Configure your sending domain

Step-by-step guide to set up a custom sending domain in Scribe for better email deliverability.

This guide walks you through configuring a custom sending domain so all your signature URLs use your own company domain instead of Scribe’s default (sendassets.io).

Set up your sending domain

1. Go to the DNS tab

   Go to Configuration → DNS in the left sidebar.

2. Add or select your domain

   If you’ve already synced your email provider (Google Workspace or Microsoft 365) with Scribe, your domain will appear automatically. Click Configure to proceed.

   If your domain isn’t listed, click Add a domain and enter your company domain (e.g. mycompany.com).

3. Choose your subdomain prefix

   Pick a prefix for your sending domain. This will be combined with your company domain to create the full sending domain.

   For example, if you enter signature and your domain is mycompany.com, your sending domain will be signature.mycompany.com.

   Common prefix choices:

   • signature
   • email-signature
   • sig
   • mail
4. Configure the CNAME record

   Scribe will display two CNAME records that you need to add in your domain provider’s DNS settings.

   Record type	Host Name	Required Value
   CNAME	Your chosen prefix (e.g. email-signature)	custom-hostname-ass... (provided by Scribe)
   CNAME	_acm... (provided by Scribe)	email-signature.scribe-... (provided by Scribe)

   Use the Copy button next to each value to copy it exactly.

   You have two options to configure them:

   Option A — Automatic setup (recommended)

   Follow Scribe’s setup wizard to automatically configure the DNS records in your domain provider. No developer needed — Scribe handles the configuration for you.

   Option B — Manual setup

   If automatic setup isn’t available for your provider, you’ll see the two CNAME records with copy buttons. Manually add both records in your domain provider’s DNS management panel (e.g. GoDaddy, Cloudflare, Google Domains, OVH, Namecheap, etc.).

   Once you’ve added both records, click I have copied 2/2 records to proceed.

   Need help? Click Forward instructions to a colleague to generate a shareable link. Send this link to your IT team or whoever manages your domain — they’ll be able to complete the DNS setup without needing access to Scribe.

5. Wait for DNS propagation and verify

   DNS propagation can take up to 48 hours. Once the DNS records have propagated, the status in Scribe will automatically change to Validated.

   You can check the propagation status at any time:

   • In your Scribe DNS settings page
   • Using an external tool like DNS Checker

Once validated, all signature URLs across your workspace will automatically use your custom sending domain instead of sendassets.io. No need to update individual signatures.

Cloudflare users — If your domain is managed through Cloudflare, make sure to:

• Set the Proxy Status to DNS only (gray cloud icon, not orange).
• Disable CNAME flattening in your Cloudflare DNS settings.

Failing to do so will prevent Scribe from verifying your sending domain.

Frequently asked questions

What subdomain should I use?

You can use any subdomain you like, as long as it’s not already in use. We recommend something descriptive like signature.your-company.com or email-signature.your-company.com. Avoid using your root domain (e.g. your-company.com) — always use a subdomain.

How long does DNS propagation take?

DNS changes typically propagate within a few minutes to a few hours, but in rare cases it can take up to 48 hours. If verification hasn’t completed after 48 hours, double-check that both CNAME records are correctly configured.

Can I change my sending domain later?

Yes. You can update your sending domain at any time from the DNS settings page. You’ll need to add new DNS records and verify them. All signature URLs will automatically switch to the new domain once validated.

Can someone else configure the DNS for me?

Yes. During setup, click Forward instructions to a colleague to generate a shareable link. Send this link to your IT team or domain administrator — they’ll see the exact records to add without needing a Scribe account.

Does this affect DKIM or SPF?

No. The sending domain is used for signature asset URLs and tracking links, not for email authentication. DKIM and SPF are separate configurations managed through your email provider. Scribe also offers DKIM signing for marketing banners — see the Plans comparison for availability.
