# Why should I configure a sending domain for an email signature tool? ### Why DNS? When you set up a signature in Scribe, it contains numerous URLs (such as logos, profile pictures, icons, website addresses, etc.)\ \ To track the conversion rate from your signature's marketing elements, all these URL domains are shortened using our default domain, sendassets.io.\ \ While you can retain this domain, it's not the optimal choice. Spam filters tend to flag emails containing numerous URLs that point to a different domain than the sender's email domain.\ \ That's why we offer the option to replace this default domain with a subdomain from your primary domain. This subdomain is referred to as a sending domain.\ \ For instance, if your email address is you can configure a sending domain such as `email-signature.my-company.com` to keep spam filter content. {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
