Shopify email apps:
compare plans & features.

Find your email app. Keep the tradeoffs in view: what each app does, where it fits, and what you’ll pay.

Shopify’s allowance is included with an eligible paid store plan. Other rows show separate app subscriptions. SMS and usage beyond included limits can change the bill.

02 / Free allowances

“Free” has a ceiling.

Compare sends and audience limits together.
One email to 200 people counts as 200 sends.

Does the allowance cover it?

Shopify MessagingWithin 10,000

For stores on an eligible paid Shopify plan.

Klaviyo · Omnisend · Mailchimp Free300 over

800 sends exceeds each 500-send free allowance.

myuser.aiFree: 300 over

Free Capture allows 500 emails. Launch is $49/month and includes 10,000 emails, so it covers this email volume.

This compares email volume only. Audience limits, daily caps, features, and subscription costs still apply.

04 / Before you choose

A few things
worth clearing up.

Read the free-plan guide →
Is Shopify Messaging free?

Its first 10,000 monthly emails are included for stores on Basic, Grow, Advanced, or Plus. Your Shopify subscription is still paid, extra emails can cost more, and SMS has separate pricing. See Shopify’s pricing rules.

How much does myuser.ai cost?

Paid plans are Launch $49/month, Scale $129/month, Plus $299/month, and Max $699/month. There is also a capped Free Capture plan with 250 contacts, 500 emails, and 100 SMS segments per month. Eligible paid-plan trials last 30 days, with a 100-segment trial SMS allowance. See the plan breakdown.

Are contacts and email sends the same thing?

No. One campaign to 200 people is 200 sends; four such campaigns make 800. Billable contact definitions vary by app. Omnisend’s Free recipient limit is not a limit on uploaded contacts. Understand the billing units.

Is Shopify Email now called Shopify Messaging?

Yes. Shopify Messaging is the current name of the app previously called Shopify Email. See the Shopify Messaging profile for email and SMS details.

Which email app should I start with?

Choose the workflow first: campaigns inside Shopify, configurable segments and flows, or AI-managed follow-ups. Then calculate your email volume and compare the account price at that size. The largest free allowance does not tell you which workflow fits.
