DNS Setup for NameCheap
Log in to your Namecheap account. Choose Domain List from the Account drop-down list.
On the Domain List page, click on the Manage button next to your domain.
To create a DKIM record, go to the Advanced DNS tab and click ADD NEW RECORD under HOST RECORDS section.
Select CNAME Record from the Type drop-down menu.
Enter the Hostname we recommend into the Host field.
Note: You may only need to add the first part of the recommended hostname and not your full domain name to your DNS records as your provider may automatically add it.
Enter the Value that we advise for your CNAME record.
Select the desired TTL value from TTL drop-down menu.
Click on the SAVE ALL CHANGES button.
You can find the "Hostname" and "Value" under the Settings > Sender Domains section of your SMTP2GO Dashboard.
Repeat step 4 for each required CNAME record.
