FlyMSG

FlyMSG is a browser-based AI text expander and writing assistant that lets sales professionals, recruiters, and marketers create reusable message shortcuts — called FlyCuts — and generate AI-drafted content directly inside LinkedIn, email, and web apps, eliminating repetitive typing across high-volume outbound workflows.

Developed by Vengreso, a sales productivity and digital selling training company founded in 2017 by CEO Mario Martinez Jr. — a former enterprise sales leader at companies including Cisco and HP who has been named to LinkedIn's Top Sales Voices list multiple times — FlyMSG reflects deep expertise in B2B prospecting and social selling. The tool was built to address the specific pain points of high-volume outbound sellers and recruiters who send hundreds of similar-but-personalized messages per week.

The product works as a Chrome and Microsoft Edge browser extension, available through the Chrome Web Store and Microsoft Edge Add-ons store, making installation lightweight and allowing the tool to follow users wherever they write online without switching contexts. FlyMSG operates across virtually any web-based text field, including Gmail, Outlook on the web, Salesforce, HubSpot, and LinkedIn. Beyond simple snippet expansion, FlyMSG integrates AI-powered content generation that helps users compose LinkedIn posts, comments, prospecting messages, and email replies tailored to their voice and audience.

FlyMSG's core audience is sales professionals, SDRs, account executives, recruiters, customer success managers, and marketers who send high volumes of outbound messages. The tool is particularly oriented around LinkedIn workflows — Vengreso is well known in the social selling space, and FlyMSG includes features tuned for LinkedIn connection requests, InMail responses, post engagement, and prospecting sequences. Vengreso markets FlyMSG as a way to save users approximately one hour per day — roughly 30 hours per month — by automating routine writing tasks. The Chrome Web Store listing has accumulated tens of thousands of users, and the tool maintains a rating above 4.5 stars on G2.

In addition to the writing assistant, Vengreso offers training programs under the FlyMSG brand, including FlyMSG Sales Pro and learning resources around prospecting and LinkedIn selling. This gives the platform a hybrid identity as both a software tool and a sales-skills enablement ecosystem. FlyMSG offers a free tier, individual paid plans starting at $7.95 per month billed annually, team plans with per-seat pricing starting at $14 per seat per month, and custom training bundles for organizations investing in both tooling and skills development. The extension supports pre-built message templates called FlyPlates alongside user-created FlyCuts, with paid tiers offering larger template libraries, expanded AI generation quotas, and team-shared libraries with admin controls.
