Verification of the sender's email address is a prerequisite for sending an email campaign. When you have multiple senders on the same domain, this verification allows you to save your time by verifying your whole domain instead of verifying each sender's email address. The web application allows multiple verified domains based on your plan.
If you are having an active domain with the Namecheap, then follow the below steps to verify your domain registered with NameCheap in the web application.
Login to your the web application and navigate to Admin settings > Communication channels > Domain Verification > Add domain
Add your preferred domain in your web application
After entering the domain name and sender details, select “Create”. New DNS records will be created for the domain name you provided.
Note: You can send these DNS details to your IT team or to anyone who can add/modify DNS details for your domain by selecting "Send this to teammate"
Login to your Namecheap account
Navigate to Dashboard My Products and choose the domain you would like to verify in the web application and select Manage
In the new screen, check whether your name servers are being managed by Namecheap or Hosting provider.
If it is managed by your hosting provider then you will see “Custom DNS” option selected by default under “Nameservers”, In this case, you will have to login to your hosting account to add the web application's DNS records
If the nameservers are being managed by Namecheap then you will see “Namecheap Basic DNS” Option selected by default
Select “Advanced DNS” option to add the web application's records
a) Host Record
In the Host field, copy the Host record given in the web application and paste it without the domain name at the end. It is because Namecheap appends the domain name to the host names of CNAME records by default, hence It's not required to add the domain name again to the host record to avoid duplication.
The value is given in the web application: hxpbo._domainkey.yourdomain.com
The value you should paste in NameCheap Host field: hxpbo._domainkey
b) Value record
Copy & Paste the value record as it is given in the web application
Choose TTL as 5 minutes and select “Save all changes”
Similarly, paste all other records in Namecheap. Once you copy-paste all the records from the web application onto Namecheap, the records will look as depicted below in Namecheap
Now Click “Verify” domain in your web application to get all the records verified.
Always ensure the verification records are added to your DNS manager before you click “Verify” domain. You can see “Verified” status beside your domain name once records are verified
