This guide gets you from a Mermail account to a working hosted mailbox.

Prerequisites

  • Access to the Mermail console.
  • A workspace where you can create mailboxes.
  • Harbor storage configured for the workspace if you want to keep full message bodies and attachments.
Hosted mailbox names use the mermail.app domain. Usernames must be 5 to 30 characters and can contain letters, numbers, dots, underscores, and hyphens.

Create your first mailbox

1

Open the console

Go to console.mermail.app and sign in.
2

Choose a workspace

Select the workspace that should own the mailbox. Mailboxes, members, billing, storage settings, and custom domains are scoped to the workspace.
3

Create a hosted mailbox

Click New mailbox, choose a hosted address, and create the mailbox.
4

Send a test email

Send an email from another account to the new address. The message should appear in the mailbox after Cloudflare Email Routing forwards it to Mermail.
5

Ask the mailbox agent

Open the agent panel and ask a question such as:
You have a mailbox when the inbox shows the address, folders, and received messages.

Next steps

Forward existing email

Use Mermail alongside your existing provider and choose which messages the AI can process.

Add a custom domain

Use a verified subdomain when you want mailboxes on your own domain.
