MX Records (Email)

What are MX records?

MX records (Mail Exchange records) tell the internet where to deliver email for your domain. If your email is you@yourcompany.com, the MX records determine which email server receives those messages.

This is the record people worry about most during a website migration — and rightly so. If MX records are misconfigured, email stops working.

How SiteGlowUp protects your email

We take email continuity seriously. Here's what happens:

1. Before migration — We scan your existing DNS records and detect all MX records, SPF records, DKIM records, and any other email-related configuration
2. During migration — We recreate every detected email record in your new DNS zone before the nameserver switch happens
3. After migration — We monitor your email records and alert you if anything looks wrong

Your email provider doesn't change. We're only moving the DNS records that point to it.

Common email providers and their MX records

Google Workspace / Gmail

• Uses MX records pointing to google.com mail servers


• Also has SPF and DKIM records for authentication

Microsoft 365 / Outlook

• Uses MX records pointing to outlook.com


• Includes SPF, DKIM, and often an autodiscover CNAME

Proton Mail

• Uses MX records pointing to protonmail.ch


• Has its own DKIM and SPF configuration

Other providers (Zoho, Fastmail, etc.)

• All follow the same pattern: MX records + authentication records

What if my email stops working?

In the rare event that email is disrupted:

1. Check your dashboard's DNS section — verify the MX records are present
2. If records are missing, contact support immediately
3. We can restore records from the backup taken during migration

We keep a backup of all your DNS records from before the migration. Nothing is lost.

Can I change email providers after migration?

Yes. Open the DNS section of your dashboard and click Add DNS Record. Choose MX as the record type, enter your new provider's mail server, and save — the record is live in Route53 seconds later. If you're replacing existing MX records (rather than adding a backup), reach out to support first so we can remove the old ones cleanly. See Adding DNS Records for details.
