I have been using Sky Pilot for just over a year now. I have never had any issue with emails being delivered and customers having access to their downloads. It is very easy to use.
I recently updated my theme and forgot to reenter the code to give access to downloads through customer accounts. They helped me fix it and responded to quickly to emails.
Thanks Sky Pilot!

I gotta say, I am loving this app! We were using the free Digital Downloads and it was just not what we wanted - links were constantly breaking, zip files were a pain, and if someone wanted a refund there was no way to revoke their access since it was all done via e-mail. Almost half our customer service e-mails were just about links not working!

I am fairly new to the company and wanted to find a better solution and found SkyPilot - I was nervous because I am the LEAST techy person there is but it seemed pretty straight forward - and it has been! It's easy to install, easy to use, and does EXACTLY what we need it to do. It also looks so much more professional going through our site rather than an e-mail.

However, the real star of this entire product is Andrew - I must have asked him 1,000 questions before even purchasing to make sure this was right for us. He was so prompt and was able to explain everything perfectly. Once I installed I asked him a 1,000 more and he not only helped me via e-mail, but actually signed in and customized certain visual aspects the way I asked. Amazing. Hands down amazing.

We're still new to the app and just launched it a couple days ago but so far not a single bug, not a single problem. Wish all our apps were like this!!

Integrated will into my store. It has allowed our store to set up a variety of download combinations very easily. https://www.avoliner.com

Great seamless download gateway! Fantastic support from Jeff. Highly recommended instead of SendOwl or Shopify Digital Products. I love that it doesn't redirect my customers away from my domain to download the product.

We installed this app to deliver our digital products -- ebooks, echarts, eposters -- to customers of our music education shop (www.roedyblack.com). We were looking for a fast, seamless, trouble-free digital product delivery solution. We have been using Sky Pilot for a couple of months now, and our customers have downloaded thousands of files. Sky Pilot has more than lived up to our requirements and high expectations. The few times we have had questions, Sky Pilot support has always been prompt and thorough. Based on our experience, we strongly recommend this app.

Ok, maybe I was wrong. I thought the SkyPilot and ChargeRabbit are the same companies, but I got now (so quick as never before) an answer about that, referring to my review. They will do the support for ChargeRabbit too, so Andrew told me. That does not change anything to us that we could not use it for our business plan for selling distributions. Sky Pilot may be can helpful for downloads, but there is the problem with the big movie storage we need, so the monthly costs go up. So my proposal to Sky Pilot is to connect other of the many paywall sellers that are available now.

1st review:
We lost a couple of days to find out that it is not working for our business plan. We want to sell language learning movies as a subscription. That's it.
You have no Shopify cart, it will be bypassed directly to ChargeRabbit and the registration too.
Also, I get the feeling that SkyPilot and ChargeRabbit work together, there is the same support and it is the same delay. When you set up a question, it takes minimum 1 day. So we lost a lot of days, waiting for answers - most of them are not found in any description.
Why they have parted SkyPilot and ChargeRabbit? Maybe to take 2 times money.
So we change to a system that really delivers movies.

Brilliant app, will deliver streaming tutorial videos perfectly to our customers as www.DrAlexander.com

SkyPilot solves a huge problem for creators of content that wish to protect their Intellectual Property in a simple, secure, safe an effective way. Every feature I needed to accomplish this is in there. I can limit access to streaming only (no downloads) which eliminates the need for DRM protection of downloaded files - without DRM I feel files are just to easy for people to copy. I get flagged if too many IP Addresses are used to access content - further discouraging sharing. And just as important, Andrew was extremely helpful when I had some trouble, and went over and above with immediate tech support.

Andrew was amazing! he helped us get everything set up correctly :) Highly recommended app for digital downloads!

This app has the best customer support service I've ever come across. Prompt, straight forward and intelligent. Andrew fixed all of my issues for me on the spot, incredible. It delivers the product to my customers exactly the way I want it and it saves me so much time and money. I HIGHLY recommend it.
