Step 1. Choose the domain
In order to launch a campaign for the domain clientdomain.com, a prefix has to be specified, which will be used as a name of an authorization subdomain. The prefix may e.g. be "mail", so that in the case of clientdomain.com, the name of the domain will be mail.clientdomain.com.
Step 2. Authorization - DKIM
Then four CNAME records have to be added to the domain:
Their values are set up individually for each client.
Step 3. Domain authorization - SPF
Afterwards you need to modify the TXT record responsible for SPF authorization:
ATTENTION! Pleas take note of the already existing SPF records. They set out the list of servers allowed to perform sendings within a particular domain. An incorrect configuration may cause problems with message deliverability.
If a client has a new domain and doesn't perform any other sendings from it, the record will look as follows: "v=spf1 include:spf.ipresso.com ~all"
Step 4. Domain authorization - DMARC
You also need to modify the record responsible for DMARC authorization:
In the record's content, you can define the email address (firstname.lastname@example.org) to which the delivery and violation reports will be sent for the messages sent within the domain.
Step 5. Additional settings (optional)
If the domain chosen by the client clientdomain.com is a new one, and doesn't contain any specific records, you have to provide at least two records:
Value of the record A has to refer to the IP address chosen by the client, whil the MX record must contain the priority and address of the SMTP mailing server.
Step 6. Domain authorization - iPresso
After adding the records above, the clientdomain.com domain may be authorized in the iPresso system. In order to do it, please contact an iPresso's account manager and deliver to them the list of email addresses to be added to the domain.
A domain prepared in the manner specified above meets all the criteria set out by commercial email servers.
