Why your email is not working after DNS changes

If your email suddenly stops working after changing your DNS settings, the most common reason is that important MX records were overwritten or removed. This article explains why this happens and how to quickly restore your email setup.

What are DNS settings?

DNS stands for Domain Name System. It connects your domain to the correct services.

For example:

  • where your website is hosted
  • which provider handles your emails

For email, the most important entries are called MX records.

MX records are special entries in your domain settings. They define which provider receives and processes your emails. Without correct MX records, the internet does not know where your emails should be delivered.

Why your email stopped working

When you use a Jimdo Website Builder domain, your email is always managed by an external provider such as Google Workspace, Microsoft 365, or another email service.

This means:

  • Your email only works if the correct MX records are set
  • These records define where your emails are delivered
  • If they are changed or removed, your email will stop working

Common scenario:

  • You activate Email Forwarding or change settings
  • Existing MX records are overwritten or removed
  • Your email stops working immediately

Common causes

Your email may stop working after a DNS change due to:

  • MX records being overwritten when enabling email forwarding
  • Switching between different email options
  • Connecting your domain to another service
  • Changes made at an external domain provider
  • Incorrect manual MX record configuration

How to restore your email setup

The solution depends on how your email is configured. You can find all settings in your Jimdo dashboard under Email.

If it still does not work
