Can I use a custom subject per flow?

Send email via flow

The email step picks the template and recipient column from the trigger data table. With Mail Approval enabled, emails may queue for approval first.

Choose a template from workspace Email Templates.

Select the column that holds the recipient email; it must exist on the trigger table.

With Mail Approval on, emails go to the approval queue instead of sending immediately (within limits).

1. Open the flow and go to the email step (after trigger and form).

2. Select a template; create one under Email Templates if needed (see Create templates).

3. Choose the recipient column (e.g. "Email"). Save.

4. Map template variables to data table columns if needed.

5. Save the flow. With Mail Approval, approve queued emails or enable auto-send (see Set up Mail Approval).

Test the template in the editor; ensure the form link placeholder is correct.

Check Understand limits for enough sending capacity for flow volume.

Email not delivered: check recipient column, spam, and Mail Approval queue. See Flow debugging.

Template missing: create one under Email Templates and link it in the flow.

The subject is usually in the template. Pick a different template per flow for different subjects.
