Is anyone using an automated communication tool?

[Michael Greenberg]

As I continue to grow I am starting to feel some growing pains, or I guess it's more just "a pain I don't want to deal with as much anymore".  I send the following messages:  Booking confirmation and request for email address, email directly the House Guide, pre-arrival details, follow up email during the stay, and a thank you.  I would like to add a check out reminder message but that means 6 manual messages for each booking - UGH!  Anyone have experience with AirGMS (looks like it works well but the dashboard lacks intuitiveness) or something similar?  Could a tool like IFTTT work if configured somehow?  I would prefer to keep the communication within the booking platform but if there's a better way I'm all ears.

Thanks!
