A reply has a home.

Connect incoming email to your own workflow.

Explore the setup
See the workflow, step by step
  1. Separate inboxes by application or workflow.
  2. Receive a message in an active inbox.
  3. Read the thread through the dashboard or API.

Reply headers connect related messages. Keep your application context alongside incoming email without sharing a personal inbox.

Receive email replies in your application

A customer replying to a notification should not disappear into an unmonitored mailbox. InboxIt provides receiving addresses, message retrieval and signed incoming-email webhooks so you can connect that reply to a ticket, order or conversation.

Create a working return address

Create an active inbox. For your own address, verify the domain and receiving MX configuration before assigning it. Set reply_to on outgoing email to that address. Sending-domain verification alone does not configure incoming mail.

Connect events to conversations

Subscribe to email.received. Verify the signature on the raw body, durably accept and deduplicate the event, then fetch the message using its inbox ID and mailbox UID. Preserve UID validity so mailbox resets cannot silently reuse an old identity.

Keep the application in control

Reply headers help match a thread; they do not authenticate a customer. Check account access before acting on a reply. Your app supplies ticket assignment, response policies and durable processing; these are not implied by receiving an email.

Build the first working flow

  1. Configure and test a receiving address with a manual reply.
  2. Register a signed email.received webhook for the workspace.
  3. Fetch incoming messages and associate them with your application records.
  4. Deduplicate retries and monitor failures before enabling automatic actions.

Frequently asked questions

Will verifying my sending domain enable receiving?

No. Configure the receiving domain and MX records and assign an address to an active inbox. Preserve existing employee mail routing; a dedicated receiving subdomain can keep these routes separate.

What can I try for free?

The Free plan includes 1,000 outbound emails and a separate allowance of 1,000 incoming emails per calendar month. Daily sending, storage and retention limits apply. Review the current plan limits before running a large test suite or integration.
