    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.

    Postmark's server locations are primarily based in the U.S., which may affect email delivery speeds in other regions.

    Postmark does not offer SMS sending capabilities, which may be a drawback for businesses looking to consolidate their communication channels.
