Best size for email signature logo

The ideal size for an email signature logo depends on several factors, including the resolution of the logo, the font size and style of the text, and the overall design of the signature. However, here are some general guidelines for email signature logo sizes:

1. Maximum width: 640 pixels (px) or 80-100 characters (including spaces) to ensure that the logo doesn't get cut off in most email clients.
2. Height: 100-150 pixels (px) to maintain a good balance between the logo and the text.
3. File size: Keep the file size under 50 KB to ensure quick loading times and to avoid overwhelming email clients.
4. Resolution: Use a high-resolution logo (at least 72 dpi) to ensure that it looks crisp and clear in most email clients.
