If you want to use Namecheap email forwarder then you must use Namecheap BasicDNS. Namecheap email forward will not work if you use another nameserver.
- First things first: Make sure you have followed the first steps in Connect Your Custom Address and you have your ThriveDesk Inbox Address ready.
- From your Namecheap dashboard, click on Domain List in the left sidebar menu.
- Click on the domain you'd like to modify and click on the Manage button.
- Go to Advanced DNS menu select Email forwarding from the dropdown of Mail Settings.
- Scroll down to the Redirect Email section, and click on the Add Forwarder button.
- Enter your alias (for example, for help@acme.com, you'd type in help) into the Alias field, and paste the ThriveDesk email address into the Forward To field. Click the green checkmark to save your changes.
