Inbox-Accurate Previews
Catch rendering issues before subscribers do.
See how your email renders in real clients and devices, not just simulated previews. Compare layouts and spot visual issues across desktop and mobile before launch.
Every device. Both modes.
Preview your email in light and dark mode across the apps and devices your subscribers actually use.
Compare renders quickly, spot layout issues early, and review screenshots before launch.
Real apps, real hardware
Preflight captures screenshots from real email apps running on managed hardware, so what you review is aligned with how subscribers actually see your campaign.

Forced dark mode
Preview forced dark mode rendering in Chrome to catch algorithmic color inversions and contrast regressions before launch.
These inversions are common in many Android email clients, including Gmail, Samsung Mail, Yahoo, K-9, and GMX.
Use this alongside light and dark mode captures to validate text readability, brand colors, and CTA visibility.
