Yesware

Yesware is a sales engagement and email productivity platform that lives inside Gmail and Outlook, helping sales teams track email opens, link clicks, and attachment views in real time, run multi-touch outreach campaigns and sequences, use shared email templates, schedule meetings, and prospect from a database of 100M+ B2B contacts. It provides bi-directional Salesforce sync to log activities automatically and reporting dashboards on template and team performance. Yesware has been part of Vendasta since October 2022. It does not expose a public developer REST API, GraphQL endpoint, webhook catalog, MCP server or agent card — its own help center answered "does Yesware have a public-facing API" with no, and its entire documentation set at docs.yesware.com is end-user product help. The integration surface is delivered through Salesforce sync, native Gmail/Outlook inbox extensions, LinkedIn, Zoom, Google Meet and Microsoft Teams connectors, and third-party iPaaS platforms. The most machine-readable surface Yesware operates is its Atlassian Statuspage. It was surfaced as a portfolio company of Battery Ventures and GV and profiled in the API Evangelist network.

Yesware is profiled on the APIs.io network. Tagged areas include Company, Sales Engagement, Email Tracking, Sales Productivity, and CRM.

Yesware’s developer surface includes documentation, getting-started guide, support, engineering blog, pricing, signup flow, and 16 more developer resources.

  detail: Yesware ships only an end-user product — every one of the 81 pages in docs.yesware.com's sitemap is Gmail/Outlook
    product help, no API host resolves (api.yesware.com does not exist in DNS), and Yesware's own retired help-center article
    "Does Yesware have a public-facing API instead of a Google extension?" answered no.
