How Do Email Signature Banners Work?
An email signature banner works by enticing your recipients to click on the link in your banner. That is why you have to make a really attractive banner that defines a problem and provides a call-to-action (CTA).
Implementing a thoughtful banner in your company-wide email signature that points to your website, will likely see an increase in traffic to your website. Furthermore, that should hopefully convert to more listings.
Once everything looks right, go ahead and install your email signature into your email client and test it out.
