Tips to Fix Your Mail Signature Blurry, Loading, or Question Marks

1: Give the Right Dimensions for the Image

Dimension is really important to correct the signature layout even in responsive devices like Mac, MacBook, iMac, iPhone, and iPad. Inside the anchor tag use width and height elements with “;” end. also, give the half-size in pixels from the actual size of the picture.

width: 600px;
height: 150px;

2: Use High-Resolution Image

A most common issue is signature images show blurry when we compose a new email on a different device with different screen resolutions. In such a case, a Retina display requires a high-resolution picture for your Photographs or Signature.

If you want to see a Picture width of 600px then your image’s actual width should be 1200px. And if you set height 150px for the actual picture height 300px.

3: Use SVG Image file type

Generally, Decorative graphics, logos, and Pictures in signatures must be in SVG file format. if you don’t have an SVG picture, then you can use an online converter or Default editor to convert your JPG or PNG file into SVG.

Also, SVG takes a small space compared to other image formats. That helps to load your Mail preview fast, even on a slow internet connection. And your receiver gets the image in place of blank spaces or Question Marks.
