To use a domain in promio.connect as sender domain, you need to register it with your provider.
Add the domain under Settings > Domains as sender domain to generate and display the records to be entered at your provider for this domain.

We recommend sending newsletters with your own sender domain. A sender address that can immediately be associated with your company creates trust in the recipient and can have a positive effect on the open rate.

You should use a domain or subdomain that is used exclusively by promio.connect as sender. Multiple use of domains / subdomains may lead to incorrect delivery of emails.
If you want to use your main domain – the same one used for corporate communication – as sender domain, then you have to define a subdomain for this domain, which is reserved for use by promio.connect only. I.e. the recipients receive your newsletter e.g. from info@mail.yourCompanyDomain.com or info@newsletter.yourCompanyDomain.com

By clicking the green button on the bottom right you create a new domain.

Domain:
Enter the preferred sender domain. The domain is used as sender domain for your mailings.

Redirect URL:
Enter a corresponding redirect URL. Make sure to enter it including the http protocol - the system automatically switches to https. The redirect URL is used for link tracking within your mailings.

Choose the configuration method. If your sender domain is not a subdomain, only the Advanced method is possible.

Simple: Choose this method if your domain is a subdomain and is used exclusively for sending e-mails in promio.connect and is not already in use elsewhere (e.g. as a domain for a website).
Advanced: Choose this method if the sender domain is already in use as a domain for a website or you want to have full control over all DNS settings.

Save the domain through the fee-based registration in promio.connect.

After registration, you will be taken to an overview that lists all DNS records to be done at the provider:

• System settings:
  This setting is done automatically by promio.net. Note that the required changes will take about 24 hours AFTER the DNS records have been successfully validated.

• CNAME - Sender domain:
  Only necessary with configuration method “Simple”.
  Add the CNAME specified under “Expected” to the DNS records of your new sender domain.
  For verification purposes, you will see a comparison between the given entry and the one you may have already made.

• DKIM:
  The usage of DKIM improves the deliverability of your newsletters and is obligatory for sending via promio.connect.
  First create the required subdomain, and then add the TXT record (public key) specified under “Expected” to the DNS records of this subdomain.
  For verification purposes, you will see a comparison between the given entry and the one you may have already made.

• MX Records:
  Only necessary with configuration method “Advanced”.
  Add the servers listed under “Expected” as MX records to the DNS of your new sender domain. All of these records should have the same priority, e.g. 10.
  For verification purposes, you will see a comparison between the given entries and the ones you may have already made.

• SPF:
  Only necessary with configuration method “Advanced”.
  Add the TXT record specified under “Expected” to the DNS records for your new sender domain.
  For verification purposes, you will see a comparison between the given entry and the one you may have already made.
  Usage of SPF improves the deliverability of your newsletters, especially in foreign ISPs.

• CNAME - Redirect URL:
  Enter the CNAME specified under “Expected” into the DNS records of your new redirect domain.
  Also note that the sender domain cannot be used as redirect URL at the same time! When the redirect domain was used for a longer while the A-records might be set. Only with an active A-Record a redirect domain may be the same as the sender domain.

• DMARC:
  Using DMARC is optional, so sending with this domain is also possible without using DMARC.
  Add the TXT record specified under “Expected” to the DNS records of the shown subdomain to your DNS to optimize delivery speed and deliverability.
  You may list multiple addresses comma-separated within the TXT record in the mailto - the address of sender domain should be listed first.

You can also check changes to the DNS entries, for example, using the following online tool: http://network-tools.com/default.asp?prog=dnsrec&host=INSERT.YOUR.DOMAIN.HERE

After all changes are done correctly and completely, every item return an “OK”. If an error comes up at one of the items please adjust the corresponding DNS entry.

If you have questions, please contact our support team by opening a ticket in the service center.

A system side redirect forwards all e-mails sent to addresses of your sender domain to the indicated target address - which is not visible to the responder. Thus - in contrast to the functionality of a reply-to address - e.g. all automatic replies or replies created by copying the from address and then opening a new e-mail are also forwarded.

By default, e-mails to the sender domain are ignored. You can activate forwarding of these e-mails to any e-mail address via the action “Edit system side redirect”. Make sure that the entered e-mail address exists and that your company has access to the corresponding mailbox.

Under Settings > Domains you will find an overview of all domains registered in promio.connect:

In the Status column you can see whether the DNS entries at the provider of the domain are all valid.

• Green icon: DNS settings are correct and the domain can be used for delivery.
• Yellow warning icon: There are DNS records that should be updated. You can get further information in the detailed view of the domain. The domain can still be used for delivery.
• Red warning icon: There are incorrect DNS entries. In the detailed view of the domain you get hints about which problems occur. The domain cannot be used for delivery.
