Mailbutler for Gmail

The extension installs in Chrome and works directly inside your Gmail interface, so tracking, merge, signature, and scheduling controls appear alongside your normal compose and reading screens. Many of the core items, such as basic signatures and simple reminders, are approachable on a free plan, while heavy features like open and click tracking, mail merge, and team collaboration are part of the paid Mailbutler suite.

Mailbutler positions itself for anyone who lives in email but needs more structure than Gmail provides natively. Sales teams use open tracking to time follow-ups, marketers push campaigns through signatures and bulk sends, recruiters track candidate engagement, and customer success teams lean on reminders and notes to keep client threads organized. Shared notes, email assignments, and live status indicators make it workable for agencies and larger teams that need visibility into who is handling what.

If you already use Gmail and want tracking, templates, signatures, and light collaboration in one place rather than juggling several tools, Mailbutler bundles them into a single add-on with a straightforward trial path.
