Hi! Can I make an user updating data by an e-mail to the system and not directly by a form?
YES you can! Off the top of my head, I can think of a few different ways. First, check out the zapier integrations here:
Next.. you can “roll your own” if you have a server where you can write your own SMTP listener and use the Ninox REST/API.
Both require that you have a Ninox Cloud account
Wow.. google snuck this one by me..
Looks like you will have to pay for a google business account for this to work. :(
