Streak

Streak turns Gmail into your CRM by adding pipelines, deal tracking, and custom views directly in your mailbox. You see all deals and emails in one place, build deal stages that match your process, and track emails without copying information between systems. No separate app to learn or switch to.

Perfect for email-first sales teams who spend most of their day in Gmail anyway. The minimal footprint means adoption is fast and your sales process stays in the tool you already use.
