Boost Deliverability with Optimal Text-to-Image Ratio in Emails
As an email marketer, you need to take care of a lot of things. Apart from writing engaging and relevant content, you need to add design elements to please the viewer’s eyes. But, the most important thing is to get your email DELIVERED to your subscriber’s inbox – while ensuring you have respectable open and click-through rates.
Emails should be designed and coded by keeping the concern of email deliverability in mind. Most ISPs look through the keywords that indicate whether the emails are spam or not. And hence, image heavy emails without much text can raise a red flag for the spam filters.
Although different spam filters have different criteria for a healthy balance of text and graphics, it is recommended that the marketers maintain a proper text-to-image ratio to ensure their emails sail through the spam filters and land in the viewer’s inbox successfully.
Recently, Mailchimp in their blog recommended to follow an 80:20 text to image ratio in emails, i.e., 80% text and 20% images.
Why is Maintaining the Image-Text Ratio in Emails Important?
‘Image only’ emails go into SPAM
Spam filters block image-only emails. Spammers can hide secret links or content in the mail by sending image heavy emails so that their content is not recognized and read by the spam filters. And so, any email with no healthy balance of text and images is sure to get rejected by the spam filters.
Images maybe ‘turned off’ by viewers
Some users and email clients generally keep the images turned off at their end. If the image is blocked, the email will appear to be either incomplete or completely blank. Such emails are likely to be ignored, marked as spam and even unsubscribed.
When there are more images and less text in an email, the images may take more time to load depending on the browser and internet connection of the user and hence may not convey the entire message of the email. Emails with images that take more time to load have lesser click-through rates and conversion rates.
Take a look at this email from Shopbop!
All the information about the offers and CTA are contained in the image. And when the images are turned off, the same email appears as below:
Here, the alt tags serve the purpose of conveying the message of the email. But it is essential to maintain a ratio so that the message is conveyed in a better way.
How to make sure your Email gets delivered?
Email marketers need to bear in mind the following points while planning an email campaign:
- 80% of the email should be text.
- Images should cover only 20% of the email.
- The images should compulsorily have alternate text (alt tags).
- Avoid the concept of ‘one image will serve the purpose of the email.’
- Emails without a balanced text-image ratio won’t allow the users to search for it after a certain period.
- Test your email well and see how it appears in different clients.
