Key Takeaways
- Already use ChatGPT or Claude? Start with their Gmail or Microsoft connections for everyday email tasks; add Clean Email for bulk cleanup across providers.
- Want a free starting point? Try Claude’s Gmail connector, eligible built-in Gemini or Copilot features, or MailMaestro’s limited free plan.
- Want triage handled for you? Fyxer sorts incoming mail; Cora turns it into scheduled Briefs.
- Check permissions before connecting: automatic sorting, sending, and deletion are different levels of access.
- Clean Email is the cleaning tool for your AI assistant: it finds clutter and clears what you approve.
Three Ways to Get AI Help With Email
- Built-in AI: Gemini in Gmail and Copilot in Outlook put summaries, writing assistance, and supported actions inside your existing email app.
- Dedicated tools: Fyxer and Cora work alongside your inbox. An AI email client such as Superhuman Mail, Spark, or Canary replaces the interface you use to read and send messages.
- Connected assistants: A ChatGPT email assistant or Claude email assistant lets you ask questions about your mailbox in a familiar chat. Specialized tools such as Clean Email add bulk cleaning and support for providers beyond Gmail and Microsoft.
The guide to AI email management explains how to choose an approach. An assistant generally responds when asked; an agent can also follow instructions in the background. Check what each product is allowed to do automatically.
For more options focused on sorting, consider Shortwave, an AI-focused Gmail client.
Inbox Zero offers open-source email automation, with hosted plans from $20/user/month on monthly billing.

The 10 Best AI Email Assistants
1. Clean Email With ChatGPT, Claude, or Codex
Best for: Bulk cleanup through the AI assistant you already use.
Connect Clean Email to ChatGPT, Claude, or Codex to manage inbox cleanup in plain language. Ask your assistant to find old newsletters, clear unwanted messages, or suggest where to start. It uses Clean Email to find relevant messages and explain your options. Once you approve the cleanup, Clean Email carries it out.
You can delete messages in bulk, unsubscribe from multiple senders with Unsubscriber, and create Auto Clean rules to keep future clutter under control. Clean Email supports Gmail, Outlook, Hotmail, Yahoo, iCloud, AOL, and other mail providers. You can manage each connected mailbox and apply the same cleanup rule across accounts.
Clean Email works alongside your preferred email app. You can keep your everyday email routine while using your AI assistant to handle bulk cleanup and create or change cleaning rules.
Price: The connection is available to all Clean Email users, including the free trial, which lets you clean up to 1,000 emails. Paid plans start at $9.99/month for one account.
2. ChatGPT
Best for: Finding answers and drafting in a familiar conversation.
Connect Gmail or Outlook and ask, “Which messages need a reply today?” or “Summarize the decisions in this thread.” ChatGPT can then help turn the results into a response.
With Gmail or Outlook connected, ChatGPT can draft and send email from the same conversation on the web for Plus, Pro, Business, and Enterprise users. You review the draft and choose to send it. Additional Outlook actions depend on your account permissions and workplace settings.
Broad searches may miss messages, so narrow the date range or ask follow-up questions. These connections suit everyday email tasks; Clean Email adds tools designed for bulk deletion and unsubscribing across providers.
Price: Free for general drafting; Plus is $20/month. Connected features depend on plan, region, interface, and workspace controls.
3. Claude
Best for: Email questions and drafts, including on the Free plan.
Claude’s Google Workspace connectors are available on every plan, including Free. With Gmail connected, Claude can search and read messages, draft replies, manage labels, and send, reply to, or forward email. Sending actions ask for approval by default. It can access Gmail attachment details, but not their contents.
The Microsoft 365 connector requires a work account; personal Outlook.com and Hotmail accounts are unsupported. Sending and organizing also require administrator consent and enabled write tools.
Claude lets you manage tool permissions, including requiring approval or disabling tools. Automatic actions depend on the tool and your organization’s policies. Connect Clean Email when you need bulk unsubscribing, a large cleanup, or support for providers such as Yahoo and iCloud.
Price: Gmail connectivity is included on Claude Free, subject to usage limits; Microsoft 365 requires an eligible work account and setup.
4. Gemini in Gmail and Copilot in Outlook
Best for: AI inside the email app you already use.
Gemini is an AI email assistant Gmail users can access inside their inbox for summaries, writing help, and email questions. AI Inbox began expanding to eligible paid Workspace accounts in October 2026, initially in US English in the US. It surfaces suggested to-dos and important updates; rollout timing varies by edition. Gmail Live also adds voice questions on eligible plans. Organizing actions may not be available in every account.
Copilot is an AI email assistant Outlook users can access in their email app to summarize threads and draft replies. Supported chat actions include deleting, moving, and categorizing mail, plus managing inbox rules. Microsoft asks for confirmation before actions affecting more than five emails and before creating or changing inbox rules. Actions affecting five or fewer emails may run without a separate prompt.
Price: Some Gemini and Copilot features are included with eligible subscriptions. Microsoft 365 Copilot Business has a standard price of $21/user/month with annual billing, before promotions, and requires a qualifying Microsoft 365 plan.
💡 Tip: If you use Outlook, see the Outlook AI guide to compare built-in Copilot features with other tools that work with your mailbox.
5. Fyxer
Best for: Automatic triage and prepared replies in Gmail or Outlook.
Fyxer suits people who want incoming email sorted before they open their inbox. It labels messages by purpose, including To respond, FYI, and Marketing, and prepares replies in your writing style. It works with Gmail and Outlook and also offers meeting notes and follow-up support.
Sorting runs automatically after setup, including routing selected categories out of your inbox. Drafts stay available for you to review and send; Fyxer does not send them automatically.
Automatic labeling and personalized reply drafts require a paid plan. The Free plan offers limited credits for other features, so it is not a free substitute for the paid inbox workflow.
Price: Free with limited features. Pro costs $37/person/month with annual billing or $49 monthly; Team costs $64/person/month with annual billing.
6. Cora
Best for: Gmail users who prefer a scheduled briefing to constant inbox checks.
Cora turns incoming Gmail messages into scheduled summaries called Briefs. Important messages stay in your inbox; less urgent mail is categorized and archived for your Brief. Its standard screening workflow also prepares drafts for you to review and send.
Cora sorts and archives automatically rather than requesting approval for each message. Review its categories and Brief schedule so you know which messages remain visible and when summaries arrive.
Cora supports personal Gmail and Google Workspace accounts and works alongside your existing email app. Choose it for ongoing triage and briefings; use a dedicated cleanup tool when your main goal is bulk unsubscribing.
Price: Professional is $20/month billed annually at $240, with a free trial.
7. Superhuman Mail
Best for: Professionals who want a faster email client with integrated AI.
Superhuman Mail combines keyboard-driven email handling with Auto Labels, summaries, writing help, and, on higher plans, Auto Drafts and Ask AI. The Ask AI feature can also work with attachments and images.
Grammarly became the Superhuman company in October 2025. The email client is called Superhuman Mail.
Superhuman Mail supports Gmail and Outlook and provides its own email interface. Auto Labels and configured Auto Archive settings can organize messages automatically. AI drafts are prepared for review before you send them.
Price: Starter costs $25/member/month with annual billing. Business costs $33/member/month with annual billing and includes Ask AI and Auto Drafts.
8. MailMaestro
Best for: Drafting and summaries inside Outlook or Gmail.
MailMaestro works inside Outlook or Gmail to help you write replies, adjust tone, and summarize long conversations. Flowrite is now part of MailMaestro, so readers comparing the two should treat them as one product.
Auto labels and Auto drafts are also available in Gmail. Once enabled, labels and folder routing can organize incoming mail automatically. Prepared replies remain drafts for you to review, edit, and send.
Choose MailMaestro if you want help turning a long conversation into a clear reply without adopting a different email client. Its writing and automation features are useful for different jobs, so enable only the ones you need.
Price: The Free plan includes three writing requests a week. Pro starts at $12/seat/month with annual billing. MaestroDuo combines email and meeting tools for $25/seat/month with annual billing.
9. Spark Mail +AI
Best for: An AI email app for multiple accounts, with optional automation.
Spark is a full email app with a unified inbox and support for several providers. Its free tier covers core email handling; paid +AI features add drafting, proofreading, translation, summaries, and an AI Assistant.
Spark +AI is off by default. Pro adds Auto-Drafts and Autopilot: you can configure rules to leave a draft for review or to reply or forward immediately. Choose draft-only rules if you want to approve every outgoing message. Auto-Drafts is rolling out in phases, so it may not be available in your account yet.
Choose Spark if you also want a different email interface. If you want to keep Gmail or Outlook, a built-in assistant or add-in may be easier.
Price: Free core email app. Plus costs $10/user/month and Pro costs $20/user/month on monthly billing; annual plans cost less.
💡 Tip: Before switching email apps, read the Spark AI review for a closer look at its AI features and everyday email workflow.
10. Canary Mail
Best for: Lower-cost AI writing and summaries across providers.
Canary Mail combines a unified inbox with an AI Copilot for composing, summarizing, and prioritizing messages. It supports Gmail, Outlook, iCloud, Exchange, and other providers, making it relevant if your accounts extend beyond Google and Microsoft.
Canary provides its own email interface, so try its reading, search, and sending workflow before switching. Its AI can prepare replies and summarize messages; you review outgoing replies before sending. Automatic prioritization helps surface messages without writing a reply for you.
The free plan covers core email, while ongoing AI access requires an upgrade.
Price: Growth costs $36/year, equivalent to $3/month. Pro+ adds security features for $100/year. A seven-day trial includes paid features.
Can You Trust AI in Your Inbox?
Check three kinds of access: reading mail, organizing or deleting it, and sending on your behalf. ChatGPT’s documented send flow lets you review the draft before sending; Claude asks by default. Claude also offers tool permission controls to allow supported actions automatically, require approval, or block them, subject to workplace policies.
A widely reported February 2026 incident, in which Meta researcher Summer Yue said OpenClaw deleted emails against her instructions, shows why these controls matter.
Also check retention and model training. Anthropic says Google connector data is stored with its associated chat and is not used to train its models. If you opt into training on a personal plan, copied content or Claude’s answers containing connector information may still be used. Review both the email tool’s and the assistant’s policies.
To stop future access, disconnect the tool in your assistant and revoke its access through the service you connected; a workplace administrator may need to help. Review saved automations separately. See the AI email organizers guide for the privacy breakdown.
Before connecting, ask:
- Can it send without approval?
- Can it change or delete mail without asking?
- Can I undo its actions?
- Can I review an activity log?
- Can I disconnect and stop its automations?
Use Clean Email to Turn Recommendations Into Bulk Cleanup
An assistant can explain which newsletters look unnecessary. Clearing thousands of messages, unsubscribing from many senders, and maintaining cleanup rules requires tools built for that work.
Clean Email brings 12 years of email-cleaning experience to ChatGPT, Claude, and Codex. It gives your assistant tools for clearing a large backlog and unsubscribing from many senders across Gmail, Outlook, Yahoo, iCloud, AOL, and other providers.
Start with requests such as:
- “What’s the most impactful cleanup I can do right now?” Your assistant gathers top senders, subscriptions, and mailbox data, then explains the options.
- “Find messages from these senders older than a year.” Combine sender, date, size, and other criteria before approving a bulk deletion.
- “Unsubscribe me from these senders.” Clean Email handles multiple subscriptions, including blocking senders that ignore unsubscribe requests.
- “Create the same cleanup rule in all my connected accounts.” Review the criteria and actions before saving the rules.
Approved bulk cleaning and unsubscribing continue in the background, even if they take hours and you close the chat. Saved rules handle future matching mail according to the settings you approve.
Clean Email does not sell your data or show ads. It has full mailbox access and can provide full message bodies to your assistant when needed; it does not store email bodies. Your AI provider handles information received through the connection under its own policies.
Clean Email is free to try. To get started, connect Clean Email to your AI assistant.
💡 Tip: Want to keep clutter from returning? See the AI organizers guide for ways to organize email with AI and ongoing rules.
