How to do Sustainable Email Marketing 

The conversations about climate continue to change. Environmental responsibility constantly gains momentum.  AND marketers are rethinking not just what they send, but how they send it.

Email marketing may seem invisible and paperless. It still leaves a digital footprint. Every message, server ping, and image file adds up. That’s why more companies are taking steps toward sustainable email marketing—and it’s not just good for the planet. It’s also good for business.

What Is Sustainable Email Marketing?

It’s an approach that reduces the environmental impact of email campaigns while improving relevance and user experience. Here’s how you can make your campaigns eco-friendlier (and effective):

1. Reduce Email Frequency

→More isn’t always better. Bombarding inboxes with daily emails not only leads to email fatigue and unsubscribes—it also increases your digital carbon footprint.

Solution: Send fewer, and smarter emails! Focus on behavior-triggered sends and personalized drip campaigns instead of broad blasts. Quality over quantity wins every time.

2. Optimize Content and File Sizes

→Heavy HTML, giant images, and long-winded copy make emails bloated and bandwidth heavy.

Solution: Trim the fat. Use clean code, compress images, and keep content sharp and to the point. Not only does this reduce energy use, but it also loads faster and performs better on mobile—where most people read their emails anyway.

3. Promote Eco-Friendly Practices

→Email is a powerful platform to inspire action.

Solution: Use your campaigns to promote sustainable products.  Share green tips or highlight your company’s own environmental initiatives. Conscious consumers love to support brands that support their values.

How Our Message Pricing Works

  1. Included Monthly Messages
    Each plan comes with a certain number of included messages at a standard size (up to 40K per email).
  2. Overage Rate
    After you’ve sent all your included messages, each additional 1,000 emails costs $0.90.
  3. What If an Email Is Larger Than 40K?
    • We measure every extra 1K of data beyond 40K as an extra fraction of a message.
    • Example: A 50K email counts as 1.25 messages (because 50K is 1.25 × 40K).
    • This prevents rounding up to a full extra 40K block when you only need 10K more.
  4. Covered by Your Monthly Fee
    • All administrative and automated list messages (welcome emails, unsubscribe confirmations, surveys, etc.)
    • Access to features like archives, refer-a-friend, click/open tracking, feedback loops, and more.
