    Therefore, DNS is the most critical internet service. It’s like a custodian on the internet. From web content to email, all the internet services depend upon DNS functioning.

    Each device on the internet has a unique numeric identifier, called an IP address that other devices use to find that particular device.

    DNS servers erase the need for humans to memorize IP addresses such as or more complicated newer alphanumeric IP addresses 2001:4860:4860:0:0:0:0:8844 .

    The purpose of DNS is to perform the DNS resolution process involving converting a human-friendly domain name to its computer-compatible IP address .

    The IP address is assigned to each device on the internet, and it’s like a street address used to find the particular address. When someone types a domain name in its browser bar, the DNS servers translate it into a computer-friendly address to locate that webpage on the internet.

    How Do I Validate My Domain

    Validating your domain will improve the deliverability of your emails. Email service providers are less likely to send your emails into spam if they see that the ‘From email address’ is associated with a domain.

    1. Click the dropdown next to your name and select Settings

    2. Click on Domains

    3. Add your domain to the text box and click ‘Add Domain’. Do not add your full URL. For example, if we wanted to validate the SendFox website, we would use and not our full URL that is .

    4. When you have added the URL, click on the ‘Validate’ button that will appear in the new table with your domain.

    5. You will be redirected to a page with CNAME entries that you will need to copy into your web host’s DNS settings. Each web host provider is different so we recommend checking their knowledge base for instructions on how to add CNAME entries to your DNS settings.

    Validate Conditions And Throw Exceptions

    The following code example shows the simplest approach to validation in a domain entity by raising an exception. In the references table at the end of this section you can see links to more advanced implementations based on the patterns we have discussed previously.

    public void SetAddress

    A better example would demonstrate the need to ensure that either the internal state did not change, or that all the mutations for a method occurred. For example, the following implementation would leave the object in an invalid state:

    public void SetAddress

    If the value of the state is invalid, the first address line and the city have already been changed. That might make the address invalid.

    A similar approach can be used in the entity’s constructor, raising an exception to make sure that the entity is valid once it is created.

    Troubleshoot Email Domain Verification

    If you’ve followed the steps to verify your domain, but you haven’t received your domain verification email, there are a few things that may be happening. Here are some tips to help you troubleshoot.

    • Allow more time Depending on internet traffic and how busy your ISP is, it can take a couple hours for emails to arrive. This is more likely to happen around holidays and peak sending times.
    • Resend to a different address You can try resending the verification message to a different email address with the same domain. We’ll verify the domain if we can confirm that you manage the domain via one of the addresses provided.
    • Add us to your safe senders list Add to your safe senders list. This is the address the verification email comes from and this will help prevent the email from being mistakenly blocked or marked as spam.
    • Allowlist Mailchimp’s IPs Ask your IT team to allowlist Mailchimp’s delivery IPs. Allowlisting tells your mail server to allow any emails sent through our servers to be delivered . Usually, this is the first time your domain receives mail from Mailchimp and it’s possible that your receiving server is dropping the incoming mail because it doesn’t recognize Mailchimp’s IPs.
    • Use the most recent emailIf you’ve requested domain verification more than once, you might receive multiple copies of the same email from us. Make sure you use the most recent email to verify your domain. Otherwise, verification won’t work.
