How to Connect Google Domains to Mailgun

You just closed a massive deal. The client is thrilled. You spend days building out the perfect onboarding sequence in HighLevel. The copy is dialed in. The workflow logic is flawless. You hit publish and tell the client to watch their inbox.

Then, absolute silence. Not a single email actually goes out. You log into your dashboard and realize your entire email infrastructure is broken because your Google Domain was never authenticated. Your perfectly crafted emails are bouncing, the client is confused, and you look completely disorganized.

Email deliverability is the hidden engine of your agency. You cannot afford to skip the technical plumbing. Connecting Mailgun to your Google Domain ensures your emails actually hit the inbox. Let us lock down your sending infrastructure right now.

Part 1: Claim Your Mailgun Account

Ready to streamline this? Here is exactly how to do it in 60 seconds:

1. Go to Mailgun.com and sign up for a new account.
2. Check your email inbox immediately to verify your email address. Do not skip this step.

Part 2: Add Your Sending Domain

Time to tell Mailgun where your emails are coming from.

1. Log in to Mailgun and click on Sending, then select Add New Domain.
2. Decide if you are using your main domain or a subdomain. If you use your main domain, ensure it is not already used with Gsuite or another email provider.
3. Choose a subdomain like mg.companyname.com or replies.companyname.com to keep things safe and separated.
4. Select the US region for your setup. Do not select EU.
5. Click Add domain.

Part 3: Access Your Google DNS Records

Now we need to connect the pipes inside Google Domains.

1. Log in to domains.google.com and click into the specific domain you are setting up.
2. Click DNS on the left panel. We need to add 5 specific DNS records.

Part 4: Add Your TXT Records

Precision is everything here. Copy exactly what Mailgun provides.

1. Copy the first TXT record provided by Mailgun. It will look like v=spf1 include:mailgun.org ~all.
2. Select TXT from the Type dropdown in Google Domains.
3. Enter your Host name. If your subdomain is mg.companyname.com, the host name is simply mg. If you are using the main domain, the host name is @.
4. Paste the TXT record into the Data field. Do not click save yet.
5. Click Create new record to add the second TXT record.
6. For the second TXT record host name, copy everything from the beginning up until the subdomain part. Do not copy the main domain.

Part 5: Add Your MX Records

Let us finish the routing so your replies actually come back to you.

1. Click Create new record and select MX from the Type dropdown.
2. Set your Host name exactly like you did for the first TXT record. Use mg for a subdomain or @ for a main domain.
3. Paste 10 mxa.mailgun.org into the Data field.
4. Click +Add more to this record.
5. Paste 10 mxb.mailgun.org into the new field.

Locking down these records guarantees your agency can send bulk emails with a rock-solid foundation.
