Swift Mail
Swift Mail (site) is a native macOS client built around the JMAP standard rather than IMAP, with SwiftUI construction, system notifications, keyboard shortcuts, multiple windows, and dark mode. It suits people on Fastmail or other JMAP-friendly providers who want a desktop-first experience. Pricing starts at $2.99/month or $24.99/year ($2.08/month), with a free trial available. The limitation: its JMAP focus means it's less useful if your provider only supports IMAP.
Mimestream
Mimestream (site) is a native macOS email client built specifically for Gmail accounts. It suits Gmail-only users who want a Mac-native feel instead of the browser. There's a 14-day free trial, and paid plans start at $4.99/month or $49.99/year for the Individual plan, with a Group plan at the same pricing. The limitation: it's built for Gmail, so it won't help if you need to manage non-Gmail accounts.
FiloMail for macOS
FiloMail (site) turns your Mac inbox into a to-do list and manages multiple accounts, with AI features like summaries and writing assistance. It suits people who want task-style email handling rather than a traditional folder view. There's a free plan for basic multi-account management, and the Plus plan costs $9.90/month (discounted from $12) for the AI features. The limitation: the AI-driven extras are locked behind the paid tier, so the free plan is fairly basic.
Mailbox for Mac
Mailbox for Mac (site) is a Dropbox-run email tool for clearing inboxes with swipe gestures. It suits existing Dropbox users who want email handled alongside their files. Dropbox's free plan includes 2 GB storage, and paid plans start at $9.99/month for the Plus individual plan (2 TB) or $15/user/month for the Standard team plan, with annual billing available. The limitation: pricing is tied to Dropbox storage plans rather than email features specifically, so you're paying for more than mail.
Polymail
Polymail (site) is an email client aimed at sales and outreach work, with tracking and scheduling features built in. It suits solo operators and founders who send a lot of outbound email. There's a free 7-day trial, then $10/month for the Basic plan, $24/month for Premium, and custom pricing for Enterprise. The limitation: it's priced and built for sales workflows, which is more than a general inbox tool if that's not your use case.
Mailwell
Mailwell (site) is a native Mac mail client supporting IMAP, JMAP, and Microsoft 365 accounts in one place. It suits people who need broad protocol support, including Microsoft 365, which some lighter clients skip. There's a free 14-day trial with no card required; the Founder license is $59 one-time (limited to the first 50 buyers through Dec 31, includes all updates), or a Standard license at $69 one-time with one year of updates, then $29/year. The limitation: it's the most expensive option here and sold as a license rather than a simple monthly subscription.
How to choose
If you want the lowest price and use a JMAP provider, Swift Mail is cheapest. If you're Gmail-only, Mimestream is built for that. If you need Microsoft 365 support alongside IMAP and JMAP, Mailwell covers the most ground but costs the most. For task-style inbox management or sales outreach, FiloMail and Polymail add features bytemail doesn't mention having.
