Deep Dive: Switching from Airmail to Spark Free
Trade-offs, installation & data architecture
What you trade away
Spark Free is polished but offers less granular action and automation customization than Airmail and requires a Spark account for synchronization.
How to deploy Spark Free
Install Spark on macOS, Windows, iOS, or Android, create a Spark account, and connect existing mailboxes
What it takes to run
Requires a Spark account and mailbox OAuth or credentials, but no server administration
Where your data lives
Mail remains at the provider and is indexed locally; encrypted synchronization and notification metadata, and temporarily queued send-later messages, can live on Spark's servers; AI excerpts may be sent to a disclosed provider when AI is used
Why fork Spark Free instead of vibe-coding a Airmail clone?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Airmail, create a configurable Apple email client with actions, snooze, and send later. The hard boundary is native apps, provider quirks, automation, push, and years of compatibility work, plus mail infrastructure, integrations, and client polish.
