If your email just stopped working out of nowhere, most likely, you have recently updated your domain's nameservers.
Domain nameservers determine where the domain's DNS zone is managed from. For example, if you point your domain to Zyro via nameservers (dns1.zyro.com and dns2.zyro.com), your domain's DNS zone is also managed from Zyro.
All DNS records, including the ones that are responsible for email service, must be present in your domain's DNS zone at Zyro. For example:
Note: If you're not sure what exactly records are responsible for your email service, contact your email hosting provider 💡
Once you know what records are responsible for your email service, add them to your domain's DNS zone at Zyro:
1. In your Zyro dashboard, go to the Domains page.
2. Click Manage domain.
3. Scroll down a bit to find and expand the DNS records section.
4. Add or remove DNS records as described here.
