Step 1 - Go to your Scribe settings and click on the "Domains" menu.
Your domains have already been imported from your email provider.
Step 2 - Click on the pencil icon and add a sending domain of your choice.
You have to do that for each active domain.
Step 3 - Configure your DNS
To do that, you need to add a CNAME record in your domain DSN zone (GoDaddy, Gandy, Cloudflare, AWS Route 53, OHV, ...)
This is the configuration we did for Scribe in CloudFlare:
Go to your host provider
For Cloudflare click on the DNS tab
In Name write any value like → signature-assets
In Target write → cname.scribe-mail.com
You can check the propagation of your DNS in your Scribe settings or on the link below:
Make sure to have DNS only in Proxy Status.
Make sure to disable CNAME flattening.
