What are Lightweight Images?
Lightweight images refer to compressed or optimized visuals that maintain a balance between quality and file size. In the context of
email marketing, these images load quickly and do not consume excessive bandwidth, providing a seamless experience for the user.
Faster Load Times: Emails with lightweight images load quicker, reducing the likelihood that recipients will abandon the email before viewing it.
Improved Deliverability: Emails with large images may be flagged as spam or not delivered at all. Lightweight images help ensure that your emails reach the inbox.
Better User Experience: Recipients on mobile devices or with slow internet connections will have a smoother experience with lightweight images.
How to Create Lightweight Images
There are several techniques for creating lightweight images: Compression: Use tools like TinyPNG or JPEGmini to reduce file size without significant loss in quality.
Resizing: Scale down images to the exact dimensions needed for the email. No need to include a 4000x3000 image if it will be displayed at 600x400.
File Formats: Choose appropriate formats like JPEG for photographs and PNG for images with transparency. Avoid using BMP or TIFF files.
