Direct answer
What is Spark Mail?
Spark Mail is an inbox management and email client designed to reduce distractions. It offers smart triage, sender grouping, team collaboration, and Azure OpenAI-powered drafting and summarization.
Spark Mail is a cross-platform email client engineered to filter noise and help users focus on high-priority correspondence. Operating across macOS, iOS, Windows, Android, and Apple Watch, it aggregates accounts from Google, Microsoft Exchange, Outlook, Yahoo, iCloud, and standard IMAP into a unified inbox. The application structures daily email handling around deep work habits. The Smart Inbox automatically separates priority personal messages from automated newsletters and notifications. A built-in Gatekeeper lets recipients screen and block new senders before their messages reach the main inbox, while features like Set Aside, Done Marker, Snooze, and Pin help organize tasks without leaving the client. Spark +AI adds generative writing and text processing powered by Azure OpenAI Service. Users can draft new messages from conversational prompts, trigger quick one-click replies, adjust tone between formal and friendly, proofread, rephrase, expand, or shorten drafts. For incoming mail, Spark +AI provides short, detailed, or action-point summaries of long threads and translates incoming and outgoing messages directly in-app. In addition, Spark includes +AI Meeting Notes to transcribe and summarize virtual calls across platforms. For collaborative workflows, Spark enables team-based email operations. Teammates can co-draft emails in real time, share specific threads, chat through internal private comments with attachments, delegate email ownership, and run shared inboxes.
Spark pairs full cross-platform inbox triage—including Gatekeeper screening and automated sender bundling—with native team co-drafting and Azure OpenAI-powered writing, translation, and meeting transcription.
