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.
