To send more than 100,000 email messages through marketing campaigns in a 30 day period, you must set up a campaign domain. Similarly, to send more than 10,000 email messages in any single campaign event (blast), you must also set up a campaign domain.
Users may experience getting "Undeliverable Campaign Email (Exceeded Limit)" even if they haven't used up the provisioned Campaign Email Volume on their account if the number of recipients exceeds the limit in a 30-day period or in a single campaign event when Campaign Email Domain is not setup.
To set up your email domain name in NetSuite:
Go to Setup > Site Builder > Setup Tasks > Domains (Administrator).
In the Domain Name column, enter the domain name you have registered to send campaign email messages.
In the Hosted As column, select Email Campaign.
Repeat these steps for each email domain you want to add.
NOTE: After you create a new domain or update an existing domain, you must wait two hours before you configure DNS settings with your domain provider.
7. After two hours, return to the Domain Setup page, and then copy the CNAME (Alias) NetSuite assigned to you. You will use this CNAME to complete DNS setup with your domain name provider.
Go to Setup > Site Builder > Setup Tasks > Domains (Administrator). If you use SuiteCommerce Advanced, go to Setup > SuiteCommerce Advanced > Domains.
8. (Required) Visit your domain provider's website to complete the CNAME record setup. See Set Up a CNAME Record.
9. Select the campaign domain on the Marketing subtab of your email template or campaign template records.
You can set a default domain for your templates under Setup > Marketing > Preferences > Marketing Preferences (Administrator) > Default Campaign Domain field.
After you set up domain names in NetSuite, and configure DNS settings with your domain provider, your domains should begin redirecting. The time frame for domain redirecting depends on your DNS provider. Generally, this process takes between two to 48 hours.
