Scoped agent access

Give each agent a specific set of inboxes and actions. Retrieving the inboxes a task needs can reduce irrelevant text passed to an agent. Token use depends on the agent and retrieval strategy.

One central inbox, many otter subs

Replace 10+ separate accounts with purpose inboxes. All Mail is a human view that can include every active compartment while Personal stays focused on the main address.

Personal

Keep mailing-list mail out of Personal by using its own address. One itinerary appears once in All Mail with Flights and Hotels origins.

Better email view

Follow the conversation, including who joined. The preview keeps visible headers, recipient changes, and branches legible without inferring hidden context.

Create. Connect. Archive.

Create a purpose inbox, connect an agent with fine-grained controls, then retire the whole inbox while retained mail remains available.

Create an inbox

Choose a purpose address. The prototype does not send a test email.

Archive does not unsubscribe from an external mailing-list provider.

One policy layer. REST and MCP are two doors.

Agents bring their own model. OtterMail provides scoped inbox operations and the approval path beneath either interface.

MCP v2 preview: list scoped inboxes, search, read a message, create a draft, request approval.

Demo data. One authenticated operation counts once across REST and MCP. This landing preview does not connect to a provider.

Capacity for the way you work.

Four paid tiers use the same scope, revocation, audit, and approval vocabulary. Choose room for organized mail and agent operations.

Practical questions, answered plainly.

Scope, sending, archiving, domains, and the product boundary in the language the controls use.

An agent receives the inboxes named in its grant, with the actions you select: read, search, organize, or draft. Send permission is separate, and the demonstrated send path stays behind human approval.

OtterMail

Give your agent one inbox to start.
