Frequently Asked Questions
Why is AgentMailr free?
We are currently in a Developer Beta phase. Our goal is to empower builders to create the next generation of autonomous AI agents without infrastructure friction. While we will introduce paid plans in the future for massive scale, early adopters will receive generous grandfathered allowances.
How many inboxes can my AI agents create?
Using our API or MCP server, your agents can provision unlimited dynamic inboxes on-the-fly. This is incredibly useful for browser automation agents that need unique email addresses for multiple target platforms.
Do you support Bring Your Own Keys (BYOK)?
Yes. AgentMailr supports Bring Your Own Keys for models like OpenAI, Anthropic, and Google. We encrypt your keys at rest, enabling our extraction endpoints to safely parse verification codes and semantic data from incoming emails.
