InboxMail

What it is

InboxMail provides custom-domain email through a centralized private webmail, with aliases for managing multiple addresses. An alias can forward mail to one or more inboxes, keep messages in InboxMail, accept catch-all mail, or block incoming mail. The webmail supports searching, organizing, composing, and replying with a chosen sender identity. Optional AI actions can summarize threads, translate messages, extract tasks, and draft replies. InboxMail offers unlimited aliases and disposable addresses, plus a free useinbox.email subdomain. Developer features include a REST API, retrying webhooks, inboxes for AI agents, a TypeScript SDK, and an MCP server. Delivery events include sent, delivered, opened, clicked, bounced, and complained. 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 plans start with Solo at €5.00 per month, billed €60 yearly, and increase allowances for domains, email, campaigns, AI actions, agent inboxes, and API requests.
