Managing emails efficiently is a big challenge for professionals today. Whether you're an executive, team lead, or freelancer, keeping team inboxes organized can feel overwhelming. Superhuman and Spark are two popular tools designed to improve productivity. Superhuman is praised for its speed and sleek design, while Spark Mail stands out for its collaboration and shared inbox features. However, both have gaps in memory retention, workflow integration, unified inbox management, and contextual assistance.
This article will compare Superhuman and Spark, covering their strengths and weaknesses. We'll also introduce Tanka, an AI-powered email client add-on that enhances both apps with smarter features. By the end, you'll know which email tool suits you best and how Tanka can take your email management to the next level. If you want a smoother, more efficient email experience, combining Superhuman or Spark email agents with Tanka could be a game-changer.
Superhuman is built for speed and efficiency. It’s designed for professionals who want to get through their inbox quickly with minimal effort. Here’s what makes it stand out:
Blazing-fast email handling – Superhuman uses keyboard shortcuts and a sleek design to help you power through emails. You can archive, delete, or snooze messages with a single keystroke, saving valuable time.
Smart AI insights – It highlights important emails and manages follow-ups, so you never miss key messages. The “Split Inbox” feature automatically sorts emails into categories like Important, Unread, and Starred.
Boosts productivity – Features like reminders, split inboxes, and email tracking help you stay organized. You can set follow-up reminders or see when your email has been read, keeping you in control of your workflow.
Expensive subscription – At $30/month, Superhuman is one of the priciest email tools. This can be a dealbreaker for budget-conscious users, especially freelancers or small teams.
Limited browser compatibility – It only works with Gmail and Outlook, so if you use Yahoo, Apple Mail, or other providers, you're out of luck.
No memory of past conversations – Superhuman doesn’t remember context from old emails, making follow-ups harder. If you need to revisit a project email from months ago, you’ll have to manually search for past threads.
Smart replies: not available
Superhuman focuses on speed and inbox organization but does not offer AI-powered smart replies. Users must manually craft responses, even for common follow-ups.
Email integration: Gmail and Outlook only
Superhuman supports Gmail and Outlook, meaning it is limited to users with those email accounts. If you use a different email provider, Superhuman won’t be compatible.
If you love Superhuman’s speed but wish it could recall past conversations for a better email experience, Tanka’s AI memory feature can help you save time. It seamlessly integrates with Superhuman, offering smart replies and context-aware insights to streamline your workflow.
Spark Mail is built for teamwork. It’s perfect for teams that need to share inboxes, manage multiple accounts, and work together on email replies. Here’s what it offers:
Great for collaboration – Spark makes teamwork easy with shared inboxes and comment threads. You can invite team members to review and discuss an email draft before sending it.
Smart inbox sorting – It automatically highlights important emails so you can focus on what matters. Spark’s Smart Inbox organizes messages into categories like Personal, Notifications, and Newsletters, cutting down on clutter.
Scheduling and shared drafts – These tools boost efficiency, especially for teams managing high email volumes. You can schedule emails to send later or work on drafts together in real-time.
Email integration: Gmail, Outlook, iCloud, Yahoo, and others
Spark offers broader email support, integrating with Gmail, Outlook, iCloud, Yahoo, and other email providers. This ability makes it a versatile option for users with different email accounts.
Not ideal for solo users – Spark’s collaboration tools are great for teams but less helpful for individuals or freelancers. If you work alone, many features might feel unnecessary.
No memory of past emails – Like Superhuman, Spark doesn’t remember past conversations, making follow-ups harder. If you need to revisit a client request from weeks ago, you’ll have to search for the original thread manually.
Smart replies: basic, rule-based suggestions
Spark offers simple, pre-set quick replies (e.g., “Thanks!” or “Got it!”), but these are not context-aware. It does not generate personalized responses based on past conversations.
If you love Spark’s teamwork features but wish it could remember past conversations, Tanka’s AI-powered memory can help. It seamlessly integrates with Spark, offering smart replies and context-aware suggestions to keep your team on the same page.
Superhuman doesn’t offer context-based replies or remember past conversations. If you need to follow up, you'll have to manually review old threads and recall key details. While it excels at speed and organization, it doesn't assist with generating responses based on previous emails.
Example:
If a client asked for a project update and you received a follow-up a week later, you'd need to manually search through the past thread and craft your reply, maintaining a consistent tone yourself.
Spark Mail provides basic smart replies, but it doesn’t offer full context-based replies. It suggests canned responses like "Thanks!" or "Got it!", but it doesn't remember past conversations, requiring you to manually check old emails for context.
Example:
If a client asked about their order, Spark could suggest a generic reply like "I’ll check on that for you!" but won't recall the specific details of the order, making it hard to offer a tailored response.
While Superhuman call apps and Spark mail messaging apps are powerful on their own, they don’t address every pain point. That’s where Tanka comes in.
