Monthly Recurring Charges: Covers subscribes, unsubscribes, hello messages, surveys, and other administrative messages plus archives, search engines, refer-a-friend, URL and open tracking, if applicable. Also includes a number of message units based on your selected Service Type.

**Monthly Message Fees: The monthly message volume fee is actual message units sent over the message units that may be included with your selected Service Type. These prices are based on a message unit size of 40k (with the exception of the Starter Plan.). If you are planning to send messages larger than 40k these prices do not apply. Messages larger than 40k are calculated in increments of 1k, i.e., we do not round up to the next 40k level. You are only charged for the exact size of your messages (that are larger than your included message unit size, if applicable) that are processed for distribution to your mailing list. For example, if you sent a message that is 50k in size, you would be charged 1.25 message unit.

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.
