Skip Mimestream if
You keep mail on iCloud, Outlook or a work server, because Mimestream won't add those accounts.
Our verdicts
Spark Mail
Free with unlimited email accounts, Spark puts Gmail, Outlook, iCloud and any IMAP inbox together and sorts mail from real people above newsletters and notifications. Gatekeeper makes new senders wait for your approval, and snooze, send later and muting cover the daily cleanup. The AI summaries and meeting notes need Plus at $99 a year, which Setapp subscribers already get, and Gmail-only users get a more native Mac app in Mimestream.
Mimestream
Only Gmail accounts work here, because the app talks to Gmail's own API, so labels, inbox categories, filters and search behave exactly as they do on the web. On top you get a unified inbox for several accounts, aliases, templates, snooze, undo send and blocking of tracking pixels. There is no free plan after the 14-day trial, and Spark's free tier is the better fit if you also need iCloud or Outlook mail.
