Canary vs Unitpost

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.

Unitpost provides transactional and marketing email infrastructure through a visual editor, code or an AI agent. Users can build templates visually or in TSX, personalize them with typed variables and fallbacks, preview them, and send test messages to an inbox. Contacts support custom fields and segments, while opt-outs, bounces and complaints are automatically suppressed. Analytics list delivery rates, opens, clicks and an event timeline. Unitpost offers SDKs for Node.js, Python, Ruby, PHP, Laravel, Go, Rust, Java and.NET, plus a REST API and SMTP relay. Webhooks are HMAC-signed and retried until acknowledged, and inbound email can be parsed into customer workflows. It describes DKIM, SPF and DMARC authentication, suppression, idempotency and rate limits as deliverability measures. Free includes 5,000 emails per month and 200 per day; sending stops at the monthly quota or daily cap. Starter costs $30 a month and Growth costs $200 a month. Enterprise pricing is custom. The site positions its plans for side projects through high-volume or custom-term senders.
