Strengths, weaknesses and fit

Strengths

  • Free forever: 4,000 emails per month (Transactional email)
  • Cheaper than most peers for Transactional email ($30.00 vs median $74.85 for 100,000 emails / month)
  • Official MCP server
  • Official agent skills published
  • Restricted API keys with scoped permissions
  • Test mode or test credentials documented
  • Official SDKs in 8 languages

Weaknesses

  • Signed webhooks without replay protection
  • No OAuth 2.0 — API keys only
  • Limited channels: Email only

Not a fit if…

  • you need replay-safe webhook verification out of the box
  • you build a multi-tenant app that acts on customers' own accounts
  • you want several channels from one provider
