Mailspring is free software and open-source utility for Mac operating systems. It is used to manage mailboxes on Mac computers. Mailspring provides a simple and clutter-free interface for Mac users.
Its main weakness is that it does not have an extensive range of features compared to some other similar products in the market. But there are some flaws which are more important than the minor shortcomings Mailspring has. For example, it lacks an efficient spam handling feature that could prove useful for organizations that have numerous accounts for managing incoming emails. The free version only allows you to manage five mailboxes for free. There is no option for unlimited email accounts. Another major weakness of this product is that it lacks any support for Mac databases such as the Mac Outlook database which is necessary for managing multiple email accounts on a single server.
Compared to other desktop email clients, Mailbird is a better choice for Mac users. Both Mailbird and Mailspring have the same basic features but Mailbird has several more helpful features that make it the better choice if you want a mail client with a clutter-free interface and powerful functionality. However, if you don't need all the extra features and just need one functional application, then go for the free version of Mailspring. Overall, Mailbird and Mailspring are both excellent email clients for Mac operating systems.
