To add a banner, host the image publicly, place it below your details, and link it to the page you are promoting. To add a disclaimer, put a short line of small grey text at the very bottom. The key with both is restraint: they support the signature rather than take it over. Here is how to do each well.
Adding a banner
A banner is useful for a current campaign, an event, or a single call to action. To keep it effective:
- Design the banner and host the image at a public web address so it loads for recipients.
- Place it below your name and contact details, not above them.
- Wrap it in a link to the relevant page so a click goes somewhere useful.
- Keep it within the signature width, around 600 pixels, and keep the file small so it loads fast.
One banner is enough. Several stacked images turn the signature into an advert and bury your actual details. Sizing guidance is in the signature size and dimensions guide.
Adding a disclaimer
A disclaimer should be present without being loud:
- Keep it short. A line or two is usually all that is needed.
- Set it in small, grey text so it sits quietly under everything else.
- Put it at the very bottom, below contact details and any banner.
Long blocks of legal text make every email look heavy and get skipped anyway. If your company mandates specific wording, use exactly that, kept small.
Don’t crowd the essentials
Your name, role and the quickest way to reach you should still be the clearest part of the signature. A banner and a disclaimer are extras that frame those essentials, not replacements for them. The principles are in what makes a good email signature.
Test on a phone
Banners and disclaimers add height, which shows up most on small screens. Send a test to yourself and open it on a phone to be sure the signature still reads cleanly and the banner is not cut off.
