How to Set Up GMass for Better Email Deliverability

GMass: A Step-by-Step Guide

Email marketing is a powerful tool, but poor deliverability can hurt your results. Many users face challenges with GMass’s default tracking domains and email sending limits, leading to their emails landing in spam. In this guide, we’ll show you how to set up GMass properly using a custom SMTP service and a custom tracking domain to maximize deliverability and protect your brand.

Common Issues with GMass Deliverability

By default, GMass uses its own domain for tracking and bounce handling, such as amailroute.net. Unfortunately, this can cause your emails to be flagged as spam for the following reasons:

• Blacklist Issues: Many spam filters flag links from third-party tracking domains, particularly if they appear on URIBL blacklists.
• Inconsistent Branding: Using an unfamiliar tracking domain can reduce recipient trust and engagement.
• Strict Sending Limits on Free Gmail Accounts: Gmail limits sending to 500 emails per day, making it difficult to run larger campaigns.

The Solution: Custom SMTP + Custom Tracking Domain

To overcome these issues, we recommend:

1. Using a Custom SMTP Service – Centennial Arts provides reliable email hosting services that allow businesses to send emails with dedicated sending limits.
2. Setting Up a Custom Tracking Domain – This replaces GMass’s default tracking URL with your own domain, reducing spam flags and improving deliverability.

For more details on how a custom tracking domain improves deliverability, refer to GMass’s official blog post: GMass Custom Tracking Domain Guide.

Step 1: Setting Up Your Custom SMTP with GMass

To use your own email service for sending, you’ll need to configure GMass with SMTP credentials. If you use Centennial Arts Email Services, here’s how to set it up:

Configure GMass SMTP Settings

• SMTP Server: smtp.centennialarts.com
• Port: 587
• Username: Your business email (e.g., marketing@yourdomain.com)
• Password: Your email password
• Encryption: TLS

Verify Your Sending Address in Gmail

• Go to Gmail Settings > Click See All Settings > Accounts and Import
• Click Add another email address and enter your business email (e.g., marketing@yourdomain.com)
• Use the Centennial Arts SMTP settings above
• Verify the email by entering the confirmation code sent to your inbox
• Once added, set this email as the Default sending address
• Under When replying to a message, select Reply from the same address the message was sent to

✅ Now GMass will send emails using your business email and SMTP instead of Gmail’s servers, allowing for better control and higher sending limits.

Step 2: Understanding Your Sending Limits

Centennial Arts Email Sending Limits

• 40 emails per hour (maximum)
• 960 emails per day (24-hour rolling period)
• Better Reputation Control – Emails sent via Centennial Arts SMTP are less likely to be marked as spam compared to bulk sends through Gmail.

📌 Pro Tip: Use GMass’s built-in scheduling and throttling features to ensure you stay within the 40 emails per hour limit. Resource: Centennial Arts Email Sending Limits

Step 3: Setting Up a Custom Tracking Domain

A custom tracking domain ensures your emails do not contain links from blacklisted domains like amailroute.net. Instead, all tracking links will use your own domain.

How to Set Up a Custom Tracking Domain

1. Choose a Subdomain
   • Example: track.yourdomain.com
2. Update Your DNS Records
   • Log into your domain registrar (e.g., Centennial Arts/Enom)
   • Create a CNAME Record:
     • Host/Alias: track
     • Points To: x.gmtrack.net
     • TTL: Default value
   • Save the record and allow time for propagation
3. Verify in GMass
   • Go to track.yourdomain.com in your browser; it should display “hello.”
   • Log into GMass and navigate to Settings > Tracking Domain
   • Enter track.yourdomain.com and click Save Tracking Settings
   • This will assign track.yourdomain.com as your new tracking domain and automatically generate an SSL certificate, securing it over HTTPS.

✅ Now your tracking and bounce links will appear as track.yourdomain.com instead of GMass’s default domain, reducing spam flags and improving credibility.

Step 4: Creating and Sending a GMass Campaign

Once everything is set up, you can now create and send your GMass email campaign while ensuring you apply the correct settings.

Composing Your Email in Gmail

• Open Gmail and click Compose to create a new email.
• Write your email content as usual, adding any personalization or attachments.

Choosing the Correct Send Option

When sending your email, you will see two buttons:

• Send (Default Gmail sending)
• GMass (Uses GMass SMTP and tracking settings)

Always use the GMass button to ensure tracking and scheduling are applied correctly.

Adjusting Sending Speed in GMass

• Before sending, click on the GMass button dropdown > Schedule tab.
• Under Speed Settings, configure:
  • Speed: Send 864 emails/day
  • Pause: Set to 1-5 minutes between emails

📌 We recommend staying slightly under our 960 emails per day limit to provide a buffer for replies and inquiries from your campaign.

Confirm and Send

• Click the GMass button to start sending.
• Monitor progress through the GMass dashboard.

Step 5: Testing and Final Adjustments

Test Your Email Deliverability

• Send a test campaign to your own email and inspect the email headers
• Check the X-Spam-Status to ensure your score is low
• Click the tracking links and verify they use your custom tracking domain

Monitor Your Campaigns

• Check GMass’s campaign reports to track open rates, bounces, and engagement
• If needed, adjust your email content to improve deliverability

Final Thoughts

By following these steps, you can maximize email deliverability with GMass: ✅ Custom SMTP ensures emails come from your business domain ✅ Custom Tracking Domain removes spam-triggering third-party links ✅ Controlled Sending Limits prevent your account from being flagged
