Right now you have no viable options for setting up automated meeting reminders for our clients. Please do not tell me about Appointment Reminders (your only current integration for sending meeting reminders to clients). That product is woefully inadequate and the customer support is lacking.
Apptoto is a fantastic product, with strong customer service. A direct integration with Redtail would be a fantastic service to provide. This is a no-brainer. Please get it done.
As it is now, we can use Apptoto with an indirect connection that depends on the reliability of Retriever Cloud. Therein lies the problem, Retriever Cloud connections break on a regular basis.
Please, please, please work with the Apptoto team to develop a direct integration! Thank you.
