Hi @Prasanna, thanks for your post 
Here is how to connect a custom domain in Webflow: Connect a custom domain | Webflow University
Webflow does not offer email hosting yet, the MX records are managed at the DNS service provider where you host your domain, there you can enter your MX records and point those mx records at the server address for the service which provides your email.
For example if you are using Google Gmail, you would update your MX DNS records at your dns service provider to point to the MX records from Google found here: Activate Gmail for Google Workspace - Google Workspace Admin Help
If you are not sure how to update the MX records, contact to the support team at the service where you use to manage the domain name and I am sure they could help with that.
I hope this helps!
