Mailfluid (official product name hellomate) is an AI-driven email outreach and lead generation tool designed to turn simple prompts into high-quality outbound marketing campaigns. Its core capability is to use AI agents to automatically find potential customers, learn brand information, write emails, and handle replies, letting users focus on closing deals.
Purpose Mailfluid is mainly used to automate the cold email outreach process: users only need to describe the type of customer they want to reach, without setting filters or writing Boolean queries, to start lead discovery and email writing. It is suitable for individuals and teams who want to reduce outreach preparation time and increase personalization.
Main capabilities The platform includes three AI agents: Jett is responsible for discovering potential customers, and can search from both LinkedIn profiles and Google Business listings at the same time; Neo is responsible for learning the user's brand information and building a continuously updated knowledge base, so that every email reflects the user's unique value proposition and brand tone; Echo is responsible for writing AI cold emails and intelligent follow-ups, and handling customer replies. In addition, the platform also provides fully managed configuration of a dedicated outreach domain, Google Workspace inbox, and DNS records, so users do not need to handle technical details themselves. All conversations can be viewed centrally in one interface, including sent emails, replies, and follow-ups, without switching between multiple inboxes. Users can review email drafts before sending and can take over any conversation at any time, maintaining control over the process.
How to use Users only need to describe the target customers in natural language, for example by entering the characteristics of the people they want to reach, and Jett will search for potential customers across sources such as LinkedIn and Google Business listings. Neo builds a knowledge base based on the brand materials provided by the user, and Echo generates personalized cold emails and follow-up content based on the knowledge base. Emails are sent through the user's dedicated outreach domain and Google Workspace inbox. Users can review drafts before sending and take over the conversation after a customer replies, turning them into customers. The email examples officially shown include personalized openings aimed at a specific company's recent projects.
Use cases According to the official plan division, Mailfluid is suitable for three types of scenarios: freelancers who want to stop wasting time on client development; small teams that need to run multiple outreach campaigns at the same time; agencies that need to handle high-volume, multi-client outreach work and may need custom assignment, multilingual support, routing, a dedicated customer success manager, and white-label options.
