How to Add and Authenticate an Email Domain

Adding and authenticating your own email domains means your emails will be sent from your own domain rather than one of our shared domains.

This both looks more professional for your subscribers, and also allows for better inboxing if one of our shared domains rarely gets blocked due to another customer.

Here's how to add your own domain.

Step 1:

Before you begin, you must make sure you are logged in to the MPZMail control panel. If you don't already have an account you can create a free account.

Step 2:

Click your name at the top right of the control panel, and then click Company Profile.

Step 3:

Click the "My Domains" tab towards the top of the screen.

Step 4:

You now have two options. You can either "Add and Verify a new Domain", or you can purchase a brand new domain directly.

If you choose to purchase a new domain it will be automatically setup, and we even automatically add Tracking and CDN subdomains, so you can skip the rest of the steps in this article.

If you are setting up an existing domain, click the "Add and Verify a New Domain" button.

If your domain is already listed on this page but has an "Authenticate" button on it please skip to step 6.

Step 5:

Once you have clicked the "Add and Verify a new Domain" button you will be asked to enter an email address at this domain. We will send an email to this email address to confirm you are authorized to use this domain name.

Once you have entered your email address click the "Continue" button and wait for an email to arrive. The email contains a link to click which will authorize your domain.

Step 6:

Your domain will now be visible on the control panel and you are free to start sending from this domain name. However, you will notice the domain now has an "Authenticate" button on it. This extra optional step means you adding two new DNS Records to your domain which tells the world that we are ok to send on your behalf from our mail servers and we highly recommend it.

If you wish to proceed, click the Authenticate button.

Step 7:

A drawer will open detailing how to add two new DNS records to your domain name. 

You should have access to your domain name's DNS records before proceeding. If you don't you may need to ask the person who registered your domain to do this bit for you.

  1. DKIM Record
    You need to add a CNAME record. Please see our guide on how to do this for each of the main domain registration control panels (123-reg, etc)
  2. SPF Record
    You need to add a TXT record. Please see our guide on how to do this for each of the main domain registration control panels (123-reg, etc)

    If you already have an SPF record in your domain setup (you can tell because the value will start with v=spf1) then you will need to update this record and not create a new one.

    If you need to update an existing SPF record, simply edit the value and insert "" after all of the other entries but BEFORE the last characters (usually ?all or ~all)

    So for example in this SPF record example you would insert our value here:

    v=spf1 include: ?all

    If you don't already have an SPF record, create a new one using the instructions on our Control Panel.

Step 8:

Now you have created both records click the "Continue" button back on our Control Panel.
Once the DNS changes reach us the drawer will close and your domain is ready to use.

Please note: It can take up to 48 hours for the domain changes to reach us, however ordinarily changes should reach us within 1 hour.

Step 9 (Paid Subscribers Only):

If you have a paid subscription you will notice the domain now says "SSL Pending". As part of our service to paid subscribers, we automatically generate SSL records for all domains added.

This process can take up to 1 hour so please wait until this SSL record changes to completed before sending.
