Why teams switch from Postmark to Mailhooks
Inbound is bolted on
Postmark's core business is outbound email delivery. Inbound webhooks are a secondary feature. Mailhooks is purpose-built for inbound email — everything from the dashboard to the API is designed around receiving and routing email.
You need outbound to get inbound
Postmark requires you to set up outbound sending (including domain verification and DNS records) before you can use inbound routes. If you only need to receive email, that's wasted setup time. Mailhooks lets you start receiving in 5 minutes with zero outbound configuration.
