UFOSend definitive guide to SPAM-free email [Part 1]


To reach your audience in their email inboxes rather than SPAM folder, you have to design the email with cautions, especially for the eye-catching images which you must have paid lots of effort on. What if your compelling images make your email into SPAM folder or even being blocked by internet service providers [ISP]? Here are 3 tactics of how to put images in your email in order to get rid of SPAM.


  •  Do not use only one large image without text 
Never use only one large image in email

Text is necessary to pass the threshold of SPAM filters as they will check if the email content contains meaningful content or SPAM message. SPAM filters will determine whether to put the email into recipients’ junk boxes or even block the email depends on the image and text used in email. Email with just one image cannot pass the checking definitely. SPAM filters will filter out email with one large image.



** Tip: SPAM filters are very smart to check if your whole email content is relevant to the subject. So make sure your email subject is consistent with the email content.

  •  Break the large image into different pieces 
Alternatively, break your large image into few pieces with text description in order to strike a balance between text and image in your email. I understand ambitious email marketers always want to use catchy images to grab readers’ attention once the readers open the email. Yet, the whole story ends if your well-designed email is blocked by SPAM filters.

However, do not include too many images in one email as more images means much loading time. Your readers won’t wait for the images and may delete your message immediately after open if they don’t find value from your email (**Email users only spend 15-20 seconds on searching valuable message in one email). Remember that there are too many reasons of broken images which can destroy your whole email. More images may also mean more broken images. SPAM filters may block the email with too many images too. 

Best ratio of images & text in email

The best ratio of text and images in email will be 80% : 20%. That is, 80% of the email should be text content while images should only be 20% of the email. Do not design the email with more than 25% image. Moreover, tune your image size before embedding to your email or more time will be taken to load the images. The images’ size and resolution should be limited within 600 px and 72 dpi so that the images can be displayed properly in mailbox.


  •  Use thumbnail 
You can put thumbnail in the email if you really want to include some attractive images. Users can click the thumbnail to view the web version of the email. Then, they can read the full message including the compelling images. You may also direct the readers to specific landing page which provides more relevant information. This tactic drives more click rate as well as traffic to your website.
