Common email subdomain errors

What would you like to know?

• Subdomain not propagating
• Email not delivered and/or not sent
• Same subdomains

Below are some checks that you can run if you notice that your subdomain is not propagating and/or you are receiving an error message, even after waiting 72 hours:

Subdomain not propagating

Before you send an email campaign or publish your landing page, CNAME records must be propagated. To confirm that the propagation has taken place, you can use a tool called What's My DNS.

To search for records in What's My DNS, follow the step-by-step instructions below:

1. Enter your subdomain in the first field. 
2. Select the CNAME record type in the second field.
3. Click the gear icon and fill in the Expected value field with the corresponding record value. This procedure will check the propagation of the inserted value on several DNS servers. See the example below:
   
   

If all the check marks are green, as in the example above, it means that the records have been propagated. In this case, you can validate your subdomain in RD Station Marketing and start sending email campaigns and publishing your landing pages.

If a status displays Propagation Check Failed, it means that they are still not 100% stable. This is an expected behavior, since it takes a certain period of time for your server to fully propagate these records to all other servers.

However, if the records are not propagated after the time period, you should contact your DNS server, which is responsible for the operation and propagation of records. RD Station Marketing only performs the query of these statuses. We do not have access to your DNS server to perform analyses. Therefore, the best thing to do is to contact your server in order to find out in detail why the propagation is not occurring. 

Email not delivered and/or not sent

• Setting up two or more subdomains and connecting them to the same domain

See the example below:

subdomain@yoursite.com 
subdomain2@yoursite.com

In this example, we have two different subdomains that are linked to the same domain - @yoursite.com. This setup may cause conflicts in RD Station Marketing as it uses the same sender domain, which may lead to a deliverability error. In other words, some of the leads' email servers may direct the campaigns to the SPAM folder.

The solution in this case is to delete one of the subdomains, preferably the one that is not yet propagated. See the step-by-step guide below:

1. Go to Account > Settings in RD Station Marketing.
2. Select the option Domains.
3. In Email, click the button Delete this configuration.
4. Done. The non-propagated subdomain will be deleted.

• Sending email campaigns before propagation is complete

We do not recommend sending emails before propagation is complete.

Subdomain settings are very important to maintain the integrity, authority, and security of your domain while sending campaigns. Since RD Station Marketing is not yet authorized to use the domain you are configuring, with its information and reputation, some of the leads' email servers may send campaigns to their SPAM folders. This is because email servers will identify that there is no authorization for the use of this sender domain, and may consider the email SPAM as a way to protect users.

Same subdomains

You cannot configure the same subdomain for both Landing Page and Email, as this creates a conflict in RD Station Marketing.

To resolve this issue, simply reconfigure one of the subdomains, either Landing Page or Email, by clicking the Review instructions button:
