Can AI send email on behalf of your company? How authorization works

When people talk about letting an AI work for the company, one question comes up fast: what about email? Is it going to write to my customer without me seeing it? Promise a deadline nobody agreed to? Answer a supplier in the wrong tone?

Technically, yes, an AI can send email, and Will does. The question that matters is who authorizes what. Here’s how Will works in email, and how to set up your company’s rule.

How Will works in email

Will reads the company’s Gmail or Outlook and picks out the emails that need a reply. For each one, it gathers what it needs from the ERP, the order and the conversation history, writes the reply with the source of each piece of information and sends it from the inbox you already use. Then it tells you what it did.

Outside email, it’s the same. If the due date on a ClickUp card changed, Will updates the card and lets whoever owns it know. If the supplier sent a new date, it updates the order in the ERP. You get the "done" instead of one more task.

Will does it and tells you

Will’s rule fits in two sentences: You ask, Will does it. Will asks, you decide. In email, that means Will does the whole job, from looking things up to hitting send, and only calls you in when it needs a decision from you.

An example at a fictional company, Lume Casa. A customer, Ana Paula R., asks about order #1842. Will finds the order in Bling, sees it’s waiting on linen from Têxtil Norte and reads the supplier’s latest email in Gmail. It tells the customer what’s happening, without promising a date nobody confirmed, and lets Bia in customer service know: "I replied to Ana Paula about #1842. I’m chasing the date for the linen."

The classic case: the late supplier

Chasing suppliers is one of the most repeated emails in any company, and one of the easiest to lose in the middle of the day.

The linen from Têxtil Norte should have shipped yesterday, nobody has confirmed a new date, and two orders depend on it. Will sends the email asking for the new delivery date right away and lets Caio in purchasing know: "I asked Têxtil Norte for the new linen date. I’ll tell you when they reply."

When Têxtil Norte replies, Will updates orders #1842 and #1851 in Bling, lets the customers who ordered know and tells Caio: "The linen arrives Thursday. I updated both orders and let the customers know."

How to set up your authorization rule

With or without Will, it’s worth putting this in writing before you let any AI write on behalf of the company. I’d split it into three groups:

• Does it and tells you after: answering a customer about an order, asking a late supplier for a new date, confirming receipt of an invoice, reminding someone on the team about a deadline.
• Brings it to you: anything you mark as sensitive, like a proposal with a new deadline or the first message to a big customer.
• Always with you: payments, discounts, pricing, cancellations and anything that commits money.

The first group is the biggest, because that’s where the day’s running around is. Review the list whenever you like, and whenever someone joins or leaves the team.

What doesn’t change

• Will gathers the boletos (bank slips), uses Open Finance, regulated by Brazil’s Central Bank, to check what has already been paid, and flags what’s coming due. You’re the one who pays.
• Every action gets a receipt: who asked, what was done, in which system, when and under which rule.
• When information is missing, Will says what it couldn’t see, instead of making up a deadline.

In the end, it’s trust with a record: you know what Will can do, what it did and who authorized it. The details are in what Will does on its own, Sources and receipts and Security and LGPD (Brazil’s data protection law). To see everything Will does in email, read Will in Gmail. And if chasing suppliers takes up most of your day, get started and leave it with Will.
