Hi Team,
Is there any way to send auto reminders to the users? I have found the plugin which is paid but we don not want to use that approach.Please let us know if there is another approach you know.
Of course you can do it by yourself.
You may create a small script in php which queries the database by the API (or directly) and sends a reminder where necessary.
This script you call each day by a cron job. There are many providers for free cron jobs.

Volunteers are not paid.
Not because they are worthless, but because they are priceless
