Spark allows you to schedule emails to be sent at a later time, even if the app is not running on your device. Additionally, you can set follow-up reminders for emails you’ve sent, and if you haven’t received a response by the specified time, the email will be moved back into your inbox for follow-up.Snooze Emails
The Snooze feature lets you temporarily remove low-priority emails from your inbox and have them return at a specified time, helping you manage your emails more efficiently.Integrations with Third-Party Tools
Spark integrates with various third-party software and services, allowing you to quickly send emails to these services using swipe gestures. This integration streamlines your workflow by keeping all your tools connected within one app.Quick Replies
Quick Replies enable you to respond to emails with predefined or custom responses, complete with icons. This feature makes acknowledging or responding to emails quicker and less cumbersome.AI Writing Assistant ( AI)

- The AI drafts a response that matches the tone and context of your conversation.
- You can customize the response to fit your unique writing style using the “My Writing Style” feature.

Benefits of AI

Spark - Performance and Accuracy
Performance
Spark’s performance has received mixed reviews. On the positive side, Spark is generally easy to use and has a user-friendly interface, making it a great option for those looking for a simple and fast email client.
However, some users have reported performance issues, particularly since the update to Spark 3. Users have noted that the app can be slow and unreliable, with instances of crashing. This can be frustrating, especially for heavy email users.
Additionally, Spark’s mobile app is well-regarded for its speed and customization options, such as swipe gestures, which can significantly improve the email management experience.
Accuracy
In terms of accuracy, Spark has some areas that need improvement. For instance, the AI features, while helpful, do not always perform as expected. The AI-powered email assistant, Spark AI, can generate drafts and replies, but these often lack the personal touch and context that users might prefer. The AI does not always capture the full context of the email conversation, leading to somewhat basic and less personalized responses.
Another issue is with email classification. Spark groups notifications, newsletters, and 1:1 emails, but sometimes makes mistakes in these classifications. While these errors are easy to correct, they can still be inconvenient.
AI Features
Spark AI, the premium AI tool, aims to assist users in composing emails and rephrasing drafts. While it can save time and help with writer’s block, it does not always produce responses that sound like they were written by the user. This feature is more of a bonus rather than a primary reason to upgrade to the paid tier.
Email Storage and Backups
Spark does not backup emails locally; all emails are stored on the IMAP server. This means that users must be connected to the internet to access their emails, although Spark does cache emails for offline access over the past month.
Limitations and Areas for Improvement
- Performance Stability: The app’s performance can be inconsistent, with reports of slowness and crashing since the update to Spark 3.
- AI Context: The AI features could benefit from better context understanding to produce more personalized and accurate responses.
- Email Classification: Improving the accuracy of email classification would reduce the need for manual corrections.
- Customization: Allowing users to customize the groupings of notifications, newsletters, and 1:1 emails could enhance the user experience.
Conclusion
In summary, while Spark offers a user-friendly and fast email client with some useful AI features, it has areas that require improvement, particularly in terms of performance stability, AI context understanding, and email classification accuracy.
