Harness Email

Your sent folder already knows
what the ledger does not.

This is not another inbox to live in. Harness does not manage your email and it is not trying to replace the one you have. It reads the conversation around the work, so the follow-up knows what was already said.

An accounting system can tell you an invoice is 34 days late. Only the thread can tell you the customer replied on Tuesday and promised Friday. A chase written without that is the one that costs you the account.

01 · What the thread adds

Four things a ledger cannot see.

Whether they have already replied

The single most expensive mistake in chasing is the reminder that goes out after the customer has answered. Harness reads the thread first, so an invoice with a reply on it is treated as a conversation, not an overdue line on a report.

What was promised, and when

A customer who said Friday gets held until Friday. A customer who said Friday three weeks ago gets a different message from one who said it yesterday.

The tone you actually use

Your sent folder is the only honest record of how you write to people. A client of ten years does not get the wording you use with an account that has gone quiet twice.

What is still outstanding

Threads with a question in them that nobody answered. Quotes that went out and got no reply. The follow-ups that fall off the end of a busy week.

02 · What it will not do

Reading is not the same as running your inbox.

It does not take over your mail

No rules, no filing, no archiving, no deleting. Harness reads the threads tied to the work you asked for and writes drafts. That is the whole remit.

It sends from you, not from us

Approved messages go out through your own account, so the reply lands in your inbox and the record sits in your sent folder. Nothing leaves from a Heoka address.

Approval first, autonomy earned

Every draft waits for your tap to begin with. Only a gentle early reminder can ever earn the right to send on its own, and only if an owner allows it. Anything sensitive always comes back to a person.

You can pull the plug

Revoke the connection from inside Gmail whenever you like and Harness loses access the same moment. It never sees your password.

03 · Questions

Straight answers.

Does Harness read my whole inbox?

No. It reads the threads connected to the work you have asked it to do, such as the conversation around an invoice or a quote. It is not a mail client, it does not index everything, and it cannot see an account you have not connected.

Can it send email on my behalf?

It drafts. The draft waits in your approval queue and goes out from your own address once you tap send. Once a gentle early reminder has built up a run of approvals, an owner can let that one stage send on its own. Everything sensitive still comes to you.

Which email accounts are supported?

Gmail and Outlook are both live, and short replies to Microsoft Teams chats go through the Outlook connection. Say which one you use before you subscribe and we will tell you where you stand.

Is my email used to train an AI model?

No. Your data is not sold and is not used to train third-party models. Your mail stays in your own account. Harness stores only the operational state it needs to run the work, such as queues, approvals and encrypted connection credentials, and it never stores your password.

The context pays for itself on invoices first.

Connect Gmail alongside Xero, and the overnight chase already knows who replied. What it learns doing that becomes the company brain.
