LC Email Dedicated Domain Setup — GoDaddy
A step-by-step guide to adding and verifying your dedicated sending domain using GoDaddy DNS.
What You'll Learn

This article walks you through connecting a dedicated sending domain to LC Email using GoDaddy as your DNS provider. You will add 5 DNS records in total: 2 TXT records, 2 MX records, and 1 CNAME record.

Unlike some DNS providers, GoDaddy requires you to save each record individually. Follow the steps in order and click Save after each record before adding the next.

1

Add Your Domain in Email Services

Step 1
Navigate to Dedicated Domain settings

In your sub-account, go to Settings → Email Services → Dedicated Domain and click + Add Domain.

Navigating to Settings > Email Services > Dedicated Domain > + Add Domain
Navigating to Settings → Email Services → Dedicated Domain → + Add Domain
Step 2
Choose your domain type

If your domain is companyname.com, you can register either the root domain or a subdomain as your dedicated sending domain.

Main domain (companyname.com) — must not already be in use with Google Workspace or another email provider.

Subdomain — enter any prefix before your root domain, for example replies.companyname.com or support.companyname.com.

Note

If you use Google Workspace or another email provider on your root domain, adding the root domain here will conflict with your existing MX records. Use a subdomain instead. See Can I use the same domain for Mailgun and Google Apps?

Step 3
Click Add & Verify

After entering your domain name, click Add & Verify. The next screen will display the 5 DNS records you need to add. Keep this tab open — you will copy values from it in the steps below.

  • Setting up root domain companyname.com → enter @
GoDaddy Host field — enter subdomain prefix only

Everyone's 2nd TXT record hostname and value is unique to their domain. Copy both values directly from your platform's DNS records screen — do not use values from screenshots in this article.

Click Add in the GoDaddy DNS editor to create a new record.

Add the 1st MX Record (mxa.mailgun.org)

Google Workspace Users

If you use Google Workspace to send and receive mail on your root domain, adding MX records to the root domain will break your existing email. Use a subdomain for LC Email instead. See Can I use the same domain for Mailgun and Google Apps?

Click Add in the GoDaddy DNS editor to create a new record.

Switch back to the platform tab and click Verify Domain on the Email Services screen.

Verify Domain button in Email Services
Some records still not green?

DNS propagation can take a few minutes. Click Verify Domain again after waiting a moment. If records remain unverified after 10+ minutes, go back to GoDaddy and confirm each record's Type, Host, and value are correct.

You're All Set

Once all records show a green checkmark, your dedicated sending domain is active. Next, confirm your SSL Certificate for Dedicated Sending Domain (LC Email) is properly set up.

Then send a test email to confirm everything is working. Learn how to send a test email in the Conversation.

Frequently Asked Questions

Q: Why do I need to save after each record in GoDaddy?
GoDaddy's DNS editor saves records one at a time. Unlike some providers that let you queue multiple records and save at once, GoDaddy requires each record to be individually confirmed. Follow the steps in order and click Save after each one.
Q: Can I use my root domain if I already use it with Google Workspace?
No. Adding MX records to a root domain that is already in use with Google Workspace will conflict with your existing email setup. Use a subdomain (e.g. replies.companyname.com) for LC Email instead.
Q: Why do I add two separate MX records instead of one?
The two MX records (mxa.mailgun.org and mxb.mailgun.org) provide redundancy — if one mail server is temporarily unavailable, the other can receive messages. Both should be added with Priority 10. GoDaddy requires each MX record to be added and saved separately.
Q: Why is the 2nd TXT record hostname different from what I see in examples?
The 2nd TXT record is a DKIM key generated uniquely for your domain. Its hostname and long value are always different per account. Always copy both from your own DNS records screen — never use values shown in screenshots in this article.
Q: How long does DNS propagation take in GoDaddy?
GoDaddy DNS changes typically propagate within a few minutes to an hour. If records are still not verifying after 10 minutes, wait a bit longer before troubleshooting. Full propagation can take up to 48 hours in rare cases.
Q: What is the difference between a dedicated and a shared sending domain?
A shared domain is used by multiple accounts, meaning your sender reputation is pooled with others. A dedicated domain is exclusive to your account, giving you full control over your deliverability reputation as it builds over time.
Q: My domain shows as verified but emails are not delivering — what should I check?
First, send a test email from the Conversations area to confirm basic sending is working. Then check that the SSL Certificate for your Dedicated Sending Domain is active. If issues persist, review each of your 5 GoDaddy DNS records for typos in the Host or Points To fields.
Q: Can I set up multiple dedicated domains for different sub-accounts?
Yes. Each sub-account can have its own dedicated sending domain. Each domain requires its own complete set of 5 DNS records to be added and verified separately in GoDaddy.
