Zapier guide: use Gmail with a custom domain

Using Zapier together with Gmail and a custom email domain lets you keep a professional address while automating repetitive tasks in your inbox. This guide walks you through how to connect your domain to Gmail using Google Workspace and then layer automation on top to streamline your work.

What you need before you start with Zapier

Before you configure Gmail to work with a custom domain, make sure you have a few essentials in place so that everything connects smoothly with your future Zapier workflows.

• A domain name you control (for example, yourcompany.com)
• Access to your domain registrar or DNS provider
• A Google account or willingness to create a new one
• Basic comfort editing DNS records (MX, TXT, and CNAME)

The process is based on Google Workspace, which replaces standard Gmail for your custom domain. Once that is working, you can connect your account inside Zapier to automate email-related tasks.

Step 1: Choose Google Workspace for Gmail and Zapier

To use Gmail with your custom domain, you will sign up for Google Workspace instead of a personal Gmail account. This creates business email addresses like you@yourcompany.com and keeps them compatible with future Zapier automations.

1. Go to the Google Workspace signup page.
2. Enter your business name, size, and region.
3. Provide your current email so Google can contact you.
4. When prompted, indicate that you already have a domain name.
5. Enter the domain you want to use for Gmail.

Google Workspace will guide you through basic account setup, including creating your first administrator user. Keep those login details handy because you will later use this same account when you connect Gmail to Zapier.

Step 2: Verify your domain for Gmail and Zapier

To prove that you own your domain, you will add a verification record to your DNS. This step is required for Gmail to start handling email for your domain and is also necessary before you safely build any automations in Zapier.

1. Sign in to your Google Workspace admin setup wizard.
2. Choose the option to verify your domain.
3. Google will give you a TXT record that looks similar to google-site-verification=....
4. Open your domain registrar or DNS provider dashboard.
5. Add a new TXT record to the root of your domain using the exact value Google provides.
6. Save the DNS change and return to the Google Workspace setup wizard.
7. Click the button to verify your domain. This can take several minutes, depending on DNS propagation.

Once verification is complete, you are ready to point your domain’s email routing to Gmail and then connect the account to Zapier.

Step 3: Update MX records to route mail to Gmail

Mail exchange (MX) records tell the internet which service should receive email for your domain. To use Gmail, you will replace any existing MX records with the ones provided by Google. Having this correctly configured is important before you rely on any automated processing in Zapier.

1. In the Google Workspace setup wizard, open the section for MX records.
2. Copy the list of MX servers Google provides. They usually look like ASPMX.L.GOOGLE.COM and a few backup servers.
3. Go to your DNS provider and locate existing MX records.
4. Delete old MX records that do not belong to Google.
5. Add each Google MX record with the correct priority values.
6. Save the changes and return to the Google wizard to confirm.

MX changes may take time to propagate. During that period, email could be delivered to your old service or to Gmail. Once the change is stable, you can continue configuring your inbox and start planning which messages should later trigger actions inside Zapier.

Step 4: Secure your email before automating with Zapier

Good deliverability and security are essential if you plan to automate email tasks with Zapier. Google recommends setting up SPF, DKIM, and DMARC to authenticate messages sent from your domain.

Configure SPF records

Sender Policy Framework (SPF) specifies which mail servers may send email for your domain.

1. In your DNS settings, locate existing SPF TXT records.
2. If none exist, create a TXT record with a value similar to:
   v=spf1 include:_spf.google.com ~all
3. If you have other sending tools, merge them carefully into a single SPF record.

SPF alignment helps your emails stay out of spam, especially when you later trigger campaigns or follow-up messages via tools you integrate with Zapier.

Enable DKIM for stronger authentication

DomainKeys Identified Mail (DKIM) adds a cryptographic signature to each message.

1. Open the Google Workspace Admin console.
2. Navigate to the Gmail settings area.
3. Find the section for DKIM and generate a new key.
4. Google will provide a DNS TXT record with a unique selector name.
5. Add that TXT record to your DNS host and save.
6. Return to the admin console and click to start authentication.

After DKIM is active, messages from your custom Gmail domain will be easier for receiving servers to trust, which is important before scaling any automated communications you might orchestrate with Zapier.

Set a basic DMARC policy

DMARC builds on SPF and DKIM to define what should happen when messages fail authentication checks.

1. Create a TXT record at _dmarc.yourdomain.com.
2. Use a simple starting value such as:
   v=DMARC1; p=none; rua=mailto:you@yourdomain.com
3. Monitor reports and strengthen the policy over time.

A cautious DMARC policy lets you gather insight before applying stricter enforcement, which is ideal if you are testing new email-based workflows integrated through Zapier.

Step 5: Test Gmail with your custom domain

With DNS and authentication configured, you can test that Gmail is correctly sending and receiving messages for your domain.

• Log in to your new Google Workspace Gmail inbox.
• Send an email to a personal address on another provider.
• Reply from that personal address back to your new custom-domain inbox.
• Check headers in both directions to confirm SPF and DKIM pass.

Once everything looks correct, you have a fully functional professional email setup that is ready to connect with Zapier for advanced automation.

Step 6: Connect Gmail to Zapier

After your custom domain is live in Gmail, you can integrate it with Zapier to automate many common email workflows. The integration uses your Google account credentials but works seamlessly with the custom addresses you just created.

1. Sign in to your Zapier account or create a new one.
2. From the dashboard, click to create a new Zap.
3. Choose Gmail as the trigger app.
4. Click to connect a new Gmail account.
5. Authorize Zapier to access your Google Workspace account when prompted.
6. Select which Gmail address under your custom domain you want to use.

Once connected, you can create Zaps that react to incoming or outgoing email and send data to other tools in your stack.

Popular Zapier workflows for custom Gmail

• Create tasks in your project management tool when you receive emails from specific clients.
• Log new Gmail messages with certain labels into a spreadsheet or database.
• Send notifications to team chat when important emails arrive.
• Trigger follow-up sequences in your CRM when you star an email.

Each of these workflows begins with a Gmail trigger in Zapier and then uses actions in your other apps to move data automatically.
