How can I ensure that the email functionality in cPanel continues to work while hosting the website on Webflow with new A DNS records?

TL;DR
  • Update only the A and CNAME DNS records to point to Webflow while keeping all MX, mail-related A/CNAME, and TXT records unchanged.  
  • Confirm email routing is set to Local Mail Exchanger in cPanel and verify DNS changes with tools like MxToolbox to ensure website and email both function correctly.

To host your website on Webflow while keeping your email on cPanel, you need to update only the DNS records that affect web hosting and leave your MX records and mail-related records untouched.

1. Update Only A and CNAME Records for Webflow

  • Do not delete existing MX records in your cPanel or DNS.
  • Login to your domain registrar or wherever your DNS is managed.
  • Update the A records to point to Webflow’s hosting IPs:
  • (a) 75.2.70.75  
  • (b) 99.83.190.102
  • Use a CNAME record for the www subdomain:
  • Set the www CNAME to proxy-ssl.webflow.com.

2. Keep Existing MX and Email Records Intact

  • Your MX records route email via cPanel. If you delete or overwrite them, email will stop working.
  • Leave the following types of records untouched unless directed by your email provider:
  • MX records
  • TXT records for SPF, DKIM, or DMARC
  • A records or CNAMEs for mail subdomains (e.g., mail.yourdomain.com)

3. Confirm Domain Email Routing in cPanel

  • Login to cPanel.
  • Go to Email Routing under Email section.
  • Make sure your domain is set to Local Mail Exchanger (if cPanel is handling the email).

4. Verify Using DNS Lookup Tools

  • Use tools like MxToolboxDNSChecker, or your domain registrar’s DNS tool.
  • Verify that:
  • A and CNAME records point to Webflow.
  • MX records still point to your cPanel mail server (e.g., mail.example.com).
  • Any records for mail.example.com are unchanged and resolve correctly.

Summary

To host your site on Webflow and keep using cPanel email, only update the A and CNAME records for your website. Do not modify or delete your MX, mail A/CNAME, or TXT email records. This approach ensures your site goes live on Webflow while your email remains fully functional on cPanel.
