Once Email
Support Once Email
If Once Email has been useful, you can voluntarily support its maintenance through the verified Ko-fi project page.
Ko-fi project support is open
Support is entirely optional and payment is handled by Ko-fi. Core temporary receiving access does not change based on whether you contribute.

What support would fund
Voluntary contributions help cover domains, servers, mail infrastructure, security maintenance, browser testing, and original privacy education. Core temporary receiving access remains available without payment.
Support is not a purchase
A contribution will not increase mailbox lifetime, speed, quotas, account access, advertising exposure, or editorial influence. It is not a subscription, prepayment, investment, or service-level promise.
Payment and privacy boundary
Payment will take place only on a hosted third-party page. Once Email will not collect card numbers, billing addresses, or payment callbacks. The provider’s own privacy, fee, dispute, and refund rules will apply.
Disputes and refunds
Supporters should use Ko-fi’s process for cancellations, disputes, or refunds. The support button identifies the platform and destination; Ko-fi’s published rules apply on its hosted page.
Recognize the genuine support link
The only valid destination is ko-fi.com/once_email, linked directly from this page. We will never request passwords, verification codes, cryptocurrency, gift cards, or private transfers by email.
