Envelope FAQs

Question 1

Can I use my existing email accounts with Envelope?

Accepted Answer

Yes, Envelope is designed for 'Bring Your Own' (BYO) mailboxes. It integrates seamlessly with any existing IMAP/SMTP email provider (like Gmail, Fastmail, Migadu, etc.) by simply adding your credentials, with auto-discovery for settings.

Question 2

Are there any per-message sending fees when using Envelope?

Accepted Answer

No, Envelope incurs zero per-message email sending costs. Since it leverages your existing IMAP/SMTP mailbox, you only pay for your standard email provider service, not for each message sent by your AI agents.

Question 3

What is Envelope?

Accepted Answer

Envelope is an open-source API that enables AI agents to send and receive emails directly from your existing IMAP/SMTP mailboxes. It features critical human approval gates for agent-drafted emails and operates with no per-message sending fees.

Question 4

How is Envelope different from other email APIs like Mailgun or Resend?

Accepted Answer

Unlike traditional transactional email services, Envelope works with your existing mailbox (no new domain or DNS setup needed), eliminates per-message fees, offers full IMAP support (read, search, threads), includes vital human approval gates, and is entirely open-source and self-hostable.

Question 5

How does Envelope ensure safe email sending by AI agents?

Accepted Answer

Envelope implements mandatory 'human-in-the-loop' approval gates. AI agents can draft emails, but a human must review and explicitly approve them via a dedicated web UI before they are sent, preventing errors and ensuring human oversight on all communications.
