Shortwave review

Shortwave is an email client that puts an AI assistant at the center. Business, at $30 per seat a month, includes Standard intelligence on Claude Sonnet 4.6, roughly 150 to 300 Standard AI requests a day, AI search over five years of history, three AI-powered filters, attachment analysis, AI memory, saved prompts, instant AI replies and personalized writing that learns your style and tone from the emails you send. Premier, at $45, moves to Advanced intelligence with adaptive thinking, doubles usage and removes the search history limit, and Max, at $120, uses Claude Opus 4.6 with six times the usage. Read statuses, link tracking, snippets, splits and bundles round out the inbox tools. A sister product, Tasklet, can draft replies around the clock and connect to 3,000+ apps. The catch is cost: there is no free plan on the pricing page, so Shortwave is the priciest everyday option here after Fyxer and Jasper.
