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

- 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
