Usage charge explained

The app uses usage-based billing: you pay a flat monthly fee that includes a set number of emails, and only pay extra if you send more than your plan allows.

TL;DR

Your plan includes a fixed number of emails. Sending does not stop when you hit the limit. You can keep sending and pay proportionally for extra emails, up to 2x your plan limit. After that, sending pauses until you upgrade or top up.

How usage charge works

When you subscribe, Shopify shows an "App spending limit" screen. The spending limit is the maximum extra amount that can be charged per billing period above your base plan price.

You only pay for what you use. If you stay within your plan's email limit, you are charged only the base plan price. Extra charges only apply if you send beyond the included amount.

Plans and email pricing

Higher plans have a lower cost per extra email. If you regularly exceed your limit, upgrading is more cost-effective than paying per-email overages on a smaller plan.

Examples (Lite plan, $9.99/month)

When sending pauses, you can either upgrade your plan or increase your spending limit in the app to continue.

Understanding your usage dashboard

The usage screen in the app can look confusing at first. Here is what each number means:

Pro 100k	Your current plan. It includes 100,000 emails per billing period.
Dec 6 - Jan 5	Your current billing period. Counters reset at the start of each new period.
35,738 extra emails	Emails added to your limit after you exceeded 100,000. In this example, $1 was charged 214 times, each adding a batch of extra emails to your allowance.
135,640 emails sent	The actual number of emails delivered so far this billing period.
135,738 total allowed	Your current sending ceiling: 100,000 (plan) + 35,738 (unlocked via usage charges). You have 98 emails left before hitting this limit.
$214 spent	Total extra charges applied so far this period for emails beyond the plan's 100,000 base.
$599 spending limit	The maximum extra amount you have authorized. Once reached, sending pauses. You can raise this limit any time in the app.
98 emails remaining	Emails you can still send before the next usage charge is triggered. Sending beyond 135,738 will add another usage increment.
