Start with accurate vehicle records
Reminders sent against out-of-date records annoy customers. Vehicle details and MOT status should come from the record you created at the job, not a separate spreadsheet.
Mozomay shows MOT status and due dates against the vehicle where they are available.
Timing and tone
Three to four weeks out is usually enough notice for the customer to book a convenient slot and for you to fill the diary.
Keep the message short: the vehicle, the due date, and how to book.
Consent and data
UK marketing rules apply to reminder messages. Record how you obtained consent and make opting out simple.
