This method keeps the signature lightweight and ensures the banner loads every time. If the banner size forces you to shrink the logo below 120 pixels in height, the visual impact is lost.
Optimizing Email Banner Size for Maximum Information Density and Impact
For the height, you generally have flexibility, but keeping the file under 200 pixels tall prevents the signature from pushing important content like phone numbers or call-to-action buttons too far down the message. Get them right, and you create a seamless extension of your website and marketing materials.
Using JPEG for complex graphics and PNG for images requiring transparency helps manage weight. A banner that is 600x200 pixels is ideal, but if the file weight exceeds 150KB, some email clients will slow down or block the image entirely.
