The suppression list is a per-organization list of email addresses that are blocked from receiving workflow emails. When a Send Email step runs, Formt checks the suppression list first. If the recipient is on the list, the email is skipped automatically.

This protects your sending reputation and ensures you respect recipient preferences. Sending to addresses that have unsubscribed, bounced, or filed spam complaints can damage your domain reputation and cause future emails to land in spam.

Addresses are added to the suppression list in four ways, each tracked with a specific reason:

Use the search bar to find specific addresses, or filter by reason using the dropdown to see only unsubscribes, bounces, or spam reports.

1. Go to Settings → Email.
2. Scroll down to the Suppression List section.
3. You'll see a table of all suppressed addresses with their email, reason, and date added.

Removing an address from the suppression list allows that person to receive workflow emails again.

1. Find the address in the suppression list (use search if needed).
2. Click the menu icon on the right side of the row.
3. Select "Remove" and confirm the action.

If you're migrating from another email platform, you can import your existing suppression list as a CSV file.

1. Go to Settings → Email → Suppression List.
2. Click the "Import" button.
3. Select a CSV or text file containing email addresses (one per line).
4. Formt will import the addresses and skip any that are already suppressed.

You can export your current suppression list as a CSV file for backup or migration purposes.

1. Go to Settings → Email → Suppression List.
2. Click the "Export" button.
3. A CSV file will download with three columns: email, reason, and date_added.

In addition to managing the suppression list from Settings, you can add addresses directly from within a workflow using two step types:

When a Send Email step encounters a suppressed recipient, the step completes successfully but the email is not sent. This is by design — suppression is not an error, it's a safeguard.

• The workflow run continues normally. Suppressed emails don't cause step failures.
• Suppression is checked at send time, not when the workflow is built. If an address is added to the suppression list between when a workflow is created and when it runs, the email will be skipped.

Recipients who unsubscribed can re-subscribe by visiting the same unsubscribe link from their original email and clicking "Re-subscribe." This removes the unsubscribe suppression for that address.

Re-subscribing only removes the "Unsubscribe" reason. If the address was also suppressed for a hard bounce or spam report, those suppressions remain active and the address will still be blocked until those are resolved separately.

• Don't remove spam report suppressions unless the recipient has explicitly asked to receive emails again. Re-sending to someone who reported you as spam will almost certainly result in another complaint.
• Import your suppression list from your previous email platform before sending your first workflow email. This prevents bounces and complaints from addresses that were already problematic.
• Monitor the suppression list regularly. A sudden spike in hard bounces may indicate a problem with your contact list quality. A spike in spam reports may indicate a content or targeting issue.
• Never remove suppressions in bulk to "retry" sending. Each suppression reason exists because something went wrong, and ignoring it will hurt your deliverability.
