Epistles Mail

Epistles Mail is an email client for people who want to manage several mail providers across desktop, mobile and web. It suits readers who value local data storage and offline access more than broad free-account coverage. Its free plan is capped at two accounts; Pro removes that cap and adds secure sending for $35 per year.

Overview

Epistles brings supported accounts into a unified inbox and keeps mail content, attachments, drafts and the search index on the device. That local-first approach, paired with search against a local cache, is a clear fit for privacy-minded users and anyone who needs to work offline. Epistles servers do not store mailbox content; Cloud Vault stores ciphertext only.

Provider coverage includes Gmail, Microsoft 365, Fastmail, JMAP servers, iCloud, Proton and IMAP. The range is useful for people combining personal and work accounts, though the free plan's two-account limit makes it a constrained option for anyone with a larger set of inboxes.

Key features

Local storage and search

Keeping mail data and drafts on-device means the inbox is organized around local access rather than server-side mailbox storage. Search runs against a local cache, supporting offline use. Epistles uses local-first, zero-knowledge encryption, and it passed a CASA Tier 2 security assessment by TAC Security. These measures make privacy a central strength, but users should be comfortable with mail content residing on their device.

Mail, calendar and watch tools

Scheduled sending and calendar tools extend Epistles beyond basic inbox management. iCloud accounts include calendar and contacts support. On Apple Watch and Wear OS, the app supports archive, snooze, pin, template replies and RSVP, giving watch users several ways to triage without opening a phone or desktop app.

Pricing

Free: free, forever, for up to two connected accounts. That is a useful no-cost starting point, but not enough for users who need three or more inboxes.

Pro: $35 per year after a 14-day free trial, with unlimited connected accounts and password-protected, expiring email. One flat price with no per-seat charge suits individuals and teams who need more accounts without a seat-based bill. The trial provides a short window to assess the paid plan before the annual charge begins.

Founding offer: Pay once; available to the first 500 backers. It has no published price, so it cannot be compared with Pro on cost.

Platforms

Epistles is available on macOS, Windows, Linux, iOS, Android and the web, as well as Apple Watch and Wear OS. That broad coverage is useful for people switching among desktop and mobile devices; the watch app also offers concrete triage actions rather than inbox viewing alone.

Who it's for

Epistles is best for privacy-conscious individuals or teams who use several supported providers, need offline access and want their mailbox content kept off Epistles servers. It is less compelling for users who need more than two accounts but will not pay, or who do not want mail stored on their device.

Pros and cons

• Pro: Mail, attachments, drafts and search index remain on-device, with local-cache search and offline access for people who prioritize local control.
• Pro: Broad provider and platform coverage makes it practical for mixed-account setups across desktop, mobile, web and wearables.
• Pro: Pro adds unlimited accounts and password-protected, expiring email for one flat annual price rather than per-seat billing.
• Con: The free plan stops at two connected accounts, so users with larger inbox collections must pay for Pro.
• Con: The $35-per-year Pro price is an ongoing subscription, and the 14-day trial is brief for evaluating a new email workflow.

Alternatives

Choose Spike if its free Starter plan's 3 members, 1 teamspace, 60 days of search history and 15 GB of storage per member better suit a small team than Epistles' two-account cap. Zoho Mail is a better fit for a small group seeking a free plan with five users, one domain and 5 GB of mail storage per user. Spark Mail offers a free plan with unlimited email accounts, Smart Inbox, Smart Notifications, essential productivity features and calendar tools, making it an alternative for users who want unlimited accounts without starting on Epistles Pro.

Newton Mail suits readers who want a free plan capped at two email accounts with monthly read receipts and daily AI actions. eM Client is an option for users who can work within a free limit of two accounts on one device, or prefer its Personal plan at $39.95 per year. Mozilla Thunderbird is the alternative for readers who want free, open-source email with calendar, contacts and multiple-account support.

Canary Mail is another freemium option, with a seven-day trial of its paid features. Saymail offers a free email client with no time limit and support for IMAP, Gmail and Outlook accounts.

Verdict

Choose Epistles Mail if you want offline access, broad provider support and mailbox data kept on your device, and can accept two accounts on the free plan or $35 per year for unlimited accounts. Its strongest case is the combination of local-first storage and cross-platform coverage; its main reason to look elsewhere is the free-tier cap, especially if unlimited accounts at no cost matter more than Epistles' privacy model.
