.
Example: "Thanks for trusting us with your home. If a neighbor needs the same help, we always appreciate the referral — and we treat your referrals like family."
When to send: 10 to 14 days after every completed job, automatically if you can.
How often should you email past customers?
Once or twice a month is plenty for most service businesses. The goal is to be remembered at the moment of need, not to fill inboxes.
A simple rhythm that works: one seasonal or promotional email, then one helpful or check-in email, repeating. Skip a send when you have nothing worth saying — silence beats filler.
Three rules that keep these emails welcome
- Permission first: only email people who agreed to hear from you, and make unsubscribing painless.
- One idea per email: one reason, one service, one button. Split anything bigger into two sends.
- Sound like your business: the same voice customers heard in person, not a marketing template.
Start with one email this week
Do not build a grand plan. Pick the one email above that matches this month — seasonal reminder in spring and fall, win-back in a slow week, thank-you notes always — and send it to the customers you already have.
If writing it is the part that stops you, that is the exact job MeSquared does: type the idea in one sentence, get the finished email in your brand, approve it, done.
Honest limitations
- The right email depends on the service, season, and customer relationship.
- Do not imply a customer needs a service unless you know that is true.
- Make unsubscribing easy and respect suppression lists.

FAQ
Questions owners ask.
What if I have not emailed customers in a long time?
Start with a friendly reintroduction and a useful reason to reconnect. Do not pretend you have been sending regularly.
Should I send discounts to past customers?
Sometimes, but not every email needs a discount. Seasonal reminders, useful tips, and appointment openings can also work.
How long should the email be?
Short is usually better. One clear reason, a few helpful details, and one CTA are enough for many service-business campaigns.
What is the best day to email past customers?
Midweek mornings are a safe start, but your own results beat any rule. Send, check opens and clicks, and adjust. Timing matters less than sending consistently.
Do these emails work with a small list?
Yes — better, actually. A list of 200 real past customers who know you will out-perform thousands of cold contacts every time.
