Visual communication has never been more important for businesses. Images not only complement the text, but also evoke emotion. To design appealing and high-performance emailing campaigns, it is very important for marketers to integrate images in their messages.

The imagery of your emails must also be in line with your brand image, voice and values. To illustrate your messages, you can use your own photos, hire a professional, or utilize stock images. Depending on your brand personality, animated images like GIFs can also be an option.
There are different things that you need to take into account about images when designing an email campaign:
If you don’t have photos of your own and that you are looking for images for your emails, check websites like Unsplash and Pixabay. These are online image banks that offer nice photos for free. If you’re opting for animated images, GIPHY is the top source for GIFs and stickers.
