Posthawk currently supports AWS SES as the email transport. We chose SES for its high deliverability, low cost, and battle-tested infrastructure used by thousands of companies.

Can I use my own domain?

Accepted Answer

Absolutely. Posthawk supports custom sending domains with full SPF, DKIM, and DMARC configuration. You can verify and manage multiple domains through the dashboard.

Posthawk receives incoming emails via SES and forwards them to your application through webhooks. You get the full email body, headers, and attachments parsed and ready to use.

Question 7

Is there a rate limit?

There are no rate limits imposed by Posthawk itself. Your sending rate is determined by your AWS SES account limits, which you can increase by requesting a sending limit increase from AWS.
