To set up Welcome email you need to go through the following steps:
1. Create an email campaign for Welcome emails. Go through the regular Campaigns setups process, with the only 2 differences that you need:
- to choose Triggered campaign type
- to pick email template called "Welcome Email"
2. Change the look and feel of the template the way you want
3. After that go to Schedule and check Distribution Mode. It should be Triggered → Immediately
4. Next, create a mailing list where subscribers will get to from the opt-in forms, that will be used for sending welcome emails. Go to Email → Mailing Lists → Click "Create New Mailing List" → Give it some name
5. Attach this mailing list to the Welcome campaign
6. Then, launch opt-in forms to collect subscribers
7. In opt-in form settings attach the same mailing list and don't forget to attach this opt-in form to your integration code in Setup → Integrations
