Can my system send travellers a reminder before their trip without my staff doing it?

Yes, reminders of that kind are a good fit for automation, because they follow a fixed pattern and depend only on the travel date already held against the booking. Once the system knows when a trip begins it can send a message at a set point before departure without anyone remembering to do it, and the same applies to a thank you note or a review request once the traveller is back.

What you can send depends on the channels you have set up. Email is usually the simplest, because the booking already carries an address. Text messages and messaging apps are possible too, but they need a separate provider account and, in some countries, an approved template before anything can go out, so it is worth checking those rules for the markets you sell to.

The wording is where care is needed. A reminder that repeats details the supplier may still change, such as a pickup time or a departure time, can create more calls than it saves, so many agencies keep the automatic message short and point the traveller back to their voucher or booking page for the latest position.

Start by listing the messages your staff send by hand today and note how often the details inside them change, because the steady ones are worth automating now and the changeable ones are safer left with a person.
