Your domain name is the address people type to visit your website. Web hosting stores WordPress and the website files. Business email provides addresses such as hello@yourcompany.com. These are separate services even when one company bundles them into the same account.
Hostinger, Bluehost, and GoDaddy can place the domain and hosting in one account on eligible plans, which usually makes setup easier. Cloudways focuses on managed cloud hosting, so the domain normally remains with a registrar such as GoDaddy and is connected through DNS records.
If the domain and hosting are purchased together and connected during setup, manual DNS changes may not be necessary. If they are with different companies, point the domain to the hosting provider using the exact current values shown by that provider. Never remove email MX records just to connect the website.
