Koltrix is a team inbox on your own domain, an email API for your product, and AI agents with inboxes of their own. You choose what each agent may do: draft, ask first, or reply when it is sure. Works with Claude and ChatGPT. 7-day trial, no card.

Real mailboxes on all your domains for $5 a month, flat: up to 50 domains, 100 mailboxes and 25 GB. Ask Claude for hello@yourdomain through the MCP server, or use the CLI or API. Plainmail writes the MX, SPF, DKIM and DMARC records at Cloudflare, Vercel or Porkbun, checks them and creates the mailbox. It's a normal IMAP/SMTP account, so it sits in Apple Mail, the Gmail app, Outlook or Thunderbird. Built for mail between people, not bulk mail.

Real email on the domains you already run on Cloudflare, without paying per seat or forwarding to Gmail. You, your team and your AI agents work from the same inbox, and agents get their own access instead of your password.

Stitch.ai brings mail, calendar, contacts, tasks, notes, sheets, slides, boards, and files into one connected workspace. Stitchy, your AI assistant, works with you across it all. Dual workspace panels allow you to drag, drop, and Stitch anything to everything. Nothing gets lost. AI-powered Knots, Tags, and Connections keep your work organized and easy to surface. Everything is built in: no integrations or extra email clients to set up. Get your work done in one place, without losing context.

Your agents sign up for tools, receive verification codes and reply to customers, mostly from your Gmail or a shared sending pool where one bad actor gets everyone flagged. OpenMail gives every AI agent its own inbox on your domain with its own sending reputation, for one API call each. Incoming mail reaches your code over webhook or WebSocket, attachments arrive as text, and there's a hosted MCP server and a Hermes plugin. Built and hosted in the EU, free for 3 inboxes.

A new mailbox, not a layer over Gmail. Sign-in codes sit on the row with Copy, trackers are removed before you read, scams are called out, and bookings become calendar suggestions. Agents draft under grants you set; nothing leaves without you.

Give your AI agents real inboxes to receive and send emails. Connect them over MCP or API, use your own domain, and get a trust report on every inbound message. Free includes 3,000 messages/month; paid plans start at $9/month.

Agent Inbox gives every AI agent its own email address, Slack handle and Telegram handle, all behind one API. Message your agent from wherever you already work, and it replies in the same thread. It works with Claude, Grok, OpenAI, Hermes and any other agent framework. No more glue code for each channel: your agent gets one inbox, and you get one place to reach it.
