Is there a free version of Spark Mail?

Yes. Spark's free plan includes unlimited email accounts, Smart Inbox filtering, smart notifications, and core productivity and calendar features — no credit card required.

What do the paid plans add over the free tier?

Paid plans unlock Spark's full AI assistant (drafting, summarization, translation, meeting notes), advanced team collaboration features, custom templates, productivity integrations, and — at higher tiers — HubSpot integration, read statuses, and deeper workflow automation.

Which platforms does Spark Mail support?

Spark is available on iPhone, iPad, Mac, Android, and Windows, plus an Apple Watch companion app, making it one of the few email clients with true cross-platform feature parity.

Can Spark Mail be used for team collaboration?

Yes. Spark supports real-time team collaboration including commenting directly on email threads, shared drafts, and (on higher plans) shared inboxes with unlimited collaborators — all without leaving the email client.

What email providers does Spark work with?

Spark connects to Gmail, Google Workspace, Outlook, Microsoft 365, iCloud, Yahoo, AOL, Hotmail, GMX, and any standard IMAP account, so it works with virtually any email provider.
