Senior E-commerce Retention & Email Marketing Specialist Design Mid-Market (51-1000 emp.) 5/17/2026 "Streamlined Email Automation with Excellent GDPR Compliance" 4.5/5 What do you like best about Rejoiner? At Remerge GmbH, we rely heavily on Rejoiner to execute full-cycle email retention and customer re-engagement strategies for German e-commerce brands. It works exceptionally well for setting up automated abandoned cart reminder flows, winning back dormant customers, and building complete post-purchase email journeys. I really appreciate its user-friendly drag-and-drop workflow builder, which lets our marketing team design highly personalized email sequences easily without needing support from the IT department. We can segment audiences precisely based on actual shopping habits, spending levels and browsing activity to deliver targeted messages. The most valuable advantage for our German market business is its robust built-in GDPR compliance framework. It fully satisfies local strict data privacy rules, making all our email marketing campaigns legally safe and standardized. Additionally, connecting Rejoiner with popular platforms like Shopify and Magento is quick and hassle-free, allowing us to launch formal marketing campaigns in a short time. Review collected by and hosted on G2.com. What do you dislike about Rejoiner? The native reporting system is its most noticeable weakness. Our team manages marketing services for multiple independent D2C stores across Germany, but the current dashboards do not support direct cross-brand data comparison. We cannot instantly view unified data such as cart recovery ratios, customer conversion performance and overall campaign ROI. We have to manually export raw data regularly and organize everything in custom spreadsheets for in-depth analysis, which creates extra repetitive workload every week. It would be far more practical if Rejoiner added ready-made multi-client overview reports and customizable regional performance dashboards. Review collected by and hosted on G2.com. What problems is Rejoiner solving and how is that benefiting you? Rejoiner effectively eliminates all the tedious manual work involved in traditional email marketing operations. All customer follow-up emails can be automatically triggered based on real-time user behaviors, including cart abandonment and long-term account inactivity. This ensures we never miss any potential sales opportunities even during holiday shopping peaks. It significantly reduces our team’s daily operational pressure, stabilizes customer reactivation efficiency, and consistently helps our local German clients recover substantial lost sales revenue and improve overall customer loyalty.
