Start with the messages that protect revenue you already have: appointment reminders, a text back when you miss a call, and a follow-up for people who asked about a quote and went quiet. Add review requests and offers to past customers after that. Get consent before you text anyone, include an easy way to opt out, and approve every message before it goes live.
Why automate email and SMS at all?
Because the follow-up that matters most is also the easiest to forget on a busy week. A Cochrane review of eight randomized trials found that text reminders improved attendance at healthcare appointments:
The reminder figures come from healthcare, so treat them as a direction for any business that takes bookings, not a promise. The same review found text reminders worked about as well as phone calls, and once they are set up, they take nobody's time.
What should you automate first?
Start where a missing message costs you a customer you already had, then work outward:
Appointment reminders
If you take bookings, start here. A text the night before catches the people who simply forgot.
Missed-call text back
When you cannot pick up, a text straight away tells the caller you saw it and gives them a way to book, instead of leaving them to call the next business on the list.
Enquiry follow-up
People who asked for a quote and went quiet are some of the warmest leads you have. A short follow-up or two is enough, then stop. More on how fast to respond to a lead.
Review requests
Ask every customer after every visit, not only the happy ones. Here is how to get more Google reviews within the rules.
Win-back and offers
Once the essentials run, email the customers you have not seen in a while. Keeping a customer usually costs far less than finding a new one.
Should you use text or email?
Use text for anything short and time-sensitive, and email for anything with detail:
| Text works best for | Email works best for |
|---|---|
| Reminders the day before | Offers, news and seasonal campaigns |
| A missed call or a same-day change | Anything with details, photos or links |
| A quick nudge on an open quote | Win-back messages to past customers |
Texts feel more personal, which cuts both ways. Keep them short, rare and useful, and save the longer messages for email.
What rules do you need to follow?
A few, and they are worth getting right before the first message goes out:
- Get consent before you text anyone, and keep a record of it
- Give every message an easy way to opt out, and stop when someone does
- Honor email unsubscribe requests within 10 business days
- Include a valid physical postal address in every marketing email
- Keep subject lines honest, and say clearly when an email is an ad
- Register your business texting through a messaging provider before you send
The email rules come from the FTC's CAN-SPAM guide, and they apply to marketing emails sent to existing customers too. For texting, businesses sending from a standard 10-digit number are verified through The Campaign Registry before they can send, and that registration goes through your messaging provider. This is general guidance rather than legal advice.
How do you keep automated messages from feeling robotic?
Write them the way your front desk would talk. Use the customer's name, mention the actual appointment or service, and give each message one job. Send at sensible hours, and make sure a sequence stops the moment someone books or replies, so nobody gets a reminder for something they already did.
Test every automation yourself. Book an appointment, miss your own call and fill out your own form. You will catch broken links and awkward timing before your customers do.
Frequently asked questions
What is the difference between transactional and marketing messages?
A transactional message confirms something the customer already did, like a booking or a purchase. The FTC treats those emails as exempt from most CAN-SPAM rules, but only while they stick to that purpose. Add a promotion and the message can count as marketing.
How often should you text customers?
Only when there is a reason: a reminder, a missed call, or something they asked about. Keep promotional texts rare and planned, and let email carry the regular updates.
Do I need special software?
You need a platform that can send texts and emails, connect to your booking system and handle opt-outs and carrier registration. Some booking systems include basic reminders, which is a fine place to start.
Can automation replace calling customers back?
No. It handles the routine messages, so your team has time for the conversations that need a person.
