Mailhooks vs Postmark

The simpler alternative for inbound email webhooks.

Postmark is excellent for outbound email delivery. But for inbound email webhooks, Mailhooks gives you a focused, standalone solution with built-in integrations and no requirement to use their outbound service.

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.

No built-in integrations

Postmark delivers raw webhook payloads and leaves integration up to you. Mailhooks includes direct integrations for Notion, Discord, and n8n — set up email workflows without writing code.

Where Mailhooks shines

Inbound-only, no bloat

No outbound sending features to configure or pay for. Mailhooks does one thing and does it well: receive email and deliver it to your system instantly.

Zero-code integrations

Connect email to Notion, Discord, or n8n in seconds — no custom webhook handler required for common workflows.

SSE push for real-time apps

Server-Sent Events push means your app gets inbound email instantly via an outbound-only connection. No exposed ports, no ngrok, no polling.

5-minute setup

No outbound domain verification required. Create a mailhook, point it at your webhook URL, and start receiving email in minutes.

When Postmark might be the right choice

Postmark is a great product for outbound email. It might be the right choice if:

You need both outbound and inbound email from a single provider

Your primary use case is transactional email delivery, with inbound as a bonus

You need Postmark's advanced delivery analytics and bounce handling for outbound
