    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.

  • Scope of Services
    Clerky focuses on common legal needs for startups, which may not cover more complex or specialized legal issues requiring personalized legal advice.
