Mailfence Ultra, € 29.00/mo. on Linux Emails

Ultra is presented as the top subscription tier priced at 29 EUR per month, with billing described as monthly for the plan. It is positioned as the maximum-capacity option for organizations and power users who want the largest quotas, broadest feature coverage, and premium support.
The plan includes 225 GB total storage, broken down as 60 GB for emails and 165 GB for documents, supporting high-volume mailboxes, long retention needs, and document-heavy workflows.
It includes 200 aliases, enabling large-scale address organization across departments, projects, and roles, while maintaining centralized management under one subscription.
Encryption is included to support secure communications, and the tier is shown with advanced access options such as standard mail client protocols (POP, IMAP, SMTP) and mobile synchronization (ActiveSync) to support enterprise-style usage across many devices.
This tier is also shown as including user management and custom domain email capability with DKIM, SPF, and DMARC controls, supporting stronger deliverability and domain-based identity management.
Support is positioned as priority support via email plus telephone for faster assistance. The tier is also associated with a commitment to donate a portion of Ultra revenues to privacy-focused organizations, aligning the premium tier with broader privacy advocacy.

Mailfence is positioned as a secure and private email service delivered as an integrated suite that combines messages, calendars, documents, and group collaboration in one account.
Privacy positioning emphasizes no advertising, no trackers, and no data mining, with operations under Belgian jurisdiction and EU privacy protections.
Security features highlighted across the service include browser-based end-to-end encryption using OpenPGP, digital signatures for sender verification, and an integrated keystore for creating, importing, publishing, and managing keys.
Access methods referenced include web access plus secure protocols (POPS, IMAPS, SMTPS) for paid plans, and mobile support through iOS/Android and progressive web app style access.
Higher tiers add capabilities such as aliases, user management, and custom domain email with deliverability and authentication controls like DKIM, SPF, and DMARC.
Operational notes emphasize that attachments are handled with virus-checking routines and that subscriptions can be upgraded via account settings.
Payments supported for subscriptions include credit cards (Visa and Eurocard/Mastercard), PayPal, cryptocurrency payments (treated as Bitcoin for reporting), and wire transfer by contacting support, while subscriptions are described as non-refundable because the free tier can be used to test the service.
The service is presented as operating on 100% green energy and as subscription-funded rather than ad-funded.
