Optimize images for email — right inside Mailpro™.
Crop, resize, compress and add ALT text without ever leaving your campaign. Prepare visuals that load fast and render everywhere — no switching tools, no re-uploads.
Why optimize images for email?
The Mailpro image editor streamlines everything you need to prepare visuals: crop and resize to the right dimensions, compress to reduce file size, and add accessible ALT text — all inside the editor. Lighter images load faster and improve engagement, uniform sizes keep your branding consistent, and descriptive ALT text keeps content understandable with images off or on a screen reader.
