How do I prevent contacts from being added to my automation twice?

If your automation has multiple triggers, it's possible for a contact to enter your automation more than once at different times even though each trigger is set to "Runs Once." To prevent this, you can:

1. Add an “If/Else” statement under your trigger that checks for a tag, (ie, tag is “been in X automation”)
2. If “Yes,” you can end the automation
3. If “No,” add an “add tag” step where you tag contacts with “been in X automation,” followed by the rest of your automation steps
