Measures earned, engagement-weighted share of voice across the GTM voices panel. Methodology →
Mailreach positions itself as a narrow, single-purpose alternative to consolidated outbound platforms: a warmup and deliverability layer built for teams that already run a sending stack and want inbox placement handled separately, arguing that broader tools let deliverability get sidelined. It targets sales teams, recruiters, and lead-generation shops running cold outreach at volume, buyers who care more about landing in the inbox than about campaign design. In the conversation the Index tracks, that footprint reads early rather than established, a name attached to the deliverability corner of the outbound stack rather than a subject of active comparison or debate.

Business Profile
Mailreach launched in 2020 out of Paris, founded by Florian Boulay and Damien Brenelière, and has grown as a bootstrapped company rather than a venture-funded one. It runs today with a team of three, a scale consistent with its positioning as a narrow, single-purpose tool rather than a platform trying to cover the full outbound stack. Its customer roster includes DocuSign, Calendly, Asana, Eventbrite, Aircall, and Gorgias, sizable SaaS companies that use it as a deliverability layer alongside their existing sending tools rather than as the core of their outbound program.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Mailreach exposes a public API with webhooks and client libraries across Shell, Ruby, Node.js, PHP, and Python. Its documentation references Model Context Protocol as an integration path, and the product includes an in-app AI assistant, Mailreach Co-pilot, that surfaces actionable insights on email content and sending behavior. The API and webhook layer is the agent-facing surface today, with MCP referenced as the next step.
