To establish a good sender reputation and minimize the risk of your email campaign ending up in a spam or clutter folder, in the Email Experience Manager you can validate the domains that you want to use to send email campaigns.
In addition to authorizing the domains, you can warm up your domains
When you use Sitecore Email Cloud, you only need one option for validating a sending domain and DKIM (DomainKeys Identified Mail) is the best method. You do not have to set up an SPF record for your sending domains, but you can implement it in your custom SMTP setup.
When you use Sitecore Email Cloud, it provides a DKIM record for each of the sending domains that you configure. The DKIM records enables the Internet Service Providers (ISP) that receive your email campaigns to verify the authenticity of the email campaign by comparing the sender domain against the authorized list of domains. This helps to keep your email campaigns out of spam folders and it ensures that others cannot use your domain without permission.
The custom SMTP provider does not support this functionality. To use this functionality, you must use a provider that supports it.
To add a new domain:
- In the EXM menu, under the Administrator section, expand Email Delivery Service and click Domains.
- Click Domain , and then click Add.
- In the Add Domain dialog box, enter the name of the domain. You can use the format domain.net or an IP address, for example, [18.104.22.168].
- Click Next. The system validates the domain's DKIM records. If the domain does not have a DKIM record or if they are set up incorrectly, a warning message appears.
- Click Finish.
- From the Domain menu, you can:
- Click Show details, to see the required DKIM setup information for a selected domain.
- Click Delete, to remove the selected domain.
