The Agentic Email Platform
Describe an email job once. Get sh*t done.
You set the boundary. It works inside it.
A workflow is created paused, and every turn it takes is on the record in your mailbox — what it matched, what it sent, and why it stopped.
- 01
Describe the job
A trigger, your instructions in plain words, and the goal that ends it. No rules engine to learn.
- 02
The agent runs itGoal met
It matches the email, replies from how you already write, and chases silence once before letting the thread go.
- 03
It hands back what is yoursNeeds you
A price, a refund, a legal call, a sender who is upset — it stops, marks the thread, and tells you why in one sentence.
Anything you answer more than once
These are not templates. You describe the job in your own words, and the agent works out when it applies, replies in your voice, follows up if the thread goes quiet, and hands it back the moment it needs you.
“Answer the questions we already cover in the docs, and send anything about billing to me.”
Two answered from the docs and closed.
The duplicate charge came straight back to you, unanswered.
Everything your inbox needs to run itself
Agents that reply and follow up, AI that reads every email for you, and a mailbox that plugs into the tools you already use.
Agents that do the work
Hand over the conversations you answer again and again, and keep the final say.
Agentic workflows
Describe an email job once: a trigger, instructions in your own words, and a goal. An agent replies in your voice until the goal is met.
Follow-ups that stop themselves
It chases silence on your schedule and never nudges someone who already replied.
Hands it back when unsure
A price, a legal call, an upset sender: it stops, marks the thread "needs you", and tells you why in one sentence.
Guardrails built in
Workflows start paused, can run draft-only, and have hard caps per conversation and per day. Every send is logged with its reason.
An inbox that reads for you
AI on every message, so you know what a thread wants before you open it.
A summary on every email
Key points at a glance for every message that lands, newsletters included.
Ask your mail anything
Get answers from across your mailbox, with citations to the emails they came from.
Suggested replies and Verify with AI
Drafts written the way you write, and a check that tells you whether an email looks genuine or suspicious.
Memory of your work
It remembers the facts that matter, like prices, policies and people, and uses them in every reply.
Fits how you already work
Nothing to connect and no password to hand over. Move over one kind of mail at a time.
Your address, or your domain
Start with @uselateron.com, forward mail from your current provider, or send and receive on a domain you own.
Calendar and booking pages
Keep events next to your mail and share a booking link people can pick a time from.
MCP server and API
Let Claude or any MCP client work your mail, calendar and workflows with a single API token.
Installable, with push
Add it to your phone or desktop home screen and get notified the moment a thread needs you.

You get a mailbox at @uselateron.com and you describe the email jobs you want handled — "when someone emails with [enterprise] in the subject, send our pricing and ask how many seats they need". LaterOn watches for those emails, replies in your voice using your instructions and memory, chases the ones worth chasing, and closes the conversation the moment your goal is met. Everything it sends lands in your mailbox, so you can read every word it wrote.
