## FormalizeIt

FormalizeIt targets a very specific annoyance: you know what you want to say, but the draft in your compose window sounds blunt, careless or too casual for the recipient. The add-on drops a button into Gmail's compose toolbar; press it and your text is sent to OpenAI, which returns a rewritten version that reads as more professional and more respectful while keeping the original intent. It is deliberately minimal — there is no dashboard, no template library and no tone picker, just one action on the draft you already wrote.

Because the extension uses OpenAI directly, you register with OpenAI and paste your own API key. That means your usage is billed by OpenAI rather than by the developer, and the extension itself can be installed at no cost. The trade-off is that you need an OpenAI account and basic comfort with API keys before it is useful.

The listing is small and has not been updated since August 2023, so treat it as a single-purpose utility rather than a maintained email suite. It handles the common case well: quick politeness and professionalism upgrades on short business emails, replies to managers or clients, and any situation where an informal draft needs to be presentable before it goes out.

**Pricing & Plans:** The extension is free to install. You supply your own OpenAI API key, so any model usage is billed by OpenAI at their standard API rates; the developer does not charge a subscription.

- **One-button rewrite in Gmail:** A magic-button action is added to the Gmail compose window, so you can rewrite the draft you are already writing without switching tabs or copying text elsewhere.
- **Professional and polite tone output:** The rewrite targets professionalism and respect, turning terse or overly casual phrasing into wording better suited to colleagues, managers and clients.
- **Powered by your own OpenAI key:** You connect the extension to OpenAI with your own API credentials, keeping usage costs transparent and under your control.
- **No learning curve:** There are no settings to configure beyond the API key and no new writing interface to learn — it works inside the Gmail compose box you already use.
- **Chrome-native install:** Installs from the Chrome Web Store as a small extension with a light footprint, and the developer discloses that it does not sell or misuse your data.

**Strengths:** Free to install and stays inside the Gmail compose window; Requires no new writing tool or workflow to learn; Uses your own OpenAI key, so costs stay transparent; Developer discloses that data is not sold or reused outside core functionality

**Limitations:** Requires an OpenAI account and a manually configured API key; No tone, length or style controls — one fixed professional rewrite; Last updated in August 2023 and has very few users, so long-term maintenance is uncertain

## Missive

Missive was built around a simple observation: email was designed for individuals, but most businesses run on shared inboxes that several people need to work on together. Missive turns those inboxes into team workspaces. Every email becomes a conversation where colleagues can discuss the reply internally, assign ownership, and see who is handling what. Team inboxes, shared tasks, private notes, and tags replace forwarded messages and side-channel chat apps, keeping context attached to the message it belongs to.

The platform is a full email client as well, supporting Gmail and Google Workspace, Microsoft 365 and Outlook, IMAP, plus SMS and other channels. On top of that sits an automation layer: rules can handle repetitive routing and tagging tasks automatically, and integrations with more than 25 apps such as Stripe and CRMs pull extra context into the inbox. The AI assistant is positioned as a real assistant rather than a generic sidebar, gathering context from connected tools via MCP before drafting a reply.

Missive is popular with small and mid-sized businesses that live in email, including accounting, legal, real estate, logistics, and professional services firms. Customers include teams of 100-200 and above, and the company publishes customer stories, a status page, and a partner program for certified consultants.

**Pricing & Plans:** Missive offers a free trial so teams can invite colleagues and evaluate the product before paying. Paid plans are subscription-based per user, with tiers determined by team size and required features. Exact rates are published on the Missive pricing page.

- **Shared team inboxes:** Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
- **Internal conversation on emails:** Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
- **Tasks and workload visibility:** Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
- **Automations and rules:** Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.
- **AI assistant and integrations:** An AI assistant that gathers context from connected tools via MCP, plus integrations with 25+ apps including Stripe and CRMs.

**Strengths:** Turns shared inboxes into genuinely collaborative workspaces with internal chat; Combines email, tasks, automations, and integrations in one client; AI assistant pulls context from connected tools rather than acting as a generic sidebar; Strong fit for small and mid-sized teams that run on email

**Limitations:** Pricing is per-user and scales up with larger teams; The depth of features can be more than a very small team needs
