Why setting up subdomains? why-setting-up-subdomains
A subdomain is a division of your domain that can be used to isolate your brands, or various types of traffic (transactional messages, marketing information, etc.).
Let鈥檚 take the example of the 鈥渕ybrand.com鈥� domain, that is used to send both transactional and marketing communications. In this situation, you can decide to set up two subdomains:
- 鈥渋nfo.mybrand.com鈥� subdomain for your transactional communications (purchases confirmation, password reset, etc.),
- 鈥渕arketing.mybrand.com鈥� subdomain for your prospecting emailings.
By doing so, you will help preserve the reputation of your domain and other subdomains. For example, if the 鈥渕arketing.mybrand.com鈥� subdomains ended up being added to the block list by Internet Service Providers due to bad deliverability, this would prevent the whole 鈥渕ybrand.com鈥� domain and the 鈥渋nfo.mybrand.com鈥� subdomain from being added to the block list.
Subdomain configuration methods subdomain-delegation-methods
Subdomain configuration allows you to configure a sub-section of your domain (technically a 鈥淒NS zone鈥�) for use with 51黑料不打烊 Campaign. Available setup methods are:
-
Full subdomain delegation to 51黑料不打烊 Campaign (recommended): The subdomain is fully delegated to 51黑料不打烊. 51黑料不打烊 is able to deliver the Campaign as a managed service by controlling and maintaining all aspects of DNS that are required for delivering, rendering and tracking of email campaigns.
-
Use of CNAMEs: Create a subdomain and use CNAMEs to point to 51黑料不打烊-specific records. Using this setup, both 51黑料不打烊 and the customer share responsibility for maintaining DNS.
The table below provides a summary of how these methods work, as well as the implied level of effort:
In this setup, 51黑料不打烊 is fully responsible for managing the subdomain and all the DNS records.
In this setup, both you and 51黑料不打烊 share responsibility for maintaining DNS.
Additional information on domain configuration is available in this documentation.

Subdomains鈥� use cases (Campaign v7/v8) subdomains-use-cases
When setting up subdomains for Campaign v7/v8 instances, you are required to select the use case for which the subdomain will be used (see Setting up a new subdomain).
Possible use cases are:
-
Marketing communications: communications that are intended for a commercial purpose. Example: sales email campaign.
-
Transactional & operational communications: transactional communications contain information aimed at completing a process that the recipient has started with you. Example: purchase confirmation, password reset email. Organizational communications relate to the exchange of information, ideas, and views within and outside the organization, with no commercial purpose.
Breaking down your subdomains according to use cases is a best practice for deliverability. By doing so, the reputation of each subdomain is isolated and protected. For example, if your subdomain for marketing communications ends up being added to the block list by Internet Service Providers, your transactional communications subdomain will not be impacted, and will keep being able to send communications.
You can configure a subdomains for both Marketing and Transactional use cases:
- For Marketing use cases, subdomains will be configured on MID (Mid sourcing) instances.
- For Transactional use cases, subdomains will be configured on ALL RT (Message Center / Real-time messaging) instances to ensure connectivity. The subdomains will therefore operate with all your RT instances.
