Self-hosted alternatives to Spark
Spark is an email app from Readdle that sorts mail with a smart inbox and works with Gmail, Outlook, iCloud, Exchange, Yahoo and IMAP accounts. One listed app does its main job and runs in your own Cloudflare account.
Each answer comes from the app’s README and source code, compared with the features Spark describes on its own site.
