Connect any mailbox to Claude and ChatGPT

Most people do not keep all their email in Gmail. Work mail sits on a custom domain at OVH, IONOS or Gandi, a side project runs on Zoho or Fastmail, and an old Outlook or Hotmail address still receives invoices. These guides show how to connect each of those mailboxes to Claude and ChatGPT through Fezola, one provider at a time: which server and port to use, when you need an app password, and how to check that the connection works before you ask your first question. Once a mailbox is connected, the assistant can search it, read threads and attachments, and prepare reply drafts that stay in your drafts folder until you send them yourself. Start with the custom domain guide if you are not sure who hosts your email.
