One click, ready for follow-up
- Set an email button to Update contact, then choose the tags, lists, or both that should be applied when a reader clicks.
- Show a branded confirmation with your own message, or continue the reader to a selected page after the update.
- Use the same button in campaign and Flow emails. Incomplete actions are caught before publishing, and repeated clicks do not apply the same action twice.
What to do
Add the button to a draft email, then test the complete path with a test contact. A test email checks the visual design but keeps contact-update buttons inactive, so use a small real campaign or Flow to verify the contact update and any follow-up automation before sending broadly.
