When Mailgun wins

  • Developers integrating receipts, notifications, and password-reset emails
  • Teams already on a marketing ESP that need a separate transactional channel
  • High-volume B2B applications with strict deliverability requirements

Where Mailgun is the wrong fit

  • Marketing teams seeking campaign tooling (use Mailchimp or Kit)
  • Creators sending newsletters (use Kit or beehiiv)
  • Free-tier hobbyists with low total volume but spiky daily-cap-bumping use cases

When Postscript wins

  • Shopify e-commerce stores doing $1M+ GMV with active SMS list growth
  • Brands graduating from Klaviyo SMS or Attentive on cost
  • Teams wanting a Shopify-native SMS experience separate from email

Where Postscript is the wrong fit

  • B2B companies, where SMS is not a standard channel
  • Creators or info-product sellers whose per-message economics do not match
  • Brands without an SMS-friendly Shopify segment to drive ROI
