Custom domain in Zoho Sign

Custom Domain in Zoho Sign

Available in all data centres and only in the Enterprise edition with more than 10 user licenses. 

With Zoho Sign, you can configure a custom domain, enabling you to replace the default Zoho Sign URL with your business domain, reinforcing your brand identity and improving user trust.

What is a custom domain?

Custom domain is a personalized branded label that allows you to customize your portal's URL to match with your brand's website URL. 

For instance, let's assume that you are part of a company in which you are responsible for managing onboarding forms and policy documents. Before setting up the domain mapping, your URL might look like: sign.zoho.com. The name of your company is Zylker Corporation, so after domain mapping, Zoho Sign will be accessible from sign.zylker.com. This reinforces your brand identity, making sure that all business transactions go through one domain and ensures that the signing requests are not overlooked and lead to delays. 

How to set up your custom domain in Zoho Sign 

This action can only be performed by administrators. If you are an administrator:
  1. From the Zoho Sign dashboard, hover over Settings and click Branding.



  2. Select Custom Domain.



  3. Enter your domain name.



  4. Copy the CNAME value.
  5. Go to your domain provider and add the CNAME value in the DNS manager.
  6. Click Verify and initiate the SSL request.



    Once your domain has been verified, the custom domain will be enabled. 



Installation of SSL certificates in a custom domain

SSL Certificates establish a safe connection between your web server and a user's browser by enabling your website to use HTTPS. Installing a SSL Certificate on your custom domain will also prevent access errors for your customers.

Once your domain name is verified, we will initiate the installation of a multi-domain SSL certificate for your custom domain. This process typically takes 3–5 business days. An SSL certificate enables HTTPS on your domain, ensuring a secure connection between your server and the user’s browser—helping prevent access issues and enhancing user trust.

Once it is installed, you can access the customer portal with your customised domain name. You’ll be notified via email when the SSL Certificate is installed.

FAQs/ Troubleshooting questions

  1. Who can set up the custom domain in Zoho Sign?
    Only Administrators can configure custom domains in Zoho Sign.

  2. What does a customized domain URL look like?
    Before setting up custom domain, your the url might look like: sign.zoho.com. Let us assume that the name of your company is Zylker Corporation. After you configure your domain, Zoho Sign will be accessible from sign.zylker.com.

  3. Is there any credit consumption associated with custom domain?
    No, credits will not be consumed for custom domain.

  4. Why isn’t my Custom Domain working after configuration?
    There may be multiple reasons that your custom domain functionality stopped working. Here are the things you can do to find out why:
    1. Go to zohomail.tools, enter the customized domain. Select the CNAME tab and click Lookup. If there are no records, check the TTL or wait until the entry is populated.



    2. Check if there is a valid SSL certificate for your custom domain. To verify SSL is installed properly, open https://<custom domain>. There should be a green tick if it opens in the browser.
    3. Check whether the license requirement is matched for your Zoho Sign account. If you need any more support or instructions, reach out to us via support@zohosign.com.

  5. Can I use a root domain (like yourcompany.com) instead of a subdomain (like sign.yourcompany.com)?
    We recommend creating and mapping a subdomain to Zoho Sign in order to use this feature. While it is technically possible to point your root domain to Zoho Sign, doing so is not advised, as it goes against standard DNS best practices.

  6. Can I change my customised domain after setting it up?
    Yes, you can change your domain after setting it up. However, you are only allowed to have one domain mapping set up at a time. This means you will have to delete the current domain mapping set up and create another one.
