Suppressions

Suppressions

Suppressions are a list of blocked email addresses that the system will never send to. This protects your domain reputation and ensures compliance with anti-spam regulations. Use suppressions in combination with proper mailbox configuration and campaign settings to maintain a clean sending infrastructure. Pair them with Email Verification for an automated quality filter.

When to review suppressions: Before launching any new campaign (to avoid contacting previously bounced or unsubscribed leads), and weekly during active campaigns to monitor your suppression rate. Also check after importing new lists.

Navigate to app.propersend.pl/suppressions to manage your suppression list.

Block Types

Addresses can be suppressed for several reasons. Understanding the type helps you decide whether and when to re-engage:

| Type | Description | |------|-------------| | Manual | Manually added by you or a team member from CRM | | Unsubscribe | Lead clicked the unsubscribe link in your email (GDPR requirement) | | Bounce | Email address doesn't exist or mail server rejected delivery | | Reply | Lead replied asking to stop contact — check Unibox | | Duplicate | Duplicate address detected across your lead lists | | Invalid email | Failed validation — email format is incorrect or domain doesn't exist | | Spam complaint | Lead marked your message as spam — high-priority flag |

Tip: Suppressions from spam complaints and unsubscribes should almost never be removed. These are strong signals that the recipient does not want your emails. Repeated sends to these addresses can damage your domain reputation.

Scope

Suppressions can be applied at two levels:

| Scope | Description | |-------|-------------| | GLOBAL | Blocks the address across all campaigns and all mailboxes. Use for unsubscribes, spam complaints, and hard bounces. | | CAMPAIGN | Blocks the address only in a specific campaign. Use when a lead asks to stop receiving one campaign but is fine with other outreach. |

Best Practice: Mark unsubscribe and spam complaint suppressions as GLOBAL — these contacts should not receive any future emails from your organization. Mark bounces as CAMPAIGN initially if you want to retry on a different list with better data.

Expiry Policies

Each suppression can have an expiry policy that automatically removes it after a set time:

| Policy | Description | |--------|-------------| | NEVER | Never expires — permanent suppression | | THIRTY_DAYS | Automatically removed after 30 days | | NINETY_DAYS | Automatically removed after 90 days |

Practical example: A soft bounce (temporary delivery failure) might get a 30-day expiry — the address is suppressed now but may work later. A hard bounce (invalid domain) or spam complaint should be set to NEVER expire.

Expired suppressions are automatically removed, so the address can be contacted again in future campaigns if the data quality improves. Use Email Verification to check addresses before removing suppressions.

Best Practices

1. Never remove unsubscribe or spam complaint suppressions — it violates GDPR and damages trust
2. Use CAMPAIGN scope when a lead opts out of one campaign but might be relevant for another
3. Review weekly — catch any incorrectly suppressed addresses
4. Pair with Email Verification — use invalid and disposable results from verification as automatic suppression triggers
