Courier has introduced Cross-Device Email Preview, a Design Studio add-on that renders email templates on 96 real clients across 21 applications, including Outlook on Windows, Apple Mail, Gmail, and major webmail services, rather than using simulated previews. Users can test unpublished drafts, review screenshots of full inbox views including sender names and subject lines, and assess client-specific behavior such as Outlook’s HTML limitations, Gmail clipping, and varying dark-mode color handling. The feature supports saved workspace-wide target sets, filtering by desktop, mobile, and web clients, as well as a recommended set of eight representative clients; preview runs generally take 10 to 60 seconds and screenshots remain available for one year. Usage is measured per client screenshot, with monthly plans starting at $20 for 100 previews, rising to $50 for 400 and $100 for 1,000.
