The automatic maintenance reminder: what your memory will never do for 800 customers.

An automatic maintenance reminder is an email that goes out in your name, at the right time, because a unit you installed is reaching its due date — without anyone thinking about it. It is not a newsletter, nor a campaign: it is an individual message, triggered by a date, with a link to book. The difference with “I do my own reminders” comes down to one question: how many did you send last year, out of how many installations due?

What triggers a reminder

• The unit's cycle: twelve months after the last service for a heat pump or a furnace, two visits a year for a pool, an annual flush for a tankless water heater.
• The season: before the heat waves and before the deep cold, when the customer has the unit in mind.
• The warranty: as a warranty end approaches, or thirty days after installation to remind them to register the manufacturer warranty.
• End of life: at 12-15 years, the reminder becomes a replacement proposal — before the customer shops around.

What a good reminder looks like

Short, signed by your company, written in the customer's language, with a service argument rather than a sales pitch: “your warranty requires documented maintenance”, “your unit is four years old, the annual service protects the compressor”. One button: book a slot. The customer clicks, picks morning or afternoon, and it is confirmed on both sides — no account, no app. We publish a complete, free template, with the text-message version and the sending calendar.

The frequency that gets replies (and respects the law)

An effective reminder is rare. By default, Byrsia sends no more than one solicitation email every seven days to the same customer, stops the sequence as soon as the customer books or the service is marked done (a first reminder, then — from the Professional plan up — at most two follow-ups), and puts a one-click unsubscribe link in every message. That is what Canada's anti-spam law (CASL) asks for an existing business relationship — and above all it is what makes your customers open the second email. Every send is logged: sent, held, failed, and why.

What it changes in practice

The reminder goes out without you; the customer books online; the appointment appears in your calendar, where you assign it to a technician; the completed service is noted on the unit's record, which schedules the next reminder twelve months later. The loop closes by itself — and the dashboard shows what the reminders brought in, in dollars, not impressions.
