About InboxAgent and HabitStack

On a busy day some are never answered, and you are the one answerable when a real lead goes quiet. InboxAgent watches the mailboxes you already have, on Microsoft 365, Gmail,...

Features and specs

What each product offers, as listed by its team.

InboxAgent 11 features
HabitStack 5 features
  • Triage-based inbox system
    Every email is sorted into one of three things: a sales lead, something else that needs a person, or noise. Leads land on a Leads board and everything else on Follow-ups, each with an owner and a stage. Read-only throughout, nothing is moved.
  • AI Classification
    AI works out what each email is once the rules have cleared the obvious noise. Anything it is not confident about is marked Needs review and waits for a person. Your team's corrections stick and become rules and sender signals you can see.
  • Pricing Model
    $20 a month for your whole organization, including the first mailbox. $5 for each additional mailbox. Users are free, no per-seat charge and no overage. 7-day free trial.
  • Noise Filtering
    Newsletters, bulk mail, known marketing senders and auto-replies are caught by rules you control and set aside before the AI is ever called. Every decision is recorded so you can see what was filtered and why.
  • Gmail Integration
    Reads Gmail and Google Workspace mailboxes, shared and individual, read-only and Google-verified. Each person authorizes their own. Nothing is moved and your team keeps working in Gmail.
  • Outlook Integration
    Reads Microsoft 365 mailboxes, including shared mailboxes like info@ and sales@, read-only. Each person authorizes their own. Nothing is moved and your team keeps working in Outlook.
  • zoho crm
    Sales inquiries become leads in your Zoho CRM as they arrive, matched to an existing record where there is one rather than creating a duplicate. Zoho Desk is supported alongside it for service requests.
  • HubSpot Integration
    Sales inquiries flow into HubSpot as contacts and deals, matched against existing records. Works on HubSpot's free tier, so there is nothing extra to buy.
  • IMAP Support
    Connects to any standard IMAP mailbox, not just the major providers. Read-only, with the same Leads and Follow-ups boards as everywhere else. Four mailbox types in total: Microsoft 365, Gmail, Zoho Mail and IMAP.
  • Follow-up Automation
    Anything that needs a person and is not a sales lead is detected and placed on the Follow-ups board with an owner, and stays open until it is marked done. Invoices, renewals, contracts, supplier requests, legal notices. The automation is in the finding and the routing. InboxAgent never sends email on your behalf.
  • Read-Only Access
    Read-only access to every connected mailbox. InboxAgent does not move, migrate, archive or delete anything. Two-factor authentication, role-based per-mailbox access, CASA security assessment completed.
  • Simple and focused design
    HabitStack offers a clean, minimalist interface focused specifically on habit tracking, making it easy to understand and use without unnecessary complexity or feature bloat.
  • Stack-based habit building approach
    The app uses a habit stacking methodology, encouraging users to build new habits by linking them together in sequences, which is a proven behavioral science technique for forming lasting habits.
  • Multi-language support
    HabitStack provides support for multiple languages (as evidenced by the /en URL path), making it accessible to a broader international audience.
  • Web-based accessibility
    Being a web-based application, HabitStack is accessible from any device with a browser without requiring users to download or install a native app, reducing friction for getting started.
  • Free to use
    HabitStack appears to offer a free tier for habit tracking, lowering the barrier to entry for users who want to start building better habits without a financial commitment.

Possible disadvantages

  • Limited brand recognition
    HabitStack is a relatively lesser-known tool compared to established habit trackers like Habitica, Streaks, or Loop, which means fewer community resources, reviews, and user-generated tips are available.
  • Limited feature set compared to competitors
    As a simpler, more focused tool, HabitStack may lack advanced features found in competitors such as detailed analytics, social accountability features, integrations with other productivity tools, or gamification elements.
  • Uncertain long-term viability
    As a smaller, independent product, there may be concerns about the long-term sustainability and continued development of the platform compared to apps backed by larger companies or well-funded teams.
  • Limited offline functionality
    Being a web-based application, HabitStack may have limited or no offline functionality, which can be problematic for users who want to log habits when they don't have an internet connection.
  • Fewer integration options
    HabitStack likely lacks integrations with popular productivity ecosystems like Apple Health, Google Fit, Zapier, or calendar apps, limiting its ability to fit seamlessly into a user's existing workflow.

Questions & Answers

As answered by people managing InboxAgent and HabitStack.

Why should a person choose your product over its competitors?

InboxAgent's answer

  • Nothing to migrate and no new app for your team to adopt. They keep working in Outlook or Gmail exactly as before.
  • Priced per organization, not per seat. $20 a month including your first mailbox, $5 for each additional mailbox, unlimited users.
  • It covers shared addresses like info@ and sales@ as well as everyone's own inbox, on Microsoft 365, Gmail, Zoho Mail or any IMAP mailbox.
  • A salesperson can act on a lead without being given the mailbox, which usually also holds bank correspondence and password resets.
  • It works with or without a CRM. If you use Zoho CRM, Zoho Desk or HubSpot, leads flow there as well.

HabitStack's answer:

HabitStack doesn't overwhelm you with hundreds of undone tasks. It filters out the noise and helps you focus on what's most important.

What makes your product unique?

InboxAgent's answer

It is read-only. InboxAgent reads the mailboxes you already have and never sends mail from them, never moves a message, and never files or deletes anything. Most tools in this category work by forwarding your mail into their own system, after which your own mailbox stops being the record of what arrived. Nothing here changes your mailbox.

For Microsoft 365, Gmail and Zoho Mail that is enforced by those providers rather than promised by us. The permissions we request are read-only, so you can check it on the consent screen before you click Allow.

HabitStack's answer:

It helps you adopt the uncommon habits that effective leaders use to push forward important goals, even though they're busy.

How would you describe the primary audience of your product?

InboxAgent's answer

Businesses whose sales inquiries arrive by email, at shared addresses like info@ and sales@ as well as in individual inboxes. Typically service businesses that sell by email: agencies, professional services, trades and field service, suppliers and distributors.

It fits particularly well where email is the main source of leads and there is no proper place to manage them. Every lead lands on a board with an owner and the original email attached, moves through stages you name yourself, carries up to ten fields of your own, and can be exported to CSV at any time.

What's the story behind your product?

InboxAgent's answer

Sales inquiries arrive in the same mailbox as invoices, supplier mail and noise. Everyone can see them and nobody owns them, so on a busy day some are never answered, and the business often finds out only when a customer goes elsewhere.

InboxAgent exists to answer one question about that mailbox: who owns this email, and has anyone actually dealt with it.

Which are the primary technologies used for building your product?

InboxAgent's answer

.NET on Microsoft Azure App Service. Microsoft Graph, the Gmail API, the Zoho Mail API and IMAP for mailbox access, all with read-only permissions. OpenAI for classification.
