This automation is ideal when you want to categorize or label incoming messages such as tagging leads, support requests, or internal updates, based on specific conditions like email subject or sender.
Step 1: Go to Workflow Setup #
- Click on Workflow from the sidebar.
- Click + Create Workflow in the top-right corner.

Step 2: Select Trigger Type #
- Enter a Workflow Name such as
Tag Contact Form Messages. - Under the Inbox tab, choose New Message Received as the trigger.
Step 3: Define the Condition #
- Under the IF section, choose:
- Subject as the condition
- Contain as the match rule
- Enter the keyword or phrase (e.g.,

This means: if the subject of an incoming email contains [Contact Form], the workflow will run.

- Under the THEN section, choose Assign Tag.
- In the tag selection dropdown, choose from existing tags like:
