Is Remindlo a ClickSend alternative?

Yes, for the appointment reminder use case. ClickSend is a multi-channel messaging API for developers; Remindlo is a managed product specifically built for SMS reminders, recurring services, and customer reactivation.

Does Remindlo have its own SMS API?

Yes. The REST API at api.remindlo.co.uk supports contact and campaign management, and the MCP server at mcp.remindlo.co.uk works with Claude AI.

Can I keep using ClickSend for marketing and Remindlo for reminders?

Yes. Many teams keep an SMS API for one-off integrations and use Remindlo for the recurring appointment-reminder workflow. The two are complementary.

How does Remindlo handle deliverability?

Remindlo routes SMS through Twilio for non-North-American numbers and Telnyx for +1 numbers, with automatic provider fallback if one of them errors.

Can I import my ClickSend contacts?

Yes. Export contacts as CSV from ClickSend and import them into Remindlo. Phone numbers need to be in E.164 format.

Is multi-channel (voice, MMS, post) on the roadmap?

Remindlo focuses on SMS and email reminders today. Voice messaging is a planned channel. If you need fax or physical post, ClickSend is a stronger fit.

Why teams pick Remindlo over a raw SMS API

ClickSend gives you SMS, voice, MMS, and post in one API. Useful for engineering teams. Painful when the goal is reminding customers about their next visit.

A product, not a toolkit

ClickSend gives you the SMS pipe. Remindlo gives you contacts, campaigns, calendar sync, recurrent dates, and templates already wired together.

Calendar to SMS without scripting

Connect Google Calendar in Remindlo and appointments become reminders automatically. With ClickSend you write the integration yourself.

Predictable monthly billing

Bundled SMS in paid plans and a free tier remove the surprise bills that come with high-volume pay-as-you-go reminders.

What Remindlo adds on top of raw SMS

Three layers turn an SMS pipe into a working reminder product.

Customer records with next-due dates

Contacts track the next service date, consent, last visit, and recurrence rule. The data model is the reminder.

Scheduled campaigns

Define when reminders fire (days before the appointment, recurring intervals, after the visit) and Remindlo runs them on time.

Two-way replies that update the record

STOP, START, and free-text replies flow back into the dashboard and adjust consent state automatically.

Recurring MOT reminder

Hi Tom, your MOT at North Garage is due in 14 days.

Migration

Moving from ClickSend takes about an hour

If you currently send reminders by calling the ClickSend API from a script or spreadsheet, you can replace it with a Remindlo campaign in minutes.

1
Export your contact list
Pull contacts and next-due dates from your script, CRM, or spreadsheet into a CSV. Use E.164 phone format (+44...).
2
Import into Remindlo
Drop the CSV into the bulk importer. Map columns to first name, phone, next-due date, and tags.
3
Replace your sending script with a campaign
Pick a template, set the cadence, switch it on. The cron-style logic now runs inside Remindlo.

Works with your calendar

Connect Remindlo to Google Calendar and turn scheduled appointments into automatic SMS reminders. No CSV uploads, no scripting.
