What is LobsterMail?
LobsterMail provides simple email infrastructure so AI agents can create and use their own inboxes without human setup. Install the npm SDK and an agent provisions an address in one call — no API keys or credentials required. Built-in protections scan incoming mail to block prompt-injection techniques. Supports custom domains, DNS configuration, webhooks, and dedicated IPs. Offers a free tier and an affordable Builder plan for sending and scaling.
