Problem
Solution
TaskMail helps you manage tasks, logs, and categories tied to threads—inside the Gmail you open every day.
TaskMail
From inbox badges to the thread panel and the extension side panel—follow the real UI in one pass.
Actual UI
Skip the extra task tab: update progress on the same screen as the message. Use this clip to map the main paths first.
Features
Inbox, the message you’re reading, and the extension side panel—stay in Gmail the whole time.
Scan progress at a glance
Thread-level task progress appears as badges so you know what to open next.
Tied to the open thread
Update status, notes, logs, and categories per thread right beside the message.
Multiple owners for billing
Switch workspaces, invites, the task list, and reply snippets from the extension panel. Multiple owners are supported so Stripe billing no longer depends on a single person.
Body accordion with previews
The Mail tab lists the thread newest-first. Bodies collapse into an accordion; images and PDFs preview in-sidebar, and every attachment has a download icon.
Unacknowledged ones surfaced
Fired-but-unacknowledged reminders aggregate into a notification bar at the top of the side panel. Tap to open a list and acknowledge individually or all at once.
Inbox
Thread-level task state shows in badges so you can move forward without losing context. Email-heavy work stays easier to scan.
How it works
Add TaskMail from the store and sign in—then manage tasks right in Gmail.
Find TaskMail in the Chrome Web Store and click Add to Chrome. You keep using the same browser you already use every day.
Sign in with a one-time code sent to your email, or sign in with your Google account—whichever you’re offered on screen.
From the inbox progress badge, the "Open task" button in the thread header, or the reminders bar in the side panel—any of three entry points lets you link tasks to that email and update progress or notes.
Thread view
Update status, notes, and activity per thread without copying email into another tool. Stay in your reading flow all the way to done.
Use cases

Want to avoid another heavyweight SaaS rollout.
Add Chrome, invite people, stay in Gmail
Security
TaskMail has completed a CASA Tier 2 security assessment by a third-party assessor (ADA CASA Assessor). Cloud data lives on Supabase, protected by row-level security (RLS) and HTTPS. Payments are processed by Stripe — we never store card numbers. Email bodies and attachments are fetched from the Gmail API on demand to render in your browser only; they are not stored on our servers.

FAQ
TaskMail targets Gmail in Google Chrome at mail.google.com. As a Manifest V3 extension, other browsers aren’t supported. Your Chrome profile Google account should match the Gmail tab you’re using.
You can try core features with limits on tasks, logs, snippets, teams, and members. Details follow in-app.
Team workspaces, invites, Personal Pro, Starter, Team, and Business—and current limits—are defined in the extension UI. Subscribe, change, or cancel via Stripe from the in-extension billing flows. We don’t store full email bodies for reading; see the Privacy Policy.
Every member with the owner role can access the Stripe billing portal. A workspace can have multiple owners, so ownership (and billing access) can be handed over by promoting another member. Demoting or removing the last remaining owner is blocked.
They aren’t. The Mail tab in the side panel fetches email bodies and attachments from the Gmail API on demand and renders them in your browser only. We do not retain bodies or attachments on our servers.
