This is okay for individuals who don’t mind that or someone who doesn’t develop their own mobile app projects for a tech company. Even then, be warned that you must give the precise information for the app to perform at all. ### 5/5 — Would Recommend *2023-10-09* I used the app to transfer my school mails it worked successfully, it helped a lot with the tutorials, the price is very good and reasonable for the work it does. I would recommend it. **Developer response:** Hi Pashteta, thank you so much for your kind review. Highly appreciated! 🙏 ### 5/5 — Best Email Migration Tool!!! *2022-09-03* This product surpassed all other email migration services I had tried prior. Great customer service support.

I used it to migrate gmail suite. ### 5/5 — Works like a charm *2021-09-23* So I had an issue with my previous hosting and I had to transfer to another one, and basically I was too lazy to transfer email using my computer since I was configuring everything from my phone. I found this app which had a negative comment but decided to give it a shot ! Honestly it works perfectly.. I did IMAP to IMAP migration and it transferred my emails… big thank you! ### 1/5 — Horrible *2021-06-23* What pain in the neck this app is. Does not work at all. Don’t download this junk. ### 5/5 — Parfait / Perfect ! *2021-04-30* Cette application est géniale. Les transferts sont vraiment pratiques pour gérer ses archives. L’application est simple et efficace. Le service support répond très vite et vous accompagne si vous avez un problème. J’ai pu transférer ma boîte de 15Go sans problème! This app is awesome.
