MentionAgent finds relevant blogs and prepares personalized outreach pitches to help customers earn editorial backlinks. It checks prospects for authority and relevance, verifies editor or author email addresses, and holds every draft for customer approval. Customers can edit or discard drafts before sending. The service follows up on email threads, tracks replies, drafts responses, and records placements when links go live. Plans include a separate registered sending domain, a dedicated Gmail inbox, and inbox warmup. Beyond outreach, MentionAgent tracks whether ChatGPT, Gemini, or Claude mentions or cites a customer. Customers can manage drafts and replies in the web dashboard or through Telegram, and an MCP server connects with Claude, Claude Code, Cursor, or another MCP client. It is aimed at founders, small marketing teams, agencies, ecommerce brands, local services, and teams seeking AI search visibility. Starter costs $99 a month; a free trial is available, but there is no free plan. Each warmed inbox is limited to 40 cold emails per day.
