Consider trying out the Order Status Tracker app as it presents an excellent option that provides numerous features and, importantly, offers value for your money. Here are a few compelling reasons to give the app a try:
1. 1100+ Carriers integrations
2. Last 60 days Order Synchronization
3. Unlimited Custom Statuses
4. Product Recommendations for Upsells
5. Email Notifications
6. Thank You Page Widget
Although 17Track is not too bad either. However, Order Status Tracker offers 1,000 extra orders for the same price ($49.00).
