When choosing the best font for business email signature, pay attention to its size, style, and color.
Fancy, creative signature fonts like at the image below could be bad for your brand’s reputation because they will clutter your email footer or make it hard to read. So it's better to stick to Serif or Sans-serif typeface families.
Serif. Serifs are small lines tailing from the edges of letters. For example, Newoldstamp (in Times New Roman)
Sans-serif fonts, on the contrary, don’t have “serifs” on the end of strokes. For instance, Newoldstamp (in Verdana).
Serifs are generally used to increase contrast and spacing between different letters and improve identification. Sans-serifs are good even in small sizes because of their simple form.
Email signature font size
It is best to use 10-12pt typefaces to ensure easy readability.
Cursive and bold signature fonts
When using italics or bolding, keep in mind that the recipients' eyes will naturally be drawn to the highlighted words. However, it doesn’t mean that you have to make the entire email footer text bold or cursive. To separate your name/title/company name from the rest of the signature, you can put it in bold. See some excellent examples below.
Use your corporate colors to create an aesthetic email signature for your business. However, if you have no company or you don't want to use corporate colors for some reason, here is our advice: combine classic black or grey with any suitable color like blue or green. Try to avoid blood red, light yellow, light green, and other flashy colors which can make your signature hard to read.
