How to send the welcome & onboarding email when the user sign up?
Hi, I would like to help you with your question.
If you already have a login page similar to this it is easy to send an automactic email to a new logger:
In that case go to the workflow of the sign up button and insert the following action:
Then it is important to fill in the imput of the the sign up email. And the rest can be your own message.
And now the new logger should receive an email via the email address he/she entered.
Hopefully this helps.

Can I ask a follow up question -
Is it possible to include something like the User’s Unique ID that’s automatically pulled into the body of the text?
Thanks
Dynamic data can be included into the email body, so you can put user’s id there.
