How to Include a Video in Your Email Signature
Including a video in your email signature can be an effective way to promote your brand. There are multiple ways of doing this, but I recommend using an image to link to your video. Images attract the eye much better than simple text and will improve click through rates.
Simply embed an attractive thumbnail from your video into your signature, and link it to your video.
Remember: you’ll only want to link to a high quality brand video. If you are emailing a potential client, and they click on your video, you want to make a good first impression. Showing them a low quality video can be a poor reflection of your brand.
