## Clevermail

Clevermail is a browser extension distributed through the Chrome Web Store that layers an AI writing layer on top of Gmail. Instead of starting every message from a blank compose window, you give the assistant a brief instruction and some context about your business or the recipient, and it returns a complete, professionally worded email draft you can review, tweak and send.

The extension is aimed at people who live in their inbox — sales teams, founders, freelancers, recruiters and support staff — and who lose time finding the right phrasing for routine messages. Because the drafts are generated from the context you supply, the aim is output that reads as if you wrote it rather than as generic template text. Multilingual support means you can produce a message in a language other than the one you think in, which is useful for international clients and partners.

Clevermail installs like any other Chrome extension and works inside the Gmail interface, so the typical workflow of reading a thread, replying and sending stays uninterrupted. The free tier covers light everyday use, with paid options for people who write a high volume of email. The extension is published by the team behind clevermail.co, has a small but positive user rating on the Chrome Web Store, and requires permissions to handle personally identifiable information and personal communications, which is expected for an email assistant — check the developer's privacy policy if data handling matters for your organisation.

**Pricing & Plans:** Freemium. A free tier covers everyday email drafting, with paid plans unlocking higher usage limits and advanced features. Check the Chrome Web Store listing or clevermail.co for current plan details and prices.

- **AI email drafting in Gmail:** Give a short instruction plus context about your business or recipient and receive a complete, professionally phrased email draft ready to review and send, without leaving the Gmail compose window.
- **Personalized, on-tone output:** Drafts are generated from the context and inputs you provide, so the result targets your actual situation and relationship rather than producing generic boilerplate copy.
- **Multilingual support:** Compose and generate messages in languages beyond your native one, which helps when corresponding with international clients, partners or colleagues.
- **Send directly from the extension:** Review the generated draft and send it from within the extension flow, keeping the read-reply-send loop inside Gmail instead of switching between apps.
- **Lightweight browser integration:** Installs as a standard Chrome extension with a small footprint, so it adds AI assistance to the Gmail interface you already use without a separate dashboard.

**Strengths:** Generates complete, professional Gmail drafts from a short prompt and context; Works inside Gmail, so there is no separate app or workflow to learn; Multilingual output is useful for international correspondence; Free tier lets you test it on everyday email before paying

**Limitations:** Requires access to personal communications and personal information, which some organisations will not permit; Only useful if you already work in Gmail on Chrome; Small user base and a single developer listing, so long-term support is less proven

## Smart Assistant by Mailbutler

Mailbutler is an email productivity extension for Apple Mail, Gmail, and Outlook, and its AI component is the Smart Assistant. Rather than being a standalone chatbot, the assistant is embedded in the compose and read views of the inbox you already use. It can compose an email from a few short keywords, draft a reply framed as positive, negative, or neutral, summarize an entire thread, or correct grammar and phrasing in a draft — all without switching apps or copying text elsewhere.

The AI layer is deliberately connected to the rest of Mailbutler's toolkit. Follow-up suggestions analyze tracked emails — opens, link clicks, and engagement patterns — then classify threads as high, medium, or low priority, and the Smart Assistant can draft the follow-up itself. That combination of tracking data plus generation is what makes the assistant useful in sales and client-facing work, where knowing who to chase matters as much as what to write.

The rest of the extension supplies email tracking, message templates, mail merge, smart timing, tasks and notes, shared inbox assignments, and signature marketing. On privacy, Mailbutler is ISO/IEC 27001 certified and GDPR compliant with servers in Frankfurt, Germany. Emails are still sent from your own server, message content is not analyzed or stored in the backend for general operation, and when you use the Smart Assistant the email body is sent to OpenAI only for that request, with email addresses replaced by dummy variables. Plans range from a free-forever Starter tier to paid Smart and Business plans, all starting with a free 14-day trial that includes every feature and no credit card requirement.

**Pricing & Plans:** There is a free-forever Starter plan plus a free 14-day trial with all features and no credit card. Paid tiers are billed per user per month (about $4 Starter, $7 Professional, $11 Smart, and higher Business pricing when billed yearly, with monthly pricing slightly higher) and available in USD or EUR. The AI Smart Assistant is included from the Smart plan upward; email tracking, templates, mail merge, tasks, and signatures are spread across the tiers.

- **AI drafting and reply generation:** Turn a handful of keywords or bullet points into a full, sendable email, and generate replies framed as positive, negative, or neutral depending on the situation.
- **Thread summarization:** Condense long email chains into the key points so you can catch up fast and respond without re-reading every message.
- **Grammar and tone correction:** The assistant rewrites and corrects your message for grammar, spelling, and phrasing before you hit send.
- **Smart Follow-ups:** Follow-up suggestions combined with open and click tracking tell you which threads are urgent, and the assistant can draft the follow-up for you.
- **Built into a full email toolkit:** The AI features sit alongside tracking, message templates, mail merge, tasks and notes, shared inbox assignments, and email signatures so your whole workflow stays in one inbox.

**Strengths:** Works inside Apple Mail, Gmail, and Outlook instead of forcing another app into your stack; AI drafting, summarization, and grammar checks are combined with tracking and follow-up prioritization in one place; Strong privacy posture: ISO/IEC 27001 certified, GDPR compliant, and servers located in Germany; Free 14-day trial unlocks all features with no credit card required

**Limitations:** Most genuinely useful AI features require a paid plan, and full automation sits on higher tiers; Free tier is limited, so the free-forever Starter plan is best treated as a lite entry point; Used for email drafting, email body text is transmitted to OpenAI (addresses are tokenized), which some compliance teams will want to review; Feature depth varies slightly by client since it is an extension layered over three different email apps
