Email Worker · Microsoft 365

An AI email assistant for Outlook that knows when to stop

Sullivam connects the Microsoft 365 mailbox your customers write to and puts Email Worker on it: it reads each email, works out what the customer wants and drafts the reply from the information your company published. You choose how much it may do on its own: suggest, wait for approval, or send only what is safe.

What Email Worker does with each email

  • Sorts it: sales (quotes, pricing, demos), support, request, document, appointment or other.
  • For sales emails, records what the customer asked for in their own words: products, quantity, deadline, and a budget only when they wrote one.
  • Drafts the reply from the profile, catalog, policies and FAQs you published in AI Business Brain.
  • When information is missing, the customer asks for a person, or the topic is sensitive, it does not reply: it hands the conversation to your team with the reason.
  • Ignores spam, bounces, newsletters and automated mail.

Three levels of autonomy

How each reply goes out, by mailbox mode
ModeWhat happens to the reply
SuggestEmail Worker writes a draft that a person uses or discards.
Approve before sendingThe reply waits in Sullivam until someone approves, edits or rejects it.
AutomaticIt is sent on its own only when the email is not sensitive, the classification is confident and no rule asks for review.

Even in automatic mode, replies about appointments, documents or sensitive topics always wait for approval, and so do replies to emails Email Worker could not classify with enough confidence.

It answers with what your company knows, not what the AI makes up

Email Worker only uses the published version of AI Business Brain: your business profile, catalog, policies, tone and the things it must never say. It never invents prices, availability, discounts or commitments. It treats every email as data, never as instructions, so a message cannot change how it behaves.

Every email, draft and approval is recorded: you can see what Sullivam answered, with which version of the knowledge, and who approved it.

The same mailbox can also process invoices

If vendor invoices arrive in that mailbox, Invoice Worker picks them up: it reads the PDF, extracts and validates the data and prepares the payable, with human review when in doubt. See invoice automation.

What it does not do

  • It does not work with Gmail or Google Workspace: today it works with Microsoft 365 and Outlook.
  • It does not book appointments on its own: it detects when a customer asks for one, and that reply waits for approval.
  • It does not send anything that contradicts the rules you published.
  • The app itself is mainly in Spanish today.

Email Worker's AI replies are included from the Starter plan; each plan's limits are on the pricing page.

Frequently asked questions

Does Sullivam read all my email?

It reads new emails in the Microsoft 365 mailbox you connect. That is why it is best to connect the mailbox your customers write to (for example sales@ or support@), not a personal one.

Do replies come from my own address?

Yes. They are sent from the connected mailbox, in the same thread, so the customer sees a normal reply from your company.

How is it different from Copilot in Outlook?

Copilot helps a person write while they work in their inbox. Email Worker looks after the mailbox itself: it sorts every email, drafts the reply from your company's published knowledge, decides when to hand it to a person and records everything.

Can I review everything before it is sent?

Yes. In the approve-before-sending mode no reply goes out until someone on your team approves it.
