How to email your customers? (Small business guide)
In a small business, the cheapest sales channel is the customer list you already have. Finding new customers costs advertising; emailing an existing one takes one afternoon. This guide explains three email types, when to send them, and what to write.
Permission first
Only email people you have a relationship with: those who bought, booked, filled a form. Mailing purchased lists is both ineffective and a legal/reputation risk. An unsubscribe option must appear in every message.

Three email types
1. Welcome (first touch)
Sent when a new customer signs up or after their first purchase. Purpose is relationship building, not selling: who you are, how to reach you, what to expect next.
Details: Send a welcome email
2. Campaign/announcement
New product, season, special day, capacity announcement ("holiday orders close the 20th"). Keep to 1–2 per month; frequent email kills subscriptions.
Details: Email your customers
3. Win-back
To customers who haven't been seen in a while. Highest ROI send — they already know you. Keep it short, personal, single call-to-action.
What to write? (skeleton)
- Subject line: clear and short. "Holiday orders open" > "Hello!"
- First sentence: why you're writing
- One message: one email, one goal
- One button: "Order now", "Book appointment", "View menu"
- Signature: real name and contact — small business strength is personal
Avoid: long paragraphs, three different campaigns, "Dear valued customer" tone.
How to choose who to email?
If you keep customer records, a list already exists: those who ordered, booked, messaged. If you have an old Excel, you can import it.

Frequency
| Type | Frequency |
|---|---|
| Welcome | Once, triggered |
| Campaign/announcement | 1–2 per month |
| Win-back | Every 2–3 months, to selected people |
| Payment reminder | Based on deadline, as needed |
Payment reminders are separate: Send a payment reminder
Measurement
Three numbers matter: opens, clicks, orders/bookings after send. The third is the real one; track from site analytics.

Common mistakes
Same message to everyone. A new customer and a two-year customer shouldn't read the same thing.
Only discounts. Discount brings discount seekers; include info and story.
Ignoring subject lines. An email no one opens is an email not written.
Sending too often. For small business, once a week is usually too much.
