You can! Watch this Tutorial that Adalo Team created : https://youtu.be/UZEENzF6bHE
And also there are some more tutorials that send emails through different tools!
In past days I was using a form and added a custom action and it sometimes works but sometimes no. Then I tried to use Custom forms and seems like it’s working. Not sure if this is a bug or the limitation is still there that I posted above.
I have to ask it from the Adalo Team!
And in your Custom action for what email the information is sending? Could you add some screenshots?
Edit :
Ben from Adalo Team said :
This is still correct. Your best option is to use a custom form, or an interstitial screen to run the action if you don’t need to output.
Thank you
