I installed Mailspring and I liked it. BUT, it lacks of some necessary facilities to make our life easier. For instance, links and shortcut to Contacts. Is it so difficult to include such piece of code?

I love the features but not the price. The swipe functions are smooth; the snooze later works great.
NEW, though, is a limit of opening only 5 emails per week? Don't update if you have an older version. I cannot afford $8 a month, so I will have to switch programs.
There are a lot of really neat things about this mail client. I was briefly very excited by it. But it's a dead product with deal-breaking bugs.
It's a poorly optimized web-app (Electron) that takes up a lot of disk space and burns through battery on a laptop. Often needs to be closed and re-opened to restore responsiveness. Typing long messages in particular make is churn down to several seconds between visual updates.
It doesn't integrate with any address book of any kind.
The composer is very basic - think boilerplate WYSIWYG. No image resizing. No tables. I could go on.
It's a paid product making a sustainable amount of revenue (unless there are really only a handful of subscribers), showing that the maintainer is negligent or unskilled to the extent that it's unreasonable to think that these problems will be fixed within even the next half decade.

Speaking as the new Volunteer Community Manager, the project is NOT abandoned.
Development temporarily halted due to 2020 being what it was, but it has resumed. 1.8.0 just released this week, and another release is planned for the next couple of weeks.
Also, the revenue is not as high as you might think. The costs of providing some of the premium features is substantial. The maintainer is far from negligent or unskilled, but he also has limited time, as he has a full time job besides this. Open source contributions enable Mailspring to move forward.
Well, we're 2 years into my estimated "next half decade" and people are still experiencing these issues. It doesn't give me any confidence to hear that the maintainer is spending so much on "some of the premium features" while basic fundamental functionality and stability languishes.
This issue is still apparent in July 2021. So many of their users are now switching back to the email client they came from. The software is riddled with bugs making it unusable, and many of us have paid for it. If open source contributions are needed to move this software forward then the core developer should be focusing on this instead of just hoping that people will come forward. Many of it's users, including the agency I am from, have no knowledge of working with Electron - surely they must have a community somewhere to try and bring developers into this project...(?)

Mailspring is a very modern, attractive, responsive cross-platform open-source (private) email app with a lot of great features. Unfortunately there are still several key features missing vs. its more established alternatives, such as independent contact and calendar sync by way of CardDav/CalDav, etc. Very promising app, but still lagging behind in development of key features.
It's not native, the framework is too heavy on resources even on a high level machine. Interface is good, but doesn't mean much when it's not usable.
It is stated as "Email Client", but it is not true. This is a cloud service. It does not work when the mail server is running, but without access to their cloud. I got the message "Could not reach id.getmailspring..." during installation. Unable to complete installation as well as offline installation.
Windows version requires .Net 4.5+.
