An everyday inbox
Conversation threads, inline replies, contacts, signatures, search and bulk actions.
Explore the inbox →Room to write
Formatted composing, focus mode, drafts with attachments, Undo Send and Send Later.
Read the mail guide →Your own domain
Guided DNS checks, aliases, separate human or agent mailboxes and per-domain signing.
Connect a domain →Mail for agents
Mailbox registration, REST and MCP, attachments, signed webhooks, scoped access keys with budgets, and key rotation.
Explore the API →Delivery you can follow
Recipient delivery status, bounce handling and invalid-address suppressions.
Understand delivery →Privacy and account security
Two-factor authentication, verified recovery and optional OpenPGP message-body encryption. Reading encrypted mail still needs an external client.

Planned work, in priority order. These are the next improvements, not features you can enable yet. Timing may change as we test them.
Give each integration the access it needs.
Scoped read/send keys, address restrictions and recipient budgets are available. Draft-only keys and a human approval inbox are also available. Next: consistent reply, attachment and mailbox synchronization workflows across REST and MCP, with tested integrations.
Make encrypted conversations easier.
Reliable key import and backup, readable fingerprints and key-change notices. Then decryption, signing and signature verification for people and agents, followed by encrypted attachments. Clear key ownership stays central throughout. Hardware-backed sign-in and hardware-held PGP keys are longer-term directions, after dependable recovery and interoperability.
Improving along the way
Build confidence in every send.
Broader delivery tests across providers, complaint handling and measured transactional sending from real applications. Submission and delivery tracking are available; acceptance by our server does not guarantee arrival in a recipient’s inbox. Higher-volume sending has separate pricing and review.
Make it easier to bring your world with you.
Multiple paid domains, a Neo migration guide and a read-only folder preview are available. Next owner pilot: resumable copying of mailbox history, then move daily mail over in stages. Then performance for larger mailboxes and more ways to organize messages. Connect KeyKeeper to the wider Key* services with explicit identity, permissions and credit boundaries.
