Inbound Email Parsing: Turn Replies Into Structured Data
Email doesn't have to be a one-way street. Inbound parsing catches messages sent to your app, extracts what matters, and hands it to your code as data — powering reply-by-email, support pipelines, and more.

Most people think of an email platform as something that sends. But receiving is just as powerful, and often overlooked. Inbound parsing lets your application receive email as structured data — turning the inbox into an input for your product, not just an output.
What inbound parsing does
Normally, receiving email means running a mail server, dealing with the raw MIME format, and writing code to pull apart headers, bodies, and attachments. Inbound parsing handles all of that for you. You get an address that accepts mail; when a message arrives, the platform parses it and delivers the pieces — sender, subject, text and HTML bodies, attachments, headers — to your application as a clean, structured payload over a webhook.
Your code never touches raw email. It just receives fields it can act on.
What you can build with it
Once email becomes structured data, a lot of useful patterns open up:
Reply-by-email. Let users respond to a notification and have their reply flow straight into your app — a comment on a ticket, a message in a thread, an answer to a prompt. The user never leaves their inbox.
Support and ticketing. Route support@yourapp.com into your system so every incoming email becomes a ticket automatically, with the sender and body already extracted.
Automated intake. Accept documents, forms, or data sent by email — invoices to process, reports to ingest, submissions to log — without asking anyone to use a portal.
Email-to-action. Trigger workflows from messages: forward something to a dedicated address and have your app do something with it.
How it works in Buzzmark
Every hive comes with its own inbound address — a unique address at the inbound domain. Mail sent to that address is captured, parsed, and made available to your application. Because the address is per-hive, you can dedicate separate inbound streams to separate purposes: one hive's address feeding your support system, another's driving reply-by-email for notifications.
You point your product at the inbound webhook for the hive, and incoming mail starts arriving as structured events you can process like any other input.
A few things to plan for
Incoming email is messy in ways you don't control: people send huge attachments, quote entire threads in their replies, and use every client under the sun. Decide up front how you'll strip quoted history from replies, cap attachment sizes, and handle mail from addresses you don't recognize. And treat inbound content as untrusted input — validate and sanitize it like anything else arriving from the outside world.
Get those basics right and inbound parsing quietly becomes one of the most useful surfaces in your product: the humble email reply, upgraded into a first-class way for users to talk to your software.
