How recipients join mailing lists
Email addresses are collected when users voluntarily complete and submit forms. Marketing subscriptions are confirmed through a double opt-in process, in which recipients confirm their email address and subscription request through a verification message.
Marketing messages are intended only for recipients with valid consent. Every marketing message should provide an accessible unsubscribe mechanism.
Responsible email practices
StageLetter is intended for legitimate permission-based marketing. Purchased contact lists, unsolicited bulk email, deceptive content and unauthorized use of personal data are prohibited.
