We have created a welcome mail, but mail is not being sent. We added the tag also. But unable to send please help us in sending the welcome to new patients.
I apologize that you are expereincing this. Are the contacts that are being added to the list being added manually or via a sign-up form?
Our Welcome Email is for use of new sign-ups via a sign-up form. If you are wanting it to be sent to contacts you are adding manually, you would want to use an Email Automation.
