We previously used Aftership, and can honestly say that Rush is leaps and bounds more superior than Aftership.- Using Aftership, they will add their branding in so many areas/properties that you own like in your site, in the order confirmation page, they even pester your customers with SMS and to download their app. Rush on the other hand is very clean and they don't require their branding on any of your assets. They integrate with other software like Klaviyo so well, giving you as a store owner so much more control over your messaging and branding with your customers. Rush Customer service (Gabriel and team) is excellent, one of the best we've experienced - they respond promptly, provide fixes and advice very promptly and overall always down to help and make their customers happy. The software is always expanding and growing. You'll see a few features in the pipeline under the settings tab which are really exciting like PayPal integration. Honestly, I can go on and on about how good this software is. There is a little but of a learning curve when you first run with Rush, but after you understand it in more detail you realize how essential and powerful it is. Courier mapping needs to be a little more fleshed out, however, there are hundreds (maybe thousands?) of small couriers so it's understandable that not everything is there. The major couriers like USPS, Royal Mail etc works well. Rush team, keep up the good work!
