Mailfence

Mailfence is a private email and collaboration suite run by ContactOffice Group, a Belgian company selling hosted email and groupware since 1999. A Mailfence account bundles encrypted email with integrated OpenPGP key management (generate, import, export, revoke keys inside the web UI), shared calendars, a contacts manager, cloud documents, groups for team collaboration, and chat. Because the servers sit in Belgium, user data falls under EU and Belgian privacy law rather than US jurisdiction, and Mailfence publishes an annual transparency report on law-enforcement requests. Paid plans offer IMAP and SMTP access, custom-domain email, aliases, and more storage; a free tier with limits is available for users who want to evaluate the product.

Mailfence's audience skews toward privacy-focused individuals, activists, journalists, and small teams that want integrated calendar and document collaboration rather than just a mailbox. It also picks up customers who liked the Proton Mail concept but want an alternate jurisdiction or a provider with built-in PGP key handling they control rather than proprietary encryption stacks. Affiliate reviewers typically compare it against Proton Mail, Tuta, StartMail, and Posteo on jurisdiction, encryption model, and groupware breadth. Pricing starts around EUR 3.50 per month for the Entry plan and scales to Pro and Ultra tiers with more storage, aliases, and custom-domain support.

Mailfence runs its affiliate program directly via ContactOffice Group rather than a public network. Prospective partners email affiliate@mailfence.com with a link to their site, their audience profile, and the privacy or security topics they cover; Mailfence evaluates each application by hand and onboards partners it considers a good editorial fit. Approved partners get a tracking link, banners on request, and a dashboard to monitor referred signups.

Commissions pay out whenever a referred viewer subscribes to a Mailfence paid plan. The attribution persists even if the user first signs up on the free plan and later upgrades, so free-to-paid conversions still credit the original affiliate, which Mailfence frames as lifetime user attribution rather than a fixed cookie window. The exact headline commission rate is not published on the affiliate page and is set per partner during onboarding; third-party listings describe it as a revenue-share on the referred user's paid subscription. Payouts run monthly via bank transfer or PayPal; Mailfence does not publish a minimum threshold publicly, and exact terms are confirmed in the partner agreement. Incentivized traffic, bulk mailing of links, and branded-keyword PPC are not permitted.
