Double opt-in
A submitted address is not treated as subscribed until the owner confirms the link sent to their inbox.

Consent-first audience building
Build an audience you can contact directly, with double opt-in and the evidence needed to show when and how each subscriber confirmed.
Discuss this serviceThe promise
A submitted address is not treated as subscribed until the owner confirms the link sent to their inbox.
Confirmation timestamps and request context are retained to support a defensible consent record.
Unsubscribe handling is part of the same controlled audience record, not a disconnected spreadsheet.
Current availability
Audience capture and confirmation are available. Marketing campaign sends remain disabled until compliant sender details, including a valid postal address, are configured.
How it works
Offer a clear reason to subscribe wherever your audience already encounters the brand.
Send a confirmation link and activate the record only after the recipient chooses to join.
Retain the source, timestamps and relevant request context behind that consent.
Operate campaigns only after sender identity, postal address and delivery configuration are complete.
