Introduction

EZMailer is a powerful Chrome extension designed to help outbound marketing teams send unlimited personalized emails and mail merges directly from Gmail.

EZmailer integrates with Google Sheets to pull recipient data and automates the process of sending individual, anti-spam compliant emails at scale.

EZmailer is a third-party tool and is not affiliated with Google or Gmail.

  • Google Chrome browser (latest version)
  • A standard Gmail or Google Workspace account
  • Google Sheets with your recipient data
  • Stable internet connection

Installation

First-Time Setup

Campaign Engines

EZmailer provides multiple ways to reach your audience. Only one campaign can run per Gmail tab.

📻 Broadcast

Perfect for newsletters. Sends a one-time message to your entire list with personal tags.

⏳ Sequence

Automated drips. Set follow-up emails to go out after X days if no reply is received.

🎯 Transactional

Triggered emails. Use our API to send individual tracking-enabled messages.

Pro Multi-Account: Available for Elite users. Run multiple campaigns across different Google accounts simultaneously.
Ensure your email content complies with anti-spam laws (CAN-SPAM, GDPR). Always include an unsubscribe link.

Google Sheets Integration

Seamlessly connect your business data to your outreach workflow.

  • Create a sheet with columns like Email, First_Name, etc.
  • In EZmailer, select the sheet and tab.
  • Use {First_Name} in your email body to inject data.
  • EZmailer will automatically update the sheet with Sent_At and Status.

Personalization & Logic

Make every email feel hand-written. Advanced options include:

  • Conditional tags (If/Else)
  • Fallback values for missing data
  • Timezone-aware scheduling
  • Per-recipient attachment support

A campaign only starts if all required data columns are matched.

Deliverability Protocols

EZmailer is engineered for maximum inbox placement:

  • Random Sending Intervals – Variable delays between sends to mimic human behavior.
  • Broken Link Detection – Automatic check for dead links in your templates.
  • IP Warmup Logic – Gradually increases sending volume for new accounts.

Customizing Your Campaign

EZMailer offers a 5-tab settings panel for deep customization:

  • Recipients – Import CSV or Paste list, and map columns for personalization.
  • Schedule – Send immediately or schedule for a specific date/time. Set randomization delays (2-6s).
  • Tracking – Enable open tracking (pixel) and click tracking.
  • Follow-ups – Automate follow-up emails if a recipient hasn't replied after N days.
  • Options – Set test mode, override 'From Name', and set 'Reply-To' address.
