What is Mailspring?
Mailspring is a native desktop email client for macOS, Windows, and Linux that helps users manage personal and work email from one place. Developed by Ben Gotow, it supports multiple email accounts and offers a unified inbox so you can read and organize messages across providers without constantly switching apps. Common uses include handling IMAP and Office 365 mail, searching large mail archives, composing messages with signatures, and keeping inboxes organized with snooze and scheduling tools. The app also includes themes, layout options, notifications, and keyboard shortcuts that fit different work styles. Mailspring is especially useful for users who want a focused alternative to webmail while keeping their email available in a dedicated desktop workspace.

Safety overview
Status: Mostly safe
Mailspring is legitimate email software, but it handles sensitive account data by design, including message contents, contacts, and attachments you choose to sync. Network access, notifications, and local mailbox storage are normal for an email client. Some features may rely on Mailspring account services, so use the app only with accounts you trust it to manage and review its privacy settings before connecting important mailboxes.
Recommendation: Keep Mailspring if you actively use it for email. Remove it if you no longer need this mail client or prefer another one, but expect to lose its local cache, account setup, saved preferences, and any app-specific workflow features until you set them up elsewhere.
