When you set up a signature in Scribe, it contains numerous URLs: logos, profile pictures, social icons, website links, banner images, and more. To track clicks and conversions from your signature’s marketing elements, all these URLs are shortened using Scribe’s default domain: sendassets.io. While this works, it’s not optimal. Spam filters tend to flag emails that contain many URLs pointing to a domain different from the sender’s email domain. That’s why Scribe lets you replace this default domain with a sending domain: a subdomain of your own company domain.
For example, if your email address is joe@my-company.com, you can configure a sending domain like email-signature.my-company.com so all signature URLs match your company domain and pass spam filter checks.

​
Benefits of a custom sending domain

Setting up a custom sending domain improves your email deliverability in three ways:
  • Avoids spam filters: Emails with links matching the sender’s domain are far less likely to be flagged as spam.
  • Builds trust: Recipients and email security tools see consistent, branded URLs instead of a third-party domain.
  • Protects your sender reputation: Your signature URLs are tied to your own domain rather than a shared domain used by other Scribe customers.

​
What happens if I don’t configure one?

Your signatures will continue to work using Scribe’s default domain (sendassets.io). However, emails may be more likely to trigger spam filters, especially for recipients with strict email security policies.
