Canary vs Postcards

Canary Mail is an email client for managing accounts you already have; it does not provide or host email accounts. It supports Gmail, Outlook, iCloud, Exchange, and IMAP accounts, with apps or access listed for Android, iOS, macOS, Windows, web, and extension platforms. A unified inbox, priority and unread views, selective notifications, snooze, pinning, and cleanup tools help organize messages. Growth and Pro+ include AI Copilot for drafting replies, suggesting subject lines, rewriting in a selected tone, summarizing threads, and searching across accounts. The maker says email is not used to train AI models and that triage and indexing run on the device. Asana and Todoist integrations can turn email into tasks. Pro+ adds PGP and SecureSend encryption, tracker blocking, and phishing detection. Free costs nothing; Growth costs $36 a year; Pro+ costs $100 a year. A seven-day trial needs no card and does not auto-bill; paid subscriptions are yearly, with lifetime purchases also available.

Postcards is a visual drag-and-drop builder for responsive marketing emails made from blocks and templates. Users can export clean HTML or send designs to listed email platforms, including Mailchimp, HubSpot, Klaviyo, SendGrid, Brevo, Constant Contact, and Zoho; export limits depend on the plan. Existing HTML emails can be imported and edited on paid plans. The AI Suite can generate templates from prompts and assist with editing, restyling, restructuring, translation, and design analysis. Shared workspaces, real-time collaboration, comments, and teammate roles support team work. Paid plans include Email Client Preview for checking Gmail, Outlook, Apple Mail, and Yahoo on mobile and desktop. The builder runs in a browser and requires an internet connection, though exported files can be opened and edited offline. Access is through the maker's hosted app link. The free Start plan costs nothing and includes 10 template projects, five monthly exports, 0 AI credits per month, 10 test emails daily, and unlimited teammates. Plus costs $16 a month; Pro costs $24 a month. The maker says user projects and content remain theirs and are not used to train AI models.
