Original Summary

Hello,<p>My name is Kostya Vasilyev and I was the original developer of an Android email app called Aqua Mail, sold to MobiSystems in 2019 at 3.5 organically grown users.<p>After that, I built a new email app called Sugar Mail, based on a cloud email sync platform. The project hasn&#x27;t been a success with end users, but I think the sync platform could be useful to someone so I&#x27;m looking to sell it and include the app too.<p>Mail sync runs in the cloud and supports IMAP and Exchange, both with push mail, and the latter with bi-directional calendar and contact sync. Both Office 365 and on-prem Exchange are supported. Running mail sync in the cloud allows the Android app to be very efficient in terms of battery use.<p>The Android app is just a JSON RPC client with some UI on top - so building an iOS or a desktop app would be pretty easy for the buyer.<p>There are several geo-distributed server nodes and the Android app uses the closest one. Adding nodes for capacity is easy.<p>The project is actively maintaned, with the Android app optimized for Android 17. The server is written in Go. I recently rewrote it in Rust, but decided to stay with Go in production for a variety of reasons (would be happy to explain in more detail).<p>Unit economics: a $10 VPS can handle 1000 users each averaging 2 email accounts.<p>A comparable platform is Nylas which charges $15&#x2F;month per 10 accounts and has no end-user app (they used to, but not anymore).<p>More details here: <a href="https:&#x2F;&#x2F;sugarmail.app&#x2F;for-sale-one-pager.html" rel="nofollow">https:&#x2F;&#x2F;sugarmail.app&#x2F;for-sale-one-pager.html</a><p>Happy to answer questions.
