• Excellent deliverability
  Postmark is well-known for its industry-leading email deliverability rates, ensuring that transactional emails reach recipients' inboxes rather than being caught by spam filters.

  Postmark is primarily designed for transactional emails and is not the best fit for large-scale marketing or promotional email campaigns compared to dedicated marketing email platforms.
• Pricing can add up
  While Postmark offers competitive pricing, costs can increase significantly for high-volume senders, and it may become expensive compared to some alternatives at scale.
• Limited marketing automation features
  Unlike all-in-one email platforms, Postmark lacks advanced marketing automation features such as drip campaigns, segmentation tools, and detailed subscriber management.
• Smaller ecosystem compared to competitors
  Compared to larger competitors like SendGrid or Mailgun, Postmark has a smaller ecosystem of third-party integrations, plugins, and community resources.
• No free tier for ongoing use
  Postmark offers a limited trial but does not provide a generous permanent free tier like some competitors, which may be a barrier for small projects or startups with minimal budgets.
