Spark
Spark is an email client for macOS that helps you manage multiple mail accounts, organize messages, and work through inboxes more efficiently.
What is Spark?
Spark is a macOS email app for people who want a more organized way to handle personal or work inboxes. It supports multiple email accounts in one place, including common providers such as Gmail, Outlook, iCloud, Yahoo, Exchange, and other IMAP services. The app focuses on everyday email workflows like reading, sending, searching, organizing, snoozing, and scheduling messages. Spark also includes tools for prioritizing important conversations, customizing notifications, and using a shared approach to email in team settings. For Mac users who spend a lot of time in email, it is designed to reduce inbox clutter and make routine communication easier to manage. Readdle publishes Spark as part of its productivity app lineup.

Safety overview
Status: Mostly safe
Spark is a legitimate email app, and access to your mail accounts, contacts, notifications, and internet connection is normal for its purpose. Because it handles email content and account connections, it can process sensitive personal and work information, so it is best used only with accounts you trust it to manage. Some features rely on account sync and cloud-connected services, which is typical for a modern cross-device mail app. If you use shared inbox or team features, be mindful about which conversations and attachments are visible to collaborators.
Recommendation: Keep Spark if you use it for personal or work email on your Mac. If you no longer use Spark, you can remove it, but expect to lose its local settings, cached message data, and any app-specific preferences on this Mac.
