Account & credentials
SMTP and mailbox credentials are stored encrypted at rest where the product requires them. We do not sell your lists or use campaign addresses for third-party advertising.
Security & compliance
Protect the relationship behind every send
How MailShrine protects credentials, campaign data, and sender reputation — encryption practices, DNS auth helpers, and Email Marketing compliance tools.
Campaign & mailbox data
Contacts, sends, and mailbox content stay in your MailShrine account. Access is gated by your login. Team invites for Business Email share only what you authorize.
Sender authentication
Business Email and MailShrine Cloud flows include guidance for SPF, DKIM, and DMARC so receiving providers can verify your domain. Follow the setup helpers when you verify a custom domain.
Email Marketing compliance
Unsubscribe links, one-click opt-out, and suppression lists ship with Email Marketing so you can honor preferences. Always send to people who expect your mail.
Payments
Credit and mailbox checkouts run through established payment providers (for example Stripe and Paystack). MailShrine does not store full card numbers on marketing pages.
