Search and list mailReadAcross one or all your mailboxes, each result naming its account.
Read a message or a threadReadIncluding folders and recent mail.
Read attachmentsReadPDF, Word, text and images; files over 10 MB and images over 3.5 MB are not read, and text is capped at 50,000 characters.

SendWriteOff by default; opt-in per mailbox.

A mailbox is reached through IMAP and SMTP with your address and, when your provider offers one, an app password. Mailboxes that are only reachable from inside your computer, such as Proton Mail through its Bridge, cannot be reached by a hosted connector.

When to choose Fezola

  • Any number of mailboxes: IMAP mailboxes together with Gmail, Outlook.com and iCloud, each result naming its account.
  • The same connection in Claude and ChatGPT: one URL serves both. ChatGPT custom connectors are available on Business, Enterprise and Edu plans.
  • Your own domain: a mailbox on your own domain works wherever its provider offers IMAP: see custom domain email in ChatGPT.
  • One mailbox, one assistant: if your provider publishes its own MCP server, such as Fastmail, you can connect it directly.
  • A shared Memory: your preferences follow you across assistants.

Several accounts

Add any number of IMAP mailboxes beside Gmail, Outlook.com and iCloud. Each is a named source. Example: "Search my OVH and Gmail mailboxes together."

Questions to ask (example prompts)

  • “What needs an answer in my work mailbox?”
  • “Search my OVH and Gmail mailboxes together.”
  • “Find the quote Marc sent last week.”
  • “Summarize the attachment on the last supplier email.”
  • “Draft a reply, from the mailbox that received it.”

A typical use

A freelancer with a mailbox on their own domain and a Gmail asks: "Find the quote Marc sent last week, in either mailbox, and draft a reply." The assistant searches both and drafts the reply in the mailbox that received it. You read it and send it yourself. Example scenario, not a customer story.

Safety

Drafts by default; sending is opt-in per mailbox. An app password, when your provider offers one, is stored encrypted and can be revoked at your provider. What IMAP returns is treated as data, never as instructions. You can disconnect an account in Fezola at any time.
