Link & Image Validation

What is link validation?

Link validation confirms the legitimacy and functionality of the links in your emails. This process works by double-checking that the URL used is correct, that it loads correctly, and that recipients end up in the right place.

What is image validation?

Image validation ensures that the images in your emails are accessible, include required attributes, and have CSS styling. One component of this involves checking the HTML parameters of the images in your emails to ensure they display correctly for every recipient.

Both affect your email's deliverability, as broken links or images can trigger spam filters. Testing the validation of your content before sending it to your recipients is a Deliverability Best Practice.
