Inboxes vs inboxes.net
Two inbox apps with almost the same name solve the same problem: your email API sends mail but gives you nowhere to read and answer it. Here is where they differ, written by the Inboxes team and kept factual.
Summary
Inboxes (inboxes.pro) is a hosted, Gmail-like webmail client that works with Mailgun and Resend. One price, nothing to deploy, and the only inbox app that supports Mailgun.
inboxes.net is an open-source inbox for Resend only. You can self-host it for free or pay $5 a month for their hosted version. It has team roles, shared aliases, history import, and an MCP server so AI agents can read mail.

When to pick Inboxes
- You use Mailgun. Inboxes installs the inbound routes, catch-all, and event webhooks via the Mailgun API. There is no other inbox app for Mailgun. See Mailgun webmail.
- You use both Mailgun and Resend, or plan to switch. Connect both accounts; each mailbox sends through its own provider.
- You do not want to run a server. Hosted only, $5 a month, webhooks and storage handled for you.
- You want a plain, fast personal inbox for hello@ and support@ with threads, search, labels, rules, snooze, scheduled send, and delivery status.
When to pick inboxes.net
- You must self-host. Data stays on your server, no license fee.
- You need a team. Admin and member roles with shared aliases where members only see their assigned addresses.
- You want agents in the loop. Claude Code or any MCP client can read, search, and draft, with sending off by default.
- You want your existing Resend history imported on day one.
What we are adding
Team members with shared mailboxes, history import from Resend, and tracker stripping are on the Inboxes roadmap. We will update this page as they ship. Until then, this table should help you choose honestly rather than by name.

Only Inboxes. inboxes.net is built for Resend. Inboxes connects to Mailgun (routes and webhooks installed via API) and Resend, and you can run both providers in one account.
No. Both use your own API key and your existing domains. For receiving, Resend requires its MX record either way; Mailgun requires Mailgun MX records. The apps never send on your behalf except when you hit Send.
