Who should pick which

  • Enterprise marketing director

  • Newsletter operations manager at a media company
    Pick: Letterhead

    Manages multiple newsletters; Letterhead's portfolio analytics, lockable templates, and new MCP server for AI agent integrations streamline production and revenue.

    FOMO.ai’s managed service lets agencies scale AI-powered SEO content for clients with brand alignment and E-E-A-T optimization.

  • Solo creator with one newsletter
    Pick: Letterhead

    Not ideal—Letterhead is for teams managing multiple newsletters. Solo creators should look at simpler email tools.
