    Postmark imposes rate limits on sending emails, which might be a constraint for businesses with very high or bursty email volumes.
  • Limited Template Customization
    While Postmark allows for the use of email templates, the customization options are more limited compared to specialized email design tools.
  • Geographical Limits
    Postmark's server locations are primarily based in the U.S., which may affect email delivery speeds in other regions.
