Spark Mail

Spark is an intelligent email client that helps you reclaim your inbox by automatically prioritizing important messages. Instead of wading through newsletters and notifications, you see emails from real people first. You can manage multiple accounts from different providers in one unified space, using a Smart Inbox that categorizes incoming mail so you can focus on what matters most.

You can collaborate with your team by drafting emails together in real-time or discussing specific threads in private side-chats. The platform includes a built-in AI assistant to help you draft, rephrase, and proofread replies instantly. Whether you are an individual looking for a cleaner inbox or a team needing better coordination, Spark provides the tools to handle high email volumes without the usual stress.
