It gives an agent a dedicated email identity for receiving messages, maintaining conversation threads, drafting and sending replies, and handling workflows that otherwise require a human to move information between email and other tools. The inbox can be used for verification codes, registrations, billing messages, support conversations, receipts, and outbound communication. Agents can connect to Mermail through MCP, supported skills, or the CLI. The MCP setup uses an OAuth connection and provides focused mailbox actions such as listing mailboxes, searching emails, loading threads, saving drafts, and sending email. Mermail states that its agent interface includes 72 tools, with each action mapped to a specific mailbox or workflow operation rather than exposing only raw mailbox access. Agent Wallet is an optional layer for tasks that involve payments. Owners can authorize scoped access, set limits and policies, and review activity such as approvals, completed purchases, reports, and receipts. The wallet can support paid research, supported tools, refunds, and online purchases; when a request falls outside the configured policy or needs confirmation, the agent pauses for review. Customer support can be used without connecting a wallet. ## Mermailでできること ### Dedicated agent inboxes Create a mailbox with its own email address so an agent can receive external messages, verification codes, billing mail, support requests, and receipts while keeping conversation history together. ### Focused agent tools Connect through OAuth MCP, skills, or the CLI and use explicit actions such as listing mailboxes, searching email, loading full threads, saving drafts, and sending messages. ### Optional Agent Wallet Add controlled payment access for supported purchases, paid research, refunds, and tools. Wallet grants can be scoped, reduced, or revoked by the workspace owner. ### Policy-based approvals Set spending and workflow boundaries, review outbound drafts or purchases, and require confirmation when a request is unclear or falls outside the configured policy. ### Business context and integrations Bring website or documentation knowledge into support replies and connect services shown by Mermail, including HubSpot, Salesforce, Pipedrive, Shopify, and Wix. ### Workflow templates Start from templates for scheduling, outbound GTM, customer support, or x402 payments, with installation options for official skills or chat-based system prompts. ## 利用シーン ### Customer support inbox An agent can use website and help-center knowledge together with the current conversation to draft or send routine answers, while uncertain questions remain available for human review. Support does not require Agent Wallet. ### Outbound GTM A team can provide campaign rules and a budget for prospect research, have the agent identify prospects and prepare personalized outreach, then review or continue follow-ups until a lead is ready for human involvement. ### Registrations and account verification A dedicated inbox lets an agent receive verification codes and confirmation emails, preserve the surrounding thread, and complete registration-related steps within the agent workflow. ### Paid research and online purchases When a task requires a paid tool or service, the owner can authorize a wallet grant with limits and approvals. The agent can complete an eligible purchase and return the recorded result or receipt. ### Scheduling and coordination The scheduling template lets an agent use its email identity to handle booking-related communication according to the rules provided by the user. ## よくある質問 ### How does an agent connect to Mermail? Mermail supports OAuth MCP, workflow skills, and a CLI. For MCP, the documented flow is to add the Mermail Streamable HTTP endpoint as a custom connector, authorize a workspace, and run a read-only mailbox check. ### Does Mermail let an AI send email automatically? The product supports drafting and sending email from an agent inbox. Users can review outbound drafts, and the site also describes automatic replies or sending for configured workflows; the level of automation depends on the workspace settings and permissions. ### Is Agent Wallet required to use the inbox? No. Mermail describes the wallet as optional, and customer support can operate without it. Wallet access is added separately when an agent needs to make authorized purchases or perform other supported paid actions. ### What happens when a payment request is outside the policy? If a request exceeds the configured policy or its details are unclear, the agent pauses and asks for confirmation before moving funds. Wallet activity records approvals, completed purchases, reports, and receipts. ### What plans are available? Mermail offers Free, Developer, Growth, and Enterprise options. The plans differ in inboxes, email volume, storage, API capacity, team members, support, routing, and enterprise controls; Enterprise limits and deployment requirements are customized. ## クイック情報 - **Category**: AI agent email and workflow automation - **Primary users**: AI agent builders, teams, and workspace owners - **Connection methods**: OAuth MCP, workflow skills, and CLI - **Agent interface**: 72 focused tools, including mailbox and thread actions - **Payment layer**: Optional Agent Wallet with scoped access, approvals, and activity history - **Plans**: Free, Developer, Growth, and custom Enterprise
