## MAIL EVOLVED

MAIL EVOLVED takes a deliberately minimal approach to AI email writing. Instead of building a whole email client around the model, it stays as a thin layer on top of Gmail. Once the extension is installed and your OpenAI API key is saved in its settings, it watches for the moment you begin composing a reply. At that point it adds a set of buttons beside the normal reply button, each representing a different kind of answer — for example a brief acknowledgement or a fully custom response generated from a prompt.

Because the extension talks to the OpenAI API with your own credentials, the costs scale directly with your personal usage rather than a vendor subscription. The version currently published in the Chrome Web Store is 1.1, last updated in May 2023, and it is a small 20 KB package that targets the classic GPT-3 era OpenAI endpoints. It was built by an individual developer and has a small install base, so treat it as a handy utility rather than an enterprise-grade tool.

Privacy is straightforward: the developer states that no personal information is collected through the extension, but email content you submit is sent to OpenAI for processing, so their privacy policy applies to that data. If you want a no-frills way to speed up routine replies without adopting another inbox app, MAIL EVOLVED is a pragmatic choice.

**Pricing & Plans:** Free to install. You must supply your own OpenAI API key and pay OpenAI for the tokens consumed. No subscription tiers are offered by the extension itself.

- **Reply buttons inside Gmail:** A row of generation buttons appears next to the standard reply control whenever you start answering an email in Gmail.
- **Bring your own OpenAI key:** You paste your own OpenAI API key once in the settings; all requests are billed to your own OpenAI account.
- **Multiple reply styles:** Each button maps to a different type of answer, from a short acknowledgement to a free-form custom response.
- **One-click insertion:** Generated text is placed straight into the Gmail reply box so you can review, edit, or send it immediately.
- **Featherweight install:** The whole extension is roughly 20 KB and adds no background services beyond the API calls it makes on demand.

**Strengths:** Free to install with no vendor subscription; Works directly inside Gmail with barely any setup; Uses your own OpenAI key, so usage and cost stay transparent; Very small footprint and no account signup required

**Limitations:** Requires a working OpenAI API key before it does anything; Extension version dates from 2023 and has a small user base; Gmail-only; no support for Outlook or other mail clients

## 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
