Cart Retention – Exit-intent popup & cart reminder mails

About the Extension

Bring carts back — with two channels in one plugin

Kommora Cart Retention keeps your customers buying when they are about to leave. An exit-intent popup catches them right in the shop. Then a three-stage mail reminder chain takes over — fully steered through the Shopware Flow Builder so you can adjust templates, timing and additional actions yourself.

Why this plugin?

• Measurable in €. The ROI dashboard shows you for the last 30 days exactly how many carts were recovered and how much revenue came back — broken down per reminder stage.
• Two channels, one plugin. Other plugins can do either popup or mail — here both are combined and cooperate without double-triggering.
• GDPR-compliant. Guest mail reminders only go out with explicit opt-in in the register form. Recovery links are HMAC-signed and unguessable.
• Flow-Builder native. The three reminder events are dispatched via the Shopware Flow Builder — you can replace templates, filter sales channels, attach Slack notifications or add custom actions.
