Building an email list can be risky
Customers buy, but the store has no way to invite them to a newsletter with explicit consent. Pre-checked boxes and sending data to external services are a GDPR risk and a loss of control over the list.
- ✗ No simple, GDPR-minded opt-in at checkout
- ✗ Pre-checked boxes break the explicit-consent requirement
- ✗ Subscriber data sent to external services
- ✗ No private, exportable subscriber list of your own

Frequently asked questions
Does it require WooCommerce?
Yes. WooCommerce must be installed and active, otherwise Subscribe shows a notice and does nothing else. The plugin declares Requires Plugins: woocommerce, so WordPress enforces the dependency for you.
Is the checkbox checked by default?
No. The checkbox is unchecked by default, so the customer has to actively tick it, which matches the GDPR requirement for explicit consent. A setting can pre-tick it, but it is off out of the box and may invalidate consent in the EU/UK.
Where are subscribers stored?
Each subscriber is a private "Subscriber" custom post type record under the WooCommerce menu, never shown publicly. The record holds the email, consent flag, opt-in source and a timestamp. You can download the whole list to a CSV file in one click.
Does it send the subscriber to Mailchimp or another service?
No. The free plugin has no integration with any external email platform and sends no addresses or order data off your site. Subscribers stay in your WordPress database, and what you do with the exported list is entirely up to you.
Does the checkbox show on the block checkout?
The checkbox renders on the classic (shortcode) WooCommerce checkout, after the terms and conditions. The plugin declares compatibility with the cart and checkout blocks so it does not trigger a warning, but the checkbox itself currently appears on the classic checkout.
Can the same email be stored twice?
No. Recording is idempotent: before adding a record the plugin checks whether the email already exists and skips duplicates. A returning customer therefore never creates a second entry on the list.
Does Subscribe send a welcome email?
Yes, but the welcome email is a feature of the paid Subscribe Pro add-on, not the free version. When enabled, Pro sends a plain-text welcome email on each new opt-in, with a configurable subject and body, and never sends it to the same subscriber twice.
How does Subscribe compare to MailPoet and Mailchimp for WooCommerce?
Subscribe adds a GDPR-safe newsletter opt-in checkbox at checkout with CSV export in the free version, then syncs subscribers to Mailchimp, Brevo and Klaviyo in the paid edition from €29/yr. MailPoet is a full sending platform priced by list size, while Mailchimp for WooCommerce is a free connector that only syncs to Mailchimp. Pricing as of June 2026.
