Who should pick which

  • Social media manager at a small business
    Pick: Buffer's AI Assistant

    Affordable freemium plan, AI-powered content repurposing across 13+ channels, and integrations with Canva and Google Drive streamline social media workflow.

  • Media company managing 10+ newsletters
    Pick: Letterhead

    Letterhead's portfolio analytics, global templates, AI agents for curation, and revenue tools are built specifically for scaling multi-newsletter operations.

  • Solo creator with a single newsletter
    Pick: Buffer's AI Assistant

    Buffer's free tier and simple social scheduling are more appropriate; Letterhead requires custom pricing and is overkill for one newsletter.

  • Enterprise needing dedicated IPs and deliverability tools
    Pick: Letterhead

    Letterhead Suite includes dedicated IPs, automated migration, deliverability reporting, and repair tools for high-volume email sending.
