How to Decide
Spark Mail is a smart email client known for its AI‑assisted writing, priority‑based smart inbox and shared team inboxes used by both teams and individual users. The alternatives split into a few clear camps: Shortwave leans on native multi‑platform apps and AI‑native composition/search; Spike emphasizes a chat‑style conversation UI with voice messaging and video calls; Missive focuses on collaborative shared inboxes with email‑to‑task conversion and an open API; Canary Mail distinguishes itself with built‑in PGP encryption and a lifetime purchase option.
When comparing these options, the key factors that actually matter are: the depth of AI assistance (e.g., composition, summarization, search), the collaboration model (shared inboxes, chat‑style threads, task conversion, or team spaces), the platform/deployment approach (native desktop‑mobile apps versus cloud/SaaS), the security offering (encryption or compliance features), and the pricing structure (freemium, subscription per seat, or one‑time lifetime purchase).
