Suppression list: a durable exclusion record for future outreach

Meaning and common confusion

Deleting a contact can remove the very evidence needed to prevent a later import from reintroducing it. Define whether an exclusion applies to one campaign, an address, a domain or a broader system. Zintara's actual owner and exact-domain matching behavior must be checked rather than assumed to be universal.

Worked example

This is a synthetic illustration, not a customer result or a live configuration to copy.

Recipient requests no further outreach
Record preserved in the appropriate exclusion process
Later CSV contains the same address
Expected review: the exclusion still applies; the new row does not erase the request.

Checks to make

1. Verify normalization and exact matching rules.
2. Check overlapping campaigns and imports.
3. Keep the reason and responsible owner available.

Next step and limits

Use suppression and blocklist guides before designing an integration. A campaign pause is not necessarily a durable account-wide exclusion. Preserve the recipient's stated preference while following the organization's applicable data-handling process.
