Best Notion Mail Alternatives in 2026

Update: Notion Mail’s inbox is being retired. Notion is shutting down the standalone Notion Mail inbox on September 22, 2026, and folding email into the Notion suite through Gmail (Notion’s notice, Engadget). No email is lost: Notion Mail two-way synced with Gmail, so your sent and received mail already lives in your Gmail account. If your team is migrating, export any Notion Mail-only data (drafts, scheduled emails, snippets, and auto-label instructions) before September 21. Then decide where the inbox itself should live. The durable answer for a team is a neutral, cross-channel inbox, which is the case the rest of this guide makes. If you are ready to move, here is a step-by-step for migrating your team off Notion Mail.

Notion Mail brings email into the Notion workspace, so users can handle messages right alongside the notes, docs, and workflows they already keep there. But if you’re a knowledge worker juggling communication across email, chat, and project management tools, a Gmail-focused email solution usually isn’t enough. The right email management tool helps teams organize a unified inbox, cut down on manual follow-up, and pull actionable tasks out of every message, which is what tools like this+that are built to do.

Key Takeaways

• Multi-platform support matters: Notion Mail works only with Gmail. Alternatives like this+that cover Gmail, Outlook, Slack, and Microsoft Teams, so tasks come together across every channel
• Autonomous task execution separates this+that from standard extraction tools: this+that doesn’t stop at extracting tasks. It completes work across connected tools using the Model Context Protocol (MCP)
• AI feature depth varies significantly: 40% of professionals use smart reply features, and the tools themselves span everything from basic labeling to full autonomous workflows
• Integration architecture determines flexibility: MCP-compatible platforms can connect to any tool that exposes an MCP server, whereas closed ecosystems box in what your workflows can do

1. this+that: Autonomous Task Execution Across Every Channel

this+that goes past extraction to execution. Where other tools spot a task and hand it back to you to deal with, this+that reads the message, pulls the action item, and runs the multi-step workflows you set up across your connected tools.

Key Features:

• Multi-channel unification pulling tasks from Gmail, Outlook, Slack, and Microsoft Teams into a single unified inbox
• Autonomous task execution via workflows that complete work without manual intervention
• DoBox, a task manager that fills itself by continuously analyzing messages across all connected channels
• Model Context Protocol (MCP) integration architecture with 18 built-in servers plus any MCP-compatible API
• Natural language workflow creation requiring no technical configuration
• DoBox for Gmail Chrome extension embeds task extraction directly in your inbox
• Daily briefings surfacing priorities and action items from all communication sources

Teams reach for this+that when they need to turn messages into completed work across several communication channels at once, email, Slack, and Microsoft Teams included. It tends to show up in workflows where tasks get extracted, prioritized, and run through the multi-step automations you set up, connecting to MCP-compatible tools through its integration architecture.

The platform’s real strength is tackling the “manual tax” that wears knowledge workers down. Instead of just flagging the emails that need action, this+that runs the multi-step workflows you set up. A message with a client deadline can kick off automatic task creation, calendar blocking, and a team notification, once you have built the workflow for it.

If your team already spreads its communication across several platforms, the multi-channel approach kills the context switching that chews up productivity. You don’t have to bounce between Gmail, Slack, and Teams to round up your action items; this+that pulls everything into one workflow.

The MCP integration architecture is where it pulls ahead of closed ecosystems. Notion Mail only connects inside the Notion ecosystem, but this+that ships 18 built-in MCP servers and connects to any MCP-compatible API, including popular tools like Notion itself, HubSpot, and GitHub.

2. Superhuman

Superhuman is an email client built for professionals who want a faster, leaner inbox. You’ll mostly find it in the hands of executives, founders, and knowledge workers who deal with a lot of email and care about speed, keyboard-driven workflows, and inbox productivity.

Key Features

• Industry-leading email load speeds under 100 milliseconds: Email renders and responds almost instantly, so the lag that bogs down high-volume processing just isn’t there. Time-sensitive professionals can clear the inbox fast.
• Comprehensive keyboard shortcuts for power-user workflows: A deep set of command shortcuts lets you navigate, archive, label, and reply without ever touching the mouse. Once you’ve learned the commands, email processing speeds up a lot.
• Read receipts and email tracking functionality: Tracking is built in, so you can see when recipients open your emails and click your links. No external tracking tools or browser extensions needed.
• Split inbox and advanced triage capabilities: The inbox sorts itself into customizable categories, which lets you work through different kinds of messages in focused batches. That means less context switching and more attention on what matters.
• AI-powered email drafting assistance: Built-in AI helps you write replies, suggesting completions or generating full drafts from context. It’s handy for common email types and trims the time you’d spend on routine correspondence.

Superhuman is the pick for executives and heavy email users who put speed and efficiency first. It fits workflows where clearing the inbox fast, navigating by keyboard, and tracking email are what make or break the day.

It supports both Gmail and Outlook, which is broader coverage than Notion Mail’s Gmail-only setup. That said, the focus here is email speed, not multi-channel communication or autonomous task execution.

3. Shortwave

Shortwave is aimed at Gmail users who want strong AI capabilities. Its AI-powered search and summarization read for context and intent rather than keywords.

Key Features

• Semantic search that answers questions about email history: Search understands plain-language questions and what you mean by them, so you can ask something like “what did Sarah say about the budget?” instead of stringing together keywords. It surfaces emails by meaning, not exact text matches.
• AI-generated email summaries and thread digests: Long threads and individual messages get condensed automatically into key points and action items, so you can get the gist of a complicated discussion without reading every message in it.
• Smart inbox organization with AI-powered categorization: Machine learning sorts incoming email into the right categories based on content, sender patterns, and how you’ve behaved before. Less manual sorting, and priority messages still get noticed.
• Ghostwriter feature for AI-assisted email composition: The built-in AI writing assistant drafts your replies, either suggesting a full message or finishing a partial thought, which speeds up your response time on both routine and tricky emails.
• Action item extraction with deadline detection: Shortwave finds the tasks, requests, and commitments inside a thread and pulls out the deadlines attached to them, building a visible action item list without any manual tagging.
• Keyboard shortcuts for efficient navigation: Command-based shortcuts move you through emails, folders, and functions quickly, no mouse required. It’s a smooth workflow if you’re comfortable working from the keyboard.

Shortwave suits Gmail users who want AI-powered email management without a steep entry point. It works best where semantic search, automated summarization, and smart categorization cut down the time you’d otherwise spend processing and organizing email by hand.

It works only with Gmail, the same constraint Notion Mail has. If you’re on Microsoft 365 or need Outlook support, you’ll have to look elsewhere. But for Gmail-only teams, the AI features hold their own.

4. alfred_

alfred_ is all about turning emails into actionable tasks. Its whole pitch is email task capture: helping you spot the follow-ups, requests, and next steps buried in your messages so you can move that work into a more structured task workflow.

Key Features

• Advanced AI task extraction from email content: Machine learning reads through your email to find the action items, commitments, and requests tucked inside conversation threads, then builds explicit task lists out of those implicit mentions. You don’t have to flag them yourself.
• Action items with deadline detection: When the text mentions a time or a date, the system catches it and assigns a due date to the extracted task, so time-sensitive commitments get the right priority without you typing in dates.
• Split inbox for email triage and prioritization: Emails that need action get separated from the purely informational ones automatically, which lets you work through the task-heavy messages first and leave the lower-priority stuff for later.
• Support for Gmail and Outlook: Because it works across both, teams on Google Workspace and teams on Microsoft 365 can run the same task extraction workflows no matter which provider they’re on.
• AI email drafting assistance: Built-in composition support suggests responses and finishes partial drafts, cutting the time you spend on routine email and speeding up your reply cycle on common message types.
• Focused task management workflow: Extracted tasks land in a dedicated task view, complete with organization, prioritization, and completion tracking, giving you one central action item system that comes straight out of your email.

alfred_ works well for professionals drowning in task-containing emails who want to spend less time pulling out and recording action items by hand. It fits best where email is the main channel for coordinating projects and handing out tasks.

It supports both Gmail and Outlook, so it covers more ground than Notion Mail or Shortwave. The catch is that email stays its primary channel; it doesn’t reach into Slack or Teams.

If email is your team’s main channel and task extraction is the thing slowing everyone down, alfred_’s narrow focus pays off in measurable time savings.

5. Unboxd

Unboxd bills itself as an AI secretary that handles email management for you, swapping constant inbox-watching for a structured daily summary.

Key Features

• Daily briefing emails summarizing priorities and action items: A single morning digest pulls together your most important emails, the tasks Unboxd extracted, and the actions you need to take, so you start the day already knowing your priorities instead of reacting to the inbox.
• AI-powered email categorization and prioritization: Machine learning weighs each incoming message for urgency, importance, and whether it needs action, then sorts by relevance and pushes the high-priority stuff to the top, no manual triage involved.
• Support for Gmail, Outlook, and IMAP connections: Compatibility goes beyond the big platforms to nearly any email service that speaks standard IMAP, which means custom domains and niche providers are covered too.
• Action item extraction with due date detection: Unboxd scans your email for commitments, requests, and deadlines, and turns the natural-language mentions in the text into explicit tasks with due dates attached.
• AI email drafting and response suggestions: Built-in composition help offers response options and finishes drafts based on the email’s context, which speeds up your replies whether it’s a quick acknowledgment or something more involved.
• Unsubscribe management and inbox cleanup: Automated tools flag promotional and subscription email and let you unsubscribe in batches or clear out low-value messages, so the clutter thins out and you can focus on the mail that matters.

Unboxd is for professionals who want to spend less time in their inbox but still keep up with the messages that matter. It suits workflows where a daily digest stands in for constant inbox-watching and AI categorization brings priority messages forward on its own.

The daily briefing approach is what sets Unboxd apart from real-time email clients. Instead of nudging you to check your inbox all day, it gathers the relevant information into structured summaries that arrive at the times you choose.

Its IMAP support stretches compatibility past Gmail and Outlook to nearly any email provider, which is wide coverage compared with the other alternatives here. That’s a real plus if you’ve got a custom domain or a less common provider.

6. Carly AI

Carly AI comes at email productivity from a wider AI agent framework. Its workflows reach past email, tying your messages to task handling, follow-ups, and workflow automation across your other business tools.

Key Features

• AI agents capable of complex multi-step workflows: The agents run a whole sequence of actions across several tools and platforms, handling something like “extract client request from email, create project in task manager, schedule kickoff meeting, and notify team” without you stepping in at each stage.
• Pre-built integrations across categories: A large connection library covers project management, CRM, communication, file storage, and custom business tools, so you can automate workflows across very different software ecosystems without building your own API integrations.
• Support for Gmail, Outlook, Slack, and WhatsApp: Connecting across these channels brings task extraction and automation together over email, team messaging, and mobile messaging, catching action items wherever the conversation happens.
• Multi-channel communication management: One interface shows your messages, tasks, and notifications from every platform in a single view, so you’re not switching between separate email clients, messaging apps, and communication tools.
• Task automation across connected tools: A single automation rule can fire actions in any connected platform, covering scenarios like “when an email arrives from a client, update the CRM record, create a task in the project manager, and post a notification in the team Slack channel.”
• Team collaboration capabilities: Shared workflows, delegated tasks, and team-wide visibility let several people coordinate their automation, which keeps task handling consistent and stops two people from doing the same work when they share an inbox or team channel.

Carly AI fits teams that need broad integration capabilities and multi-step automation across a varied tool stack. It works best where tasks have to move automatically between platforms and coordinating the team means seeing across several communication channels.

Its integration breadth gives teams with a varied tool stack a lot of connectivity to work with. The WhatsApp support brings in a channel most email-focused alternatives skip.

The agent architecture can chain automation across multiple tools, though it leans on pre-built integrations rather than the open MCP approach that connects to any MCP-compatible tool. If your tools are already in Carly’s integration library, setup is simple.

When this+that is the Right Choice

Choose this+that when you need:

• Autonomous task completion: Extraction is only the start. Workflows actually carry out the work across your tools, automatically

• Broad integrations: Model Context Protocol connects to any MCP-compatible API through the integrations hub
• No-code automation: Workflows you create in plain language, no technical background needed

In email triage cases, where teams wade through piles of messages full of action items, this+that’s autonomous approach saves time that adds up day after day.
