The Email appPart of DukeOS, the AI operating system for business: CRM, ERP and AI agents in one system. From $49 a month per business
Send an email from any customer's page. It goes out in your business's name, replies come back to the person who sent it, and the email is kept on the customer's timeline.

01Duke in Email
Ask for an email in plain words. Duke reads the customer's history, writes it or fills one of your templates, and shows you exactly what will go out, in your business's name.
Who decides
Say what you want to tell someone. Duke writes the email, and you see the subject and every word before approving.
Duke checks the customer's recent emails and WhatsApp messages first, if your role may read them, so a follow-up never repeats what you already said.
An agent can email your approved templates on its own, like renewal reminders, up to a limit per run. Emails Duke writes itself still wait for you.

What Email does, part by part, on screens from our live demos.
Your name on it
The sender name is your brand, so customers know who is writing. Replies go to the staff member who sent the email, straight to their own inbox. Sending runs through Resend or any SMTP service you already use.
Email settings
Timeline
Each email is queued, then marked sent or failed. It appears on the customer's timeline only once it has actually been sent, so the history shows what the customer received.

Templates
Pick a message template and the email fills itself with the customer's name, your business name and your own name. If a placeholder still has nothing in it, the email isn't sent until you fill it.
With Duke: ask it to fill a template for a customer and it names any detail that's missing.
Before sending
Drafted by Duke
When Duke writes emails, each card shows the exact recipient, subject and text. There's one card per customer, and you can approve them one by one or all together.
