Manage email across all your accounts from a single unified inbox
Meridian gives you a single place to read, write, and organize email from every account you use.
Unified Inbox
View emails from all connected accounts — Gmail, Outlook, and Fastmail — in one place. No more switching between apps or browser tabs to stay on top of your messages.
Compose & Reply
Write new messages or respond to existing ones with full compose, reply, reply-all, and forward support. Attach files using the file picker or drag-and-drop directly into your message.
Email Actions
Keep your inbox organized with the actions you expect: star and unstar messages, archive, move to trash, mark as read or unread, snooze for later, and permanently delete.
Conversation Threading
Emails are automatically grouped into conversations so you can follow the full history of a discussion without hunting through your inbox.
Labels & Folders
View and manage your existing organizational structure. Meridian supports Gmail labels and Outlook/Fastmail folders, letting you work with the system each provider uses natively.
Search
Find any message instantly with full-text search across all connected accounts. Search is powered by on-device indexing, so results are fast and your data never leaves your Mac.
Offline Support
Keep working even without an internet connection. Actions you take while offline — sending, archiving, labeling — are queued locally and synced automatically when your connection is restored.
