How it works

Checkout → consent → Mailster

Opt-in at checkout or form

WP Smart Consent adds a GDPR checkbox to any supported checkout or form. The customer explicitly agrees to marketing.

Consent is logged

Consent is recorded locally with a timestamp, giving you a full audit trail without relying on any third-party service.

Subscriber syncs to Mailster

In real time, WP Smart Consent calls the Mailster API and creates or updates the contact with name, email, and any mapped custom fields.

Your Mailster automations fire

Welcome sequences, post-purchase flows, or lead nurture campaigns in Mailster trigger exactly as if the subscriber came from a native form.
