Most, if not all of the marketing emails you send out likely include images to illustrate the content. But are you using best practices to get the most from your images?
It takes more than just pretty pictures to be successful. So what do you need to know about images?
The 80/20 Rule - As a general rule of thumb, you should try to balance your email with no more than 20% image content and 80% text content. Though 25 / 75 and 30 / 70 are not bad ratios either. How do you calculate this ratio?
Just look over your email. If it looks like it is roughly 20% image content to 80% text content then you’re doing just fine. This particular rule is more of a guide than an exact science.
Why should you follow this rule? Because many email browsers these days - around 40% or so - initially block images when the email arrives in the inbox, requiring the recipient to click a button or a link to turn the images on. If your email is too image heavy then your recipients may not see enough content to take action, leaving them with no reason to turn your images on and see the full impact of your message.
Use the Quick Preview tool in the Canvas, Salesforce Mail Template and Freeform editors to take a look at how your email looks with images turned off.
Use Alt-Text - Giving all your images alternative text essentially provides you with an “emergency backup” in case a recipient cannot initially see your images. Many of the same email browsers that block images will display the alt-text for the image so that the recipient knows there is image content there.
So you should use the alt-text to either describe your image or the action you’d like people to take when they see the image. How do you add alt-text?
In the Email Canvas or Salesforce Mail Template options found with VerticalResponse, we prompt you to create Alternative Text for an image after you select to add it to the email.
If you write your own HTML, you can add alt text by entering the img alt=”description” attribute as part of your img src tag.
Keep the File Size Small - You should try to keep the file size of every image in your email below 30k. The smaller the file size, the faster the image will load for your recipients.
You can check the file size of any image you’ve uploaded to your library simply by looking directly beneath the thumbnail for that image. If you notice the file size is larger than 30k, simply scroll over the image and click the pencil icon to access our image editor.
Any image edited and saved with our editor is optimized for web use to make the file size as small as possible. So all you have to do is make a slight change to the image, save it and we’ll significantly shrink the file size automatically.
Turn Your Images into Links - Images are fairly big, pretty and tempting to click on. Turn them into links, so they can lead people back to your website.
To turn an image into a link using our Canvas editor just select the image, click the chain link icon in the toolbar, enter the web address to which you want to link and click submit.
Use Your Resources - VerticalResponse provides a free stock photo gallery with more than 75,000 images. To access this gallery, you need to use the Media Library link found in the Tools & Resources section on the main page of your VR Email tab. There is a link to the Stock Photo Gallery within the main Library page from where you can search for images that fit the needs of your email message.
