Flowrite: AI Email Writing and Management Assistant
FirstLineGPT was an AI tool for automating cold email personalization at scale. The service is now discontinued and no longer accessible.
FirstLineGPT was a specialized AI-powered tool created to enhance B2B cold email outreach by generating personalized first lines for each prospect. Designed for affordability and efficiency, it allowed businesses to send thousands of custom-tailored emails with minimal manual effort.
The platform focused on solving one of the biggest problems in outbound sales—standing out in crowded inboxes. By using LinkedIn profile data to craft customized first lines, FirstLineGPT significantly improved email open and reply rates.
Users could upload CSV files containing LinkedIn URLs, and FirstLineGPT would automatically extract key details like job title, bio, and achievements to generate relevant first lines.
The platform promised delivery of 3,000 personalized lines in under 3 hours with an 85–90% success rate—ready to use immediately without manual editing.
Unlike competitors that charged premium rates, FirstLineGPT offered high-volume personalization for a flat fee of $49, making it accessible to startups and small sales teams.
As of now, FirstLineGPT is no longer active. Its website is offline, and the tool is not available for current or new users. No official announcement of a replacement or successor has been made.
Sales teams looking for similar personalization capabilities may consider other AI-based cold email platforms that support LinkedIn integration and bulk content generation.
FirstLineGPT demonstrated how AI could transform B2B sales by enabling fast, affordable personalization at scale. It challenged the idea that custom cold emails had to be expensive or time-consuming.
Though discontinued, FirstLineGPT influenced the development of other outbound tools by proving that high-quality personalization could be automated reliably, even across large datasets.
