For customers who prefer text to email — or who have stopped checking email — PoolStamp can send a short SMS after each visit with a link to the full receipt. The link opens the customer portal where they can see the photos, chemicals, and repair items.
Enabling SMS
SMS is account-wide opt-in for the launch product. In the web admin, go to Account → Notifications → SMS and toggle it on. PoolStamp uses Twilio under the hood — no separate Twilio signup on your side. If the SMS toggle is grayed out for your account, message support so we can finish enabling Twilio on the server side for you (one-time, typically same-business-day).
Once SMS is enabled, the visit completion flow checks each customer's phone field. If a phone number is present and properly formatted, an SMS is sent in addition to the email.
What the SMS contains
The message is intentionally short — under 160 characters whenever possible — and includes:
- Greeting with the customer's first name in their language
- A line confirming who serviced the pool
- A short link to the visit detail in the customer portal
That's it. We don't send chemical lists or photos in the body; the link delivers the full detail.
Phone number format
PoolStamp accepts US phone numbers in any common format (555-123-4567, 5551234567, +15551234567) and normalizes them internally. International numbers should be entered in E.164 format with the country code prefix.
If a number can't be normalized to a valid E.164, SMS is silently skipped for that customer.
Costs
Twilio SMS costs are bundled into your PoolStamp subscription for the launch product — there's no per-message charge to you. If your sending volume gets unusually high (>5,000/month), we may reach out about a pricing adjustment.
Disabling SMS for one customer
To opt a specific customer out of SMS while keeping email on, set their phone field blank or clear it. There's no separate "SMS opt-out" toggle in the launch product.
