InboxMail provides custom-domain email through a private webmail interface, with aliases for handling many addresses. Each alias can forward messages to one or more inboxes, keep mail in InboxMail, accept catch-all mail, or block it. The webmail supports searching, organizing, composing, and replying with a selected sender identity. On-demand AI actions can summarize threads, translate messages, extract tasks, and draft replies. Users can create unlimited aliases and disposable addresses, and claim a free useinbox.email subdomain. Developer tools include a REST API, retrying webhooks, agent inboxes, a TypeScript SDK, and an MCP server; delivery events cover sent, delivered, opened, clicked, bounced, and complained messages. The site says stored content is encrypted with AES-256-GCM, with keys protected by the account password and a 12-word recovery phrase. A free plan includes one custom domain and 50 emails per day. Paid monthly plans start at 5.00 EUR per month for Solo, billed €60 yearly, and scale up in domains, messages, campaigns, AI actions, agent inboxes, and API allowances.
