PSMJ Resources, Inc. – by David Whitemyer, AIA – Most professionals receive between 50 and 100 emails each day. In addition to making your subject line clear and your email body brief and to-the-point, your signature should look mature and not distracting. Here are a few tips on fixing your email signature. 
Get Rid of the Image – Are you using a JPG or TIFF or some other type of image file in your signature, perhaps as your logo? Delete it and create a new signature with common font text. A number of email providers are set up to block images within emails. If you must include your logo, review your email settings and instructions on how to create an image within a signature, which may include also using “Alternative Text.”
Clean it Up – Your email signature should include your name, title, company, and primary contact info – which is probably your cell or desk phone number. It doesn’t need your street address, full web address, blog sites, or social media buttons. If anyone needs these, Google is just a click away. And for Pete’s sake, get rid of your fax number, advertisements, and any inspirational quotes.
Make it Work Everywhere – These days, professionals are using their smartphones and tablets to check email and surf the web more than on their computers. Make sure your signature isn’t so tiny that people can’t read it on an iPhone or Droid. San serif fonts are best for small screens. If your signature includes any links, test them on different devices, to make sure they work on phones, on PCs, on Macs, and on an iPad.
