The ideal size of GIF should be upto 1mb. GIF is kind of Image format. There is a limit for Image file size in the email, but no specific limit for GIF. A good practice is to keep it upto 250 pixels. Many ESP’s consider Gif under 250 pixels. As decreasing file size leads to increased loading speed. Email with a lot of content may take a lot of time in loading all its contents which may make you lose your leads due to their loss of interest.
GIF can be optimized using 4 simple tactics:
Cropping: Focus on the part that’s animated and crop the rest.
Remove framing: Keep it simple and focused, just like the totality of your email.
Animate only part of the picture that you need: Use the layers in Photoshop that will allow you to isolate animated parts only.
Reduce colors: The reduction is color use can decrease the file size.
A responsive design is faster to load and pleasant to the eye of the viewer.
For the responsive design with images, a change in CSS should be done:
In CSS, img { max-width: 100%; } used instead use width: 100% because every image will load in its original size, unless the viewing area becomes narrower than the image’s original width.
While the above is a great quick fix and a good start to responsive images and file size.
