Email campaigns are a great way to reach out to potential customers and promote your products or services. However, if you’re not careful, your email campaign can quickly become a source of frustration for your recipients. One common annoyance is the 404 error page. This occurs when someone clicks on a link in your email that leads to a page that doesn’t exist. Not only does this cause confusion for the recipient, but it also reflects poorly on your brand. To avoid this problem, be sure to double-check all of the links in your email before sending it out. You should also consider setting up a custom 404 error page on your website. This will help to ensure that visitors have a positive experience, even if they do accidentally click on a broken link.
