One email is enough

Send us the email address or domain you want suppressed. We add it to a platform-wide suppression list that every campaign checks before sending — so a "no" registered once applies everywhere, for good.

Email [email protected]

Prefer to write it yourself? Email [email protected] with the address or domain to suppress. We confirm within 30 days, usually much sooner.

What happens next

  • We add your address/domain to the platform-wide suppression list.
  • Every current and future Overwise customer is blocked from contacting it.
  • We keep only the suppression entry itself — the minimum needed to honour your objection (Art. 17(3)(b)/(e), Art. 21(3) GDPR).
  • If you were already contacted, the same request also triggers your other rights — access, erasure, correction. Just say so.
