PigeonPost review
A capable free desktop client for multi-account email, offline search, calendars and contacts.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PigeonPost is a free, open-source desktop email client for Windows, macOS and Linux. It connects to existing IMAP or POP3 accounts, including Gmail, iCloud, Yahoo, Zoho, Fastmail, StartMail, Outlook.com, Hotmail and Microsoft 365. It is aimed at people who want one local application for multiple inboxes, offline reading and search, calendars, contacts and everyday email composition without creating a PigeonPost account or paying a subscription.
The published Free plan costs 0 and includes GPL-3.0 licensing, desktop apps for Windows, macOS and Linux, and no subscription. Its provider coverage is broad for a desktop client: it supports IMAP, POP3, SMTP and CalDAV, with connections for commonly used services such as Gmail, iCloud, Yahoo, Zoho, Fastmail and Microsoft accounts. The optional unified mailbox combines inboxes, while calendar synchronization and .ics import/export help it fit workflows that span more than one provider.
Its feature set is notably wide for a free desktop application. Scheduled sending supports presets or exact times; local search works offline; the calendar offers month, week and day views; and contacts support vCard and CSV import/export. Rich-text composition includes attachments, drafts and signatures, while on-arrival rules handle routine mail organization. Choose PigeonPost if desktop access, local data availability and open-source licensing matter more than mobile apps or AI features. Those seeking a mobile email experience or documented AI capabilities should consider an alternative.
