Pricing

You pay for contacts you actually email each month — not for every profile sitting in your account. One 30-day free trial, three plans, one fair-use rule. Billed through your Shopify invoice.

The plans

Plan	Price / month	Contacts emailed / month
Trial	$0 for 30 days	Growth-tier limits (15,000)
Starter	$79	up to 5,000
Growth	$149	up to 15,000
Scale	$349	up to 50,000

All plans include everything: all four flows, the full template library, MCP access for your AI, migration importers, and deliverability reporting. There are no feature gates — the tiers differ only in how many distinct contacts you can email per month.

Free forever, no trial required

The template library — browse and copy all 448 templates, use them anywhere.
MCP read tools — your AI can inspect templates, flows, and blueprints without an account.
Test-sends to your own inbox — judge the inbox placement yourself before paying anything.

How the trial works

Install the Charlie Shopify app. The 30-day trial starts — full features, Growth-tier limits (15,000 contacts emailed/month).
No charge during the trial. Billing runs through Shopify, so there is no separate card entry; you approve the plan on your Shopify invoice when you continue.
When the trial ends without a plan, sending pauses (API calls return 402 trial_expired). Nothing is deleted — contacts, flows, and history stay put, and the free tier above keeps working. Pick a plan to resume.

Fair use

Every plan allows up to 15 sends per contact per month. There are no per-send fees and no email metering below that line — a contact emailed ten times in a month still counts once against your plan. Calls beyond the cap return 429 fair_use_cap. The cap exists to protect deliverability for everyone (and, frankly, your unsubscribe rate).

Emailed vs. stored: the maths

Most email platforms price by stored contacts: every profile in the account counts toward the bill, including unsubscribed, suppressed, and long-dormant ones. Klaviyo, for example, has billed for every active profile — engaged or not — since February 2025.

A typical store's list is mostly quiet. Say you have 40,000 profiles but a sensible strategy emails the ~12,000 who have shown signs of life:

	Stored-contact pricing	Charlie
What you pay for	All 40,000 profiles	The 12,000 you email
Example monthly bill	≈ $600–720 (Klaviyo email plan, 40–50k profiles, list prices as of July 2026)	$149 (Growth)
Incentive it creates	Delete contacts to save money	Email only people worth emailing

The second incentive is also the deliverability-correct one — mailing your disengaged tail is how lists end up in the spam folder. Charlie's pricing and Charlie's sending mechanism point the same direction. Side-by-side price tables: vs Klaviyo, vs Mailchimp, vs Omnisend.

Practical questions

What counts as a "contact emailed"?

A distinct contact who received at least one email from you in the billing month. Flows and campaigns count the same; test-sends to your own inbox don't count at all.

What if I go over my tier one month?

Sending to new distinct contacts pauses at the tier limit until the month rolls over or you upgrade. Nothing is silently billed on top.

Annual plans? Hidden fees?

Monthly only for now, through Shopify's app billing. No setup fees, no per-send fees, no SMS credits to buy — Charlie is email only.

Start without deciding anything. Connect your AI and send yourself a free test email first — the trial can wait until you've seen where the mail lands.
