letterboxlove review for Estimated Delivery Date ‑ ETA

May 18, 2026

We have been using this delivery ETA app since 2024, and overall our experience has been excellent. The app has helped us display clear and accurate delivery estimates to our customers, which has improved customer confidence and reduced delivery-related queries. Initially, I had some confusion regarding the lead days settings, cut-off timings, and weekend cut-off configurations, but after understanding the setup properly, everything started working perfectly as per our expectations. The app offers flexible configuration options, which makes it easy to customize delivery rules based on business requirements. We especially appreciate how smoothly the ETA rules work for different shipping methods and delivery schedules. The interface is user-friendly, and the app integrates well with our store. The support team is also very responsive and helpful. Whenever we had questions or needed assistance, they guided us properly and helped resolve our concerns quickly. Overall, it is a reliable app with useful features and good customer support.
