What Does an SMS Reminder Really Cost?
Published on 7/8/2026
The invisible line item
Every appointment-based business sends reminders — a text the night before, a nudge the morning of. It feels like a "free" feature bundled into whatever software you already use. It isn't. Most booking platforms send those texts through a third-party SMS gateway, which charges for every single message sent.
At a typical rate of €0.05–0.10 per message, a busy salon sending a few reminders a day quietly racks up €1,800–3,600 a year — a cost that never shows up as a single line, just a slow drip on a card statement.
As we wrote in a previous piece on the real cost of phone bookings, the pattern repeats: the "it's basically free" tools rarely are — the cost just moves somewhere harder to see.
A one-time cost instead of a per-message one
yAppointment's SMS App works differently: a one-time €150 purchase installs on the business's own Android phone and sends reminders through that phone's existing SMS plan. If that plan includes unlimited SMS, there's no additional per-message cost after the one-time purchase. (If your plan doesn't include unlimited SMS and bills per message instead, normal carrier charges still apply — the saving depends on the plan, not on the app itself.)
Compared to a typical pay-per-message SMS service, the break-even is usually 2–6 months — after that, the reminders that used to bill per message cost nothing extra.
And the reminders themselves pay for more than the messaging: automated SMS/email reminders cut no-shows by up to 70%, which is where the real savings usually show up — not in the SMS bill, but in the appointments that no longer go empty.
