We're going to summarize that with a few of the different email apps that we think are best suited for Spark Mail-like experiences.

HEY! Email is one of the best email apps for personal productivity because it focuses on managing your calendar and email in a new and more effective way by shaking up how it is used and how you think about email.

The experience is a good rounder because whilst it does start you from scratch with the concept of managing a new domain, it does have some fundamental email systems and features that really go beyond even the lack of Spark Mail.

2. Superhuman

Why Superhuman should be considered?

Superhuman is a premium email application that commands nearly triple the price of options like Spark Mail, making it an option worth considering for those who spend a significant amount of time managing their emails.

In comparison to Spark Mail, Superhuman offers more premium features, including a faster way to access your emails and a greater emphasis on a command bar. This feature enables you to manage your inbox primarily through keyboard shortcuts, along with AI features that are being introduced.

Should you replace Spark Mail with Superhuman?

While these features are also present in Spark Mail, Superhuman packages them in a way that, in our opinion, is slightly more efficient.

However, the cost for Superhuman is $30 per month, which may be quite steep for many users. Therefore, we suggest considering Superhuman as an alternative to Spark Mail if you find yourself spending about 3 to 4 hours in your email daily.
