## 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

## superReply

superReply is a browser extension that adds an AI reply assistant to the tools people already work in. Once installed and signed in, it appears directly inside Gmail and Outlook web inboxes, and it also works across LinkedIn, WhatsApp, Slack, Upwork and Fiverr. Instead of composing a reply from scratch you click into a message, let the extension suggest options, adjust the tone of voice to match the situation and send the version that fits.

The product is aimed squarely at people who answer the same kinds of messages all day: customer care agents, sales teams, freelancers juggling client threads and anyone who wants to clear an inbox faster. Its selling points are speed, tone matching and privacy. The extension only accesses the emails you explicitly choose to use it on, replies are not stored on superReply's servers, and the company says it applies industry-standard encryption.

The service is free to start, with up to 90 AI-powered replies per month at no cost. Paid plans remove that ceiling and unlock advanced tone controls, billed monthly or annually, and there are team plans for managing multiple seats. Each user installs the extension on their own browser with their own account so replies stay personalised, and cancellation is a one-click action from account billing settings.

**Pricing & Plans:** Freemium. Free to start with up to 90 AI email replies per month. Paid plans unlock unlimited replies and advanced tone controls, billed monthly or annually, with team plans available for multiple seats. Cancel anytime from billing settings.

- **Reply suggestions inside your inbox:** The extension appears directly in Gmail and Outlook web, so you never leave the thread you are answering.
- **Tone matching:** Pick the tone of voice that fits the situation — professional for a client, casual for a friend — and the suggestions adapt.
- **One-click smart responses:** A single click surfaces several ready-to-send reply options so you are never stuck staring at a blank compose box.
- **Works beyond email:** Beyond Gmail and Outlook, superReply integrates with Chrome, WhatsApp, Slack, LinkedIn, Upwork and Fiverr.
- **Privacy-first handling:** Replies are not stored on superReply's servers, the extension only reads emails you choose to use it on, and data is encrypted in transit.

**Strengths:** Free tier covering up to 90 AI replies every month; Lives inside Gmail and Outlook, so there is no new app to learn; Tone controls adapt suggestions to professional or casual contexts; Does not store generated replies on its own servers

**Limitations:** Requires installing a Chrome extension rather than working as a standalone web app; Advanced tone controls and unlimited replies sit behind the paid plans; Each user needs their own account, so team-wide rollout takes a little setup
