Flow Designer Email node Documentation

The Email node sends an email to a provided address.

You can send an email to multiple recipients by separating their email addresses by ",", e.g. person1@mail.com,person2@mail.com

If you want to send an email using variables you can use the Text Resolver node to combine the email addresses, e.g. "Tobias Wagner / Email",person2@mail.com,"Marta Schmidt / Email"
