Remindlo
Remindlo sends SMS reminders before booked visits and when a service is due again. It is aimed at owner-run and small-team service businesses with returning customers, including garages, dental practices, salons, vets, and trades. After visits, it can send thank-you notes, review requests, and win-back messages. Remindlo connects to Google Calendar, Outlook, and iCloud, turning bookings into contacts with reminders; it can also scan a photo of a paper diary to extract names, dates, and phone numbers. An AI model reads names from calendar entries and leaves the name blank when it cannot identify one. Customers can confirm or reschedule by text, and opt-outs are removed automatically. Integrations listed include Calendly, Cal.com, Acuity Scheduling, Square Appointments, Google Sheets, Zapier, and Claude AI. Its REST API supports contacts and campaigns, while webhooks report delivery with signed payloads and automatic retries. The free plan includes 10 SMS monthly and limited email sending. Starter costs £19.00 per month and includes 75 SMS monthly, unlimited emails, the SMS Message API, basic analytics, and email support. Free-plan users cannot buy SMS top-ups.
