Ferry Email
What Ferry Email is
Ferry Email is a free desktop client that places multiple email accounts in one window. It supports Microsoft 365, Outlook.com, Gmail, Google Workspace, iCloud, Fastmail, and standard IMAP, POP3, or SMTP servers. A unified inbox sits alongside a combined, color-tagged calendar with Now, Day, Week, and Month views; another account can be marked busy without exposing event details. The address book merges contact information across accounts, fills itself from mail, and stores data in a file that can live in a synced folder. Tools locate old newsletters, notifications, oversized messages, and unanswered threads before you choose deletions. Ferry can archive a year of mail to a ZIP containing EML files, a JSON index, and README, or save messages as PDFs. Its ferrymail command and Claude skill support searching, reading, drafting, and calendar review, while sending requires explicit approval.
