Email signup friction refers to any obstacle or difficulty that users may face when trying to sign up for an email newsletter or list. This can include various barriers, such as a lengthy registration form, the need to create an account, or a lack of transparency about how the user's data will be used.

Friction can also arise from technical issues, such as slow-loading pages, broken links, or confusing navigation. When users encounter these obstacles, they may be less likely to complete the signup process, which can hurt a company's marketing efforts.

Reducing email signup friction is important for businesses that rely on email marketing as a way to reach and engage with customers. By simplifying the signup process and minimizing obstacles, companies can increase the number of subscribers they attract and improve the effectiveness of their email campaigns.
