Add the Gmail send step
Step 1
Click '+' to add a new step. Search for 'Gmail' and select it. Under 'Choose action event', select 'Send Email'. Click 'Sign in to Gmail' and connect the Google account you want to send from.
Step 2
In the 'To' field, click inside and select 'Email Address' from the trigger output fields (or from the Formatter output if you normalized it). This maps the lead's email as the recipient.
Step 3
In the 'From' field, select your connected Gmail address from the dropdown.
