In their own words
GuestPostCRM
GuestPostCRM is an AI-powered platform for managing guest-posting work from opportunity intake through live-link tracking. It sorts incoming client requests into custom email labels and can send automated first replies. AI suggestions use the full email conversation for context, and users can review and edit them before sending. Approved opportunities become deals and orders, with stages, deliverables, and live-link status tracked centrally. The platform generates invoices from approved orders, tracks payments, and can send reminders. Gmail integration is included on the Free plan, while Growth lists Moz integration. API automation is limited on Free and Starter, and is full on Professional and higher tiers. Each automation action consumes GPC credits, with listed costs for actions such as replies, orders, invoices, and email sending. A free one-month trial is advertised. Starter costs $20 a month and includes 12,000 GPC Credits and 3 users. The platform identifies agencies, publishers, SEO teams, resellers, and enterprises as intended users.
MentionAgent
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.
