If you feel like something's missing with Spark Mail, it might be time to switch things up.
The good news is there are plenty of options. This list includes seven of the best Spark Mail alternatives worth checking out.
Why might Spark Mail not work for you?
Founded by Readdle in 2015, Spark Mail has a decent following, but some customers find it can be slow and frequently has bugs.
Spark for Individuals is free, but a Premium account costs $59.99 annually or over $95 if you pay monthly. What's more, you must upgrade to Spark Premium to get rid of the "Sent with Spark" message on your emails, which can be a sticking point for many users.
Test-driving other email clients can help you find the best fit for your needs. We've done the hard work and compiled a list of Spark Mail alternatives.
What are the best Spark Mail alternatives?
1. Superhuman
Superhuman is the most productive email app ever made. With features like Instant Reply, Auto Summarize, Snippets, and Ask AI, you can fly through your inbox twice as fast, reply two days sooner, and save four hours every single week.
Instant Reply shows three pre-drafted replies under each conversation. You simply edit, then send — sometimes, you don't even have to edit. Meanwhile, Auto Summarize shows you a 1-line summary above every conversation. As new emails arrive, it updates instantly.
With Snippets, you can insert commonly used phrases, paragraphs, or whole emails with a simple keyboard shortcut. And with Ask AI, you can get rapid answers without having to remember senders, guess keywords, or comb through messages.
Superhuman AI helps you save time, get more done, and hit Inbox Zero faster than ever. It can:
- Turn an idea into an email
- Schedule at the speed of thought
- Polish your writing
- Summarize long email threads
- Search your inbox and calendar
Additionally, Superhuman now works wherever you do — so you can experience blazingly fast email from anywhere. Sign up for Superhuman today.
2. Microsoft Outlook
As part of the Microsoft 365 suite, Outlook has been a popular email service for some time. Although basic, this tried-and-true email platform has numerous features, from scheduling emails to creating a focused inbox, smart folders, and quick swipe controls.
Outlook is compatible with Windows and MacOS and can be accessed on mobile and desktop. This email client offers enterprise-grade security and supports Gmail, iCloud Mail, and Yahoo! Mail accounts — but not Apple Mail.
Follow-up reminders, a task manager, a note-taking application, contact management, and an integrated calendar make Outlook a hub of productivity. You can also create Do Not Disturb settings to maintain your focus on the task at hand — reaching the top of your inbox.
3. Gmail
Like Microsoft Outlook, Gmail is a popular free email client. This cloud-based, legacy email provider offers users standard encryption, lots of storage, and a modern interface with 30 different themes.
After signing up for a Gmail account, you'll unlock access to Google Cloud services like Calendar, Drive, Meet, and Chat. Toggling between different email inboxes is as simple as the push of a button — literally.
Some of the best Gmail add-ons allow you to maximize Gmail's features with the free version. However, you'll have to upgrade to Google Workspace for business connectivity.
4. Canary Mail
User experience and security features make Canary Mail a decent Spark Mail alternative. This popular email client is compatible with most email service providers and features numerous productivity tools.
SecureSend is Canary Mail's most notable feature, allowing users to implement the Pretty Good Privacy (PGP) protocol to encrypt the email's contents. Additional features include one-click unsubscribe, impersonation detection, a biometric app lock, and read receipts.
Canary Mail also integrates AI, which can help you summarize, write, and reply to emails. As a clean, modern inbox, it hits the mark. However, it also has a bit of a learning curve.
5. Mozilla Thunderbird
Mozilla's free and open-source email client, Thunderbird, provides users with a customizable interface, tabs for managing their calendar, contacts, and email, and extensions they can download to enhance their experience. Thunderbird is compatible with Windows and Apple operating systems.
Mozilla Thunderbird supports chat apps that can enable a team to collaborate effectively and efficiently. This email client also incorporates spam filters that learn which emails to divert as you flag them.
That said, Mozilla Thunderbird doesn't have a mobile app. While it supports POP and IMAP protocols, the open-source structure can leave users wanting more, whether it's features, customization, or hallmarks of other email services.
6. Edison Mail
An ad-free unified inbox can make all the difference in your email experience. Edison Mail is a solid choice because of its ability to compile multiple email accounts — up to 20 — in one place. That way, you can manage everything from a single dashboard.
Basic features such as undo send, snooze, contact management, sender blocking, read receipts, and customizable swipe options allow you to work through your inbox at your own pace. Although Edison Mail is free to download, it's not available for Windows users, and there's no mobile app you can download.
7. ProtonMail
If security is a priority for you, ProtonMail offers zero-access, end-to-end encryption via a zero-knowledge encryption standard. ProtonMail also doesn't track your IP address or require your name to create an account.
The home of self-destructing emails, ProtonMail offers a mobile app designed for the Mac/iOS App Store and Android devices. Users receive 500MB of storage, can send up to 150 emails daily, and have three folders for organization.
Limited integrations, minimal organizational tools, and no option to create a custom domain name rank ProtonMail lower on our list. Additionally, there are only eight color themes available, including dark mode.
The bottom line
Although there are several Spark Mail alternatives you can choose from, Superhuman allows you to fly through your inbox and save four hours per week, every single week.
