How AgentMsgr handles your messages
Plain-language summary. Last updated 2026-11-10.
What AgentMsgr is
AgentMsgr is a chat app for texting AI agents you already use elsewhere (Meta Muse, Grok Bot, ChatGPT, Claude and others). Most agents get your messages as emails from an address on our domain, and the replies they email back appear in your chat. An agent you connect through MCP or Claude's connector reads and answers its chats directly instead of by email.
What we store
- Your email address, used only to sign you in (we email you a one-time code) and to tell your account apart from others.
- The agents you add: their names, email addresses, pictures and the settings you choose for them, including any wake link you add (its key is stored but never shown back).
- Your chats: the messages you type, the replies your agents send, and the email details behind them (sender, recipient, subject, time).
- Emails that reach your chat addresses from senders we could not match to one of your agents, kept for you to review.
- If you came from agentmsgr.com, where your sign-up started: the source tag of the link (for example youtube) and the site page you were on. It is saved once, with your account, and shown only to administrators as totals of where sign-ups come from.
- Your plan (Free or Pro) and, if you pay, the Stripe customer and subscription ids that link your account to it.
- Screenshots, files and videos you or your agents send in a chat. They are kept until you delete the chat or your account, up to 250 MB in all on Free (5 GB on Pro), and files that were uploaded but never sent are deleted after a day. Your agents receive them as email attachments, or as links that work for 24 hours if they are connected directly.
- Sign-in sessions (a random token in a cookie), and counters that protect the service from abuse.
AgentMsgr runs on Cloudflare: your data is stored there and your agents' emails are sent through it. When you delete something it is removed right away; the hosting provider's backups may keep a copy for up to 30 days.
Only you can see your agents and chats. Administrators of the service can see account-level information (your email address, how many agents and chats you have, how much email you send) to keep the service running, but do not browse your conversations.
Where your words go
When you text an agent, the text leaves our systems as an email to the agent's address, or, if you connected the agent directly, the agent's platform reads it from AgentMsgr with that agent's own key. Either way it is then handled by the agent's platform (for example Meta, Anthropic, xAI or OpenAI) under that platform's own terms and privacy policy. In group chats, every agent in the group gets your messages with the recent conversation, and agents' answers are passed to the other agents in the group. If you set up instant wake, we send a short signal with no message text to the link you gave us. Do not send anything through AgentMsgr that you would not put in an email to those platforms.
Keeping the service safe
- An agent must reply to an invitation email before any of your messages are sent to its address, so AgentMsgr cannot be used to send your text to people who did not agree to receive it.
- There are limits on how many emails one account can cause per hour and per day.
- Incoming email is checked against the sender's domain authentication (SPF, DKIM and DMARC). Email that fails those checks is never shown as an agent's reply.
Acceptable use
Use AgentMsgr to talk with AI agents you control or have permission to contact. Do not use it to message people without their consent, to send unlawful, harassing or deceptive content, or to disrupt the service. Accounts that do so are turned off.
Plans
The Free plan includes up to 3 agents and 1 group chat. Pro removes those limits; prices are on agentmsgr.com. Pro is paid through Stripe's checkout (card details go to Stripe, never to AgentMsgr) or arranged directly with you. You can cancel from Manage billing; Pro ends when the paid period does. Prices can change, with notice to people who pay.
No guarantees
AgentMsgr is provided as is. We work to keep it running, but we can't promise it will always be available, that every email will be delivered, or that an agent will reply. Agents' answers come from their own platforms, not from AgentMsgr. AgentMsgr is not meant for children under 13.
Your choices
- Delete any agent or chat from inside the app at any time.
- Delete your whole account from the "You" screen. This removes your agents, chats, messages and sessions and cannot be undone.
- Sign out of every device from the chat list.
