Email, domain settings and complaints 

In this section, you have access to ExpertSender settings. 


Here, you can enter the information necessary to be able to send emails via ExpertSender: 

  1. Domain settings
    • Sending domain – The address from which emails sent via ExpertSender originate. The sending domain is set up when you create your business unit, so you cannot edit this field. 
    • Default domain for links – The address for links included in your emails, including unsubscribe and system links. This domain is set up when creating your business unit, but you can change it here. 
  1. Sender settings – Enter the names and email addresses that will appear in the headers of your messages sent via our platform. The same data will appear in the basic email settings in the message editor – you can, of course, always change them:
    • Default “From” name – Enter a name that your customers will easily recognize, e.g., Anna from
    • Default “From” email – Enter the email address from which your messages will be sent.
    • Default “Reply-to” name – Enter the name of a person your customers should contact if they wish – it may be the same as in the From field.
    • Default “Reply-to” email – Enter the email address to which your customers can send their replies.

Remember to save your changes.

Domain authentication 

Here you can access information about email channel statuses and DNS settings.  

To learn how to set up DNS, read this article: Configuring the email channel.

Depending on the current configuration step, the email channel status may show the following status: 

  • Configure DNS records – Sending emails is not possible yet, DNS records need to be set up first. 
  • Configuration in progress – ExpertSender team completes channel configuration. 
  • Active – The channel is working and you can send emails.

What are DNS records? 

DNS records are used to transfer information between your clients, your websites, and the servers where information about your website is stored. 

Let’s start with what DNS is. DNS (Domain Name System) is a protocol that translates the domain name of your store, e.g.,, into computer language, i.e., numerical data. 

In the DNS Settings table, you can see a list of sending domains and link domains along with the following information: 

  1. Status – Indicates whether the DNS settings for a given domain are correct. Its possible statuses are: 
    • Wrong value (in red) – It means the domain entered in the Value field is incorrect. It should be identical to the domain entered into the Name field. 
    • Record not found – DNS record has not been added to your hosting service. 
    • Domain does not exist (in red) – It means the entered domain may contain a typo, or it simply does not exist. 
    • Verified (in green) – It means verification of DNS settings for this domain has been successful. 
  1. Name – Displays the names of all domains available in the business unit. 
  1. Type – Displays record types for a given domain. 
  1. Value – Displays, e.g., IP address or server address. 

You can use the Check now button to verify the DNS Settings you have entered. Verification may take up to 48 hours and returns one of the statuses described in point 1.

Domain family 

Here, you can manually set the distribution of IP addresses for domain families. You can use local or general domain families, such as Google, Yahoo/AOL, 

In ExpertSender you have the following address types at your disposal: 

  • Dedicated IP – Addresses used only by a single business unit. Regardless of quantity assigned, all addresses are charged equally with email delivery. We display all dedicated IP addresses in full form. 
  • Shared IP – Shared addresses assigned to different business units. Regardless of the number of assigned addresses, only one name is displayed on the list. 
  • Premium IP – Special addresses dedicated to deliveries to WP/o2, Onet or Interia. All deliveries to these domains are set to 100% by default. Regardless of the number of assigned addresses, only one name is displayed on the list.

Distribution of email sending to IP addresses 

Each domain family has IP addresses assigned to them from which you send your emails. If you have more than one IP address assigned to a given domain family, you can distribute email sending among them in a way that suits you. For example, you can delegate 75% of sending to one address and the remaining 25% to the other. 

You can also charge all IP addresses with the same volume – simply click the Distribute evenly button. 

When using a new dedicated IP address, start by sending emails slowly and gradually increase the volume.

This helps establish a positive reputation with Internet service providers, ensuring that your emails land in recipients’ primary mailboxes rather than spam.

You can distribute email sending in three ways: 

  1. When providing the total distribution for all addresses in a given domain family – enter the percentage value in the Total window. 
  1. To charge the shared IP addresses with the same number of deliveries – click the Distribute evenly button. 
  1. Manually – using the slider visible next to each IP address, or entering the percentage value in the box to the right of the slider. Click the padlock next to the selected IP address to exclude it from the previously described settings.


Here, you can decide how to deal with customer email addresses that do not respond in the desired way to your messages. Such an undesirable reaction – or a complaint – may be the so-called email bounce, or constant failure to open your messages.

Deciding how to deal with an unresponsive email address allows you to maintain the address database in good condition and to keep a positive sender reputation.

Complaint Settings:

  1. Set the number of complaints for your messages sent to each email address.
  1. Decide what will happen to this email address – you can choose from the following options:
    • Add email to blocklist.
    • Revoke selected consents – select consent from the drop-down list.
    • Do nothing – unresponsive email addresses will continue receiving your email messages.
