For sending receipts and verification emails, a good default choice is:

Best overall: Postmark

  • Excellent deliverability for transactional emails
  • Very reliable for receipts, password resets, and verification flows
  • Simple API and good templates
  • Strong reputation with mailbox providers

Also good options

  • SendGrid — flexible and widely used, good if you want more features and scale
  • Amazon SES — very low cost, but more setup and less polished
  • Mailgun — solid API and tooling, good transactional support

If you want the simplest recommendation

  • Postmark if you care most about deliverability and ease of use
  • Amazon SES if cost is the biggest concern

If you want, I can also recommend the best provider based on your budget, expected email volume, and whether you need marketing emails too.
