Configuring your DNS settings

We use a subdomain to send your emails so that your organizational (brand) domain is visible as the clients would expect to see it. Variations of your brand domain (such as yourdomainnews.com) are classic methods that phishing and spam emails use to trick recipients, and should therefore be avoided.

In all the examples below we use the following convention: prefix.subdomain.yourdomain.com, 

where:

• prefix = the prefix for link and image domains that we provide
• subdomain = your preferred subdomain
• yourdomain = your brand domain
• .com = your top-level domain (it could also be '.net', '.co.uk', etc.)

When you change to Emarsys from a previous service provider, you will need to change your sender domain. This will enable you to continue to send the bulk of your emails with your previous provider while we are ramping up your reputation with the new domain. You can then migrate the remaining campaigns to Emarsys and ensure a smooth handover.

We will normally use your subdomain as the sender domain, without an additional prefix.

Remember that the subdomain is what your customers will see in the From address of the emails you send them (e.g.: info@subdomain.yourdomain.com). You should therefore give it a name that fits the purpose and is easily identifiable to your customers, for example 'email' or 'webshop' (do not use 'emarsys'!).

If you are configuring your own link and image domains, keep the prefixes as short as possible as this will have an impact on the size of your emails.

If you have multiple Emarsys accounts, you can use the same sender domain for all of them if you wish. This will not affect reply mails, as we use an internal ID to make sure each reply mail is directed to the correct account. 

However, there are some good reasons to have multiple sender domains, and this is the perfect opportunity to create them. 

• Many ISPs recommend separate domains for separate email types (e.g. for customer acquisition campaigns, for customer lifecycle campaigns and for operational emails), so that your sending behavior is consistent per domain.
• You might also want to have different subdomains per brand, language or even department.
• You will might also want to consider a separate sender domain if you are using our Triggered Email product.

We will use your subdomain as your sender domain, unless you require a prefix.

We will also use your subdomain to define a link domain, such as link.email.example.com. All the tracked links in your emails will be routed via this domain.

We also define an image domain, such as images.email.example.com. If you are hosting your images with Emarsys, this subdomain will point to where they are hosted and will enable you to take advantage of Emarsys’ global content delivery network (CDN).
