The Developer’s Guide to Killing Your Mail Server

The Pain of DIY Inbound Email

Let’s break it down:

• MX Records: You’re configuring DNS for every domain.

• Parsing: You’re decoding multipart MIME by hand (and testing every weird edge case).

• Spam Filtering: You either accept everything (hello, spam) or write clunky filters.

• Retries & Queues: A single transient bounce? Your email is gone forever.

• Monitoring: If your server goes down, so do your customer workflows.

All of this just to get what you actually need — subject, sender, body text, and attachments — into your app.

The API Era of Email

Thankfully, the tide is turning. With players like Resend announcing a private beta for inbound email, and tools like inbound.new already in production, email receiving is finally getting the same treatment as email sending:

• Webhook-first: Your app just receives structured JSON.

• Simple domain setup: One-click MX + DKIM config.

• Attachments + metadata: No more parsing nightmares.

• Retries + deduplication: Because dropped messages aren’t an option.
