Email or SMS Marketing? How to Choose for a Local Business
Email suits longer messages, newsletters and customers who like to read; text messages suit short, time-sensitive reminders and are read quickly. A UK guide says industry data shows SMS outperforming email on engagement, while email has well-known benchmarks. Both are regulated, need consent and an opt-out, and work best when you use each for what it does well.

When email fits
- A welcome message when someone signs up.
- A monthly tip or update.
- Anything that needs links, images or more than a few lines.
- Sequences that run on their own, such as a thank you, a review request and a reminder.
See email marketing for local businesses for a plan.

When SMS fits
- Appointment reminders and confirmations.
- A short message about a time-limited slot.
- A quick check that a job went well.
A UK guide notes that SMS reaches almost everyone with a phone and warns that it can backfire if it feels intrusive. Keep texts rare, relevant and clearly from you.
Use a simple mix
Many local businesses use both: email for useful information and sequences, and text for reminders. Start with whichever your customers prefer, using your own data, and measure enquiries and unsubscribes.
The rules apply to both
Marketing emails and texts to individuals generally need consent, with a limited exception for existing customers, and every message needs an easy opt-out. See UK rules for emailing and texting customers for the points to check, and take legal advice.
How to choose in four steps
- Ask your customers which they prefer, and record consent for that channel.
- Pick one channel and one useful message type, and run it for three months.
- Measure replies, bookings and unsubscribes.
- Add the second channel only if the first works and you can keep up.
Frequently asked questions
Is SMS better than email for small businesses?
A UK guide says industry data shows SMS outperforming email on engagement, but email costs little and suits longer messages. Many businesses use both.
Do I need consent to text customers?
For marketing texts, generally yes, with a limited exception for existing customers. Check the rules and take legal advice.
Can I text customers about an appointment?
A message about an appointment they booked is different from a marketing message. Keep it to the booking, and check the rules for your case.
How often should I send texts?
Rarely. Use them for reminders and short, relevant messages, and watch opt-outs.
What does SMS marketing cost?
Usually a per-message charge plus a platform fee. Ask your provider for prices in pounds.
