Spark Mail is an email client (by Readdle) that consolidates multiple accounts (IMAP, Gmail, Outlook, Exchange, Yahoo, iCloud) into one Smart Inbox that filters newsletters and notifications from priority messages. It adds productivity tools like Snooze, Send Later, follow-up reminders, and a Gatekeeper to screen unknown senders, plus AI features for drafting, summarizing, and translating email. Team plans add shared inboxes, email delegation, and private comment threads on messages.
Users connect their existing email accounts, and Spark sorts incoming mail into a Smart Inbox by priority and sender while routing lower-priority mail aside. From there they read, snooze, reply (with optional AI drafting assistance), or delegate/comment on messages with teammates when using a shared inbox.
