How to Edit Your Namecheap DNS Records

Shown only logged in

If you have not yet first read about Setting up a Custom Domain, please read that first.

To send emails in Postaga from a custom domain, you will need to change the DNS records in your provider’s settings.

To do this, you will need to own a domain to send from (e.g. “”) and have access to the DNS settings in Namecheap.

This help doc specifically is meant to help you if your domain is registered with / hosted with Namecheap.

If your DNS is not with Namecheap, you can see here for more general help on editing DNS records.

To edit your DNS records, you will need to log into your Namecheap account.

Next, you will need to find the appropriate DNS records listed in your Postaga account to add in Namecheap.

You can get these records by going to your account APIs page and clicking the checkbox under custom domains. Here is a screenshot of an example below:

Using Namecheap as the example, you will need to:

Select Domain List from the left sidebar and click Manage next to your domain

namecheap select domain

Select the Advanced DNS tab at the top of the page:

namecheap advanced dns

This should get you to a screen where you can edit your DNS records.

In the Host Records section, click the Add New Record button 

namecheap add new record

Then, you will add additional DNS records from the Postaga API page. These will include:

  1. Two CNAME records
  2. Two MX records
  3. Two TXT records (one is the SPF record, one is the DKIM / domain key record)

In the Namecheap DNS system (BasicDNS, PremiumDNS, and FreeDNS), it is not needed to include the root domain name in the Host field.

So, instead of a host name record that says something like “” you would just enter “m.”

Also, you should not need to delete any existing DNS records that were already there.

Then, save the records you added.

Next, you can go to your Postaga API page and click “Recheck DNS” at the bottom of this page, and Postaga will verify the records.

Sometimes, it may take a few minutes for the records to update.

Once you see the checkmarks next to the MX records, your custom domain is confirmed.

Now, any campaigns that you send out will send from your custom domain.
