Suppressions & Deliverability Protection

A Suppression is a protective barrier that permanently blocks outbound emails from being dispatched to specific email addresses.

Emalc maintains an active, workspace-wide suppression engine to ensure compliance with global anti-spam regulations (such as CAN-SPAM and GDPR) and to safeguard your sending domain's sender reputation with major mailbox providers (Gmail, Yahoo, Outlook, and Apple Mail).

How Emails Enter the Suppression List#

Email addresses are added to your suppression registry either automatically through delivery event hooks or manually by workspace administrators:

Automatic Campaign Dispatch Protection#

You never have to worry about accidentally emailing an unsubscribed or bounced contact:

• Pre-Flight Filter: When you schedule or send a broadcast campaign, Emalc automatically cross-checks every recipient against your active suppression table.
• Zero-Credit Deductions: Suppressed contacts are automatically excluded from the final recipient list before credits are calculated or deducted.
• Audit Transparency: You can review excluded contacts in your campaign pre-flight summary before confirming delivery.

Manually Adding a Suppression#

If a subscriber contacts your support desk directly requesting to be removed from all future correspondence, you can manually add them to the suppression list:

1. Navigate to Audience → Suppressions.
2. Click the blue + Add suppression button in the top-right toolbar.
3. In the drawer:
   • Enter the Email Address to suppress (or upload a CSV file with a list of emails).
   • Select the Reason (e.g., Manual, Unsubscribe, or Complaint).
   • Enter an optional description or internal note explaining the reason.
4. Click Save.

Unsuppressing an Email Address#

In rare cases, an active customer may have had a temporary email outage that generated a false-positive bounce, or they may contact you wishing to re-subscribe to your marketing updates.

To Unsuppress an Address:#

1. Go to Audience → Suppressions.
2. Search for the customer's email address in the search bar.
3. In the table row, click the Unsuppress action button (bell icon) or select Remove suppression.
4. Confirm the prompt to remove the address from the blocklist.
