Image Blocking

What is image blocking?

Image blocking is a technique used in email marketing to prevent images from being displayed in the email client. This is done by setting the image’s src attribute to “none” or by using an inline CSS style to set the display property to “none”. When the email is opened, the images will not be displayed, but the text will still be readable by the recipient. This is a way to reduce the amount of data that needs to be downloaded, which can improve performance and help to avoid spam filters.

What are the benefits of image blocking?

There are a few benefits to image blocking. It can speed up the loading of emails for your subscribers reducing the time taken for reading the email. This is because images often take longer to load than text, so by blocking them, you’re ensuring that your subscribers will be able to see your email as quickly as possible.

Image blocking can help you to avoid being flagged as a spammer. Many email providers look at how many images are in an email and if there are too many, they may assume that the email is spam and remove it from recipient’s inbox. By blocking images, you’re reducing the chances that your email will be flagged as spam.

It can also help to protect your subscribers from potential security threats. Many malware and virus attacks are delivered through images, so by blocking them, you’re helping to keep your subscribers safe.

What are the risks of image blocking?

There are a few risks associated with image blocking. If your images are blocked, your recipients may not see the important information or call to action that you included in your email. This could lead to them not taking the desired action, such as clicking through to your website or buying your product.

Blocked images can make your email look unprofessional or spammy, which could lead to recipients unsubscribing from your list or reporting your email as spam. It can also lead to less conversions.

How can you prevent image blocking?

There are a few things that you can do to prevent image blocking in email marketing:

  • Use a reputable email marketing service that will automatically encode images in a way that prevents them from being blocked.
  • Make sure that all of your images are hosted on a reliable server that is not likely to be blocked by spam filters.
  • Use alternate text descriptions for your images, so that even if they are blocked, the recipient will still be able to see what the image is.

What are the consequences of image blocking?

There can be a few consequences of image blocking, the most common of which is that potential customers may not be able to see the images in your email, which could impact their decision to either open the email or buy from you. If your email’s images are blocked by a spam filter, it could end up in the recipient’s spam folder, which means they may never see it.

How can you optimise your images for email marketing?

There are a few things that you can do to optimise your images for email marketing:

  • Make sure your images are the correct size. If they are too large, they will take longer to download and could end up being blocked by email clients.
  • Use compressed images. This will help to reduce the size of the file and make it quicker to download.
  • Use the correct file format. Most email clients support JPEG, PNG and GIF files, but be sure to check the specifications of your chosen email client to make sure.
  • Include a text alternative. If your image is not displayed, the text alternative will be displayed instead. This is especially important for infographics and other types of images that contain a lot of text.
