Leads arrive at info@, at sales@, and in each salesperson's own inbox, mixed in with client questions, invoices and noise. 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,...

Features and specs

What each product offers, as listed by its team.

Readless 10 features
InboxAgent 11 features
  • One digest from newsletters, Substack, and RSS
    Point email newsletters, Substack publications, and RSS feeds at one place and get a single briefing back, instead of checking each source separately.
  • Synthesis editorial briefing (Max)
    Reads every source you follow and writes one connected story with citations back to each one, rather than ten stacked summaries.
  • Cross-source de-duplication
    When several newsletters cover the same story, Readless merges them into one item and links each source, so you don't read the same thing four times.
  • Ad and clutter removal
    Strips ads, tracking pixels, and footer noise before the digest reaches you.
  • Digest languages
    Read a source in any language and get the summary in yours. Auto keeps each source in its own language; pick a single language to unify everything.
  • Custom summary depth
    Choose Concise bullets or Detailed context, set per schedule.
  • Custom summary instructions (Max)
    Steer the tone and focus of a digest in up to 2,000 characters per schedule.
  • Multiple digest schedules
    Split work, investing, and personal reading into their own briefings, each with its own time and sources. Up to 3 on Pro, 8 on Max.
  • Private newsletter address
    A dedicated @mail.readless.app address collects your newsletters and keeps your personal inbox clean.
  • Flexible delivery control
    Pick the weekdays and delivery time for each digest, morning, noon, or evening.
  • 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.

Questions & Answers

As answered by people managing Readless and InboxAgent.

Why should a person choose your product over its competitors?

Readless's answer

RSS readers like Feedly collect your sources but still make you read everything. Inbox filters move newsletters into folders without shortening them. Readless does the reading for you: it summarizes, removes duplicate coverage, and delivers one digest on your schedule. It handles email newsletters, native Substack, and RSS in the same place, writes in nine languages, and lets you run separate digests for separate parts of your life. Pro is $4.90/month; Max adds the Synthesis briefing and custom instructions for $9.

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.

How would you describe the primary audience of your product?

Readless's answer

People who follow more than they can keep up with. That includes investors tracking market newsletters, engineers and founders following tech Substacks, operators watching several industry briefings, and anyone whose inbox has quietly turned into a backlog. If you subscribe to 10, 30, or more newsletters and open only a fraction of them, Readless is built for you.

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?

Readless's answer

It started with a full inbox and a simple problem: subscribing to good newsletters is easy, but keeping up with them is not. The writing you actually wanted gets buried under senders you meant to read and stories you already saw somewhere else. Readless was built to turn that pile into one short, organized read you finish, so following a source doesn't cost you an hour a day.

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.

What makes your product unique?

Readless's answer

Most tools stop at collecting your feeds or summarizing one email at a time. Readless reads across everything you follow at once. It merges stories that several newsletters cover, strips the ads, and organizes what's left by topic, so you read one briefing instead of twenty emails. On Max, the Synthesis option goes a step further and writes a single connected story across all your sources, with citations back to each one. You can also read any source in your own language, out of nine options.

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.

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.
