Drop the action Tag ajouté / supprimé (Tag added / removed) into your workflow and pick the tag to apply (or remove). The action runs against the contact currently flowing through the automation. It is free — no credit is consumed — and it is the most reusable building block in Mailpro, because tags can themselves trigger other automations.
How it works in the builder
Add the add-tag action anywhere in your flow. It takes a single parameter: the tag name. If the tag does not exist yet, Mailpro creates it on the fly. The action runs synchronously — the tag is on the contact before the next step starts — so you can chain "add tag, then send email" knowing the tag is already in place.
The classic chaining pattern
One workflow tags contacts as a side effect of doing its job; another workflow uses that tag as a trigger. Example: workflow A sends a welcome email and ends by adding the tag welcomed. Workflow B is triggered by the tag welcomed and starts a 7-day nurture sequence. To chain several actions inside a single workflow, see chain multiple actions in one automation.
Removing a tag
The same action handles tag removal. Use it to mark "done" states clearly: adds the tag renewed after a successful renewal, then removes the tag renewal-needed. Keeps your tag set clean and makes segment queries reliable.
Treat tags as your workflow currency
Build your tag vocabulary, then chain workflows with it. Refresh on contact tags and how to use tags if needed.
