Feature
Opt-outs and bounces, honored automatically in the send path.
Every send passes through a suppression check before dispatch, and every outbound email ships RFC 8058 one-click unsubscribe by default. Opt-outs and bounces are honored automatically — there is no separate suppression list to maintain and remember to apply.
The problem
What makes this hard today.
Manual suppression lists get out of sync
Keeping a separate do-not-mail list updated and applied consistently across campaigns is easy to fall behind on.
Re-mailing a bounced or opted-out address is a real risk
Sending to an address that already bounced or unsubscribed damages both reputation and trust, and in some jurisdictions carries compliance exposure.
One-click unsubscribe is now expected, not optional
Major receivers expect RFC 8058 List-Unsubscribe support from bulk senders; without it, unsubscribe friction itself becomes a complaint driver.
How CogniLead helps
The mechanism, step by step.
Suppression checked before every dispatch
The send path checks the suppression list automatically — there is no separate step to remember or a stale export to re-upload.
RFC 8058 one-click unsubscribe by default
Every outbound email ships one-click unsubscribe support, and the opt-out is honored automatically the moment it is triggered.
Works alongside the reputation circuit-breaker
Suppression keeps individual bad sends from happening; the circuit-breaker (/features/reputation-circuit-breaker) catches aggregate reputation drift — the two guardrails cover different failure modes.
FAQ
Questions about Compliance & suppression.
Can we add addresses or domains to suppression manually?+
Yes — the cognilead.suppress tool/endpoint lets you add an email or domain to the suppression list with a reason; it is then filtered on every future lead automatically.
Is one-click unsubscribe on by default or something we configure?+
On by default — every outbound email ships RFC 8058 one-click unsubscribe without additional setup.
What happens to a hard-bounced address?+
It is suppressed automatically in the send path and will not be re-mailed on a future send or campaign.
