## Free Blocks

Free Blocks tackles the tedious part of meeting planning: telling other people when you are free. Instead of writing out time ranges by hand, you connect your primary Google Calendar and Free Blocks reads your busy periods, then generates a tidy availability table you can paste into an email or share as a personal booking page. It reads the tone of the product well — the company describes it as a way to compose emails with beautiful tables that show when you are free, and it can also block off whole days when you know you are unavailable.

Beyond the core calendar sharing, Free Blocks ships as a small ecosystem: a personal booking page, a Google Workspace app available in the Workspace Marketplace, a Chrome extension and a Slack app. That means teammates and clients can see openings and grab a time without leaving the tools they already use, which is the main reason teams choose it over heavier scheduling suites.

The product positions itself as simple and approachable, targeting individuals, small teams and anyone who coordinates meetings across companies. There is a free tier — the company markets it heavily with "try us out, it's completely free" — and a pricing page plus a contact-sales path for larger or team deployments. If you already live in Google Calendar and Slack, the value is mostly in removing friction rather than in advanced routing, round-robin or complex meeting-type logic.

**Pricing & Plans:** Free plan available (the site promotes a completely free tier for individual use). A pricing page and a contact-sales option exist for team or business needs; check the site for current plan details and limits.

- **Google Calendar availability sync:** Connects to your primary Google Calendar to detect busy periods and generate accurate free-time blocks automatically.
- **Personal booking page:** Publish a link where clients and colleagues can see your openings and book a slot themselves, removing email back-and-forth.
- **Slack and Google Workspace apps:** Share availability and schedule from inside Slack, Gmail and the Google Workspace Marketplace without switching tools.
- **Chrome extension:** Grab your availability blocks while browsing and drop them straight into an email or message.
- **Full-day blocking:** Mark entire days as unavailable so only genuinely open time is offered when you build an availability table.

**Strengths:** Direct Google Calendar and Gmail integration with no extra service to sign up for; Free tier makes it low-risk to adopt for individual use; Apps for Slack, Chrome and Google Workspace meet people where they work; Simple, approachable flow for people who dislike complex scheduling suites

**Limitations:** Primarily Google-centric — Microsoft 365 or Outlook users get little benefit; Fewer advanced features than dedicated scheduling platforms (routing, complex meeting types); Team and business pricing details require contacting sales

## 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
