The problem

Cold email today is six tools and one tired person.

The stack you run by hand

  • List toolyou pick the leads
  • Sequenceryou write every step
  • Warmup toolyou watch the health
  • Copywriteryou, at 23:40
  • Repliesyou, between meetings
  • Calendaryou chase the time
Nothing talks to anything Every reply waits for you

One agent

  • Finds the buyers
  • Writes each email from scratch
  • Warms and paces the inboxes
  • Answers every reply in minutes
  • Books the meeting
One inbox to check Five minutes a day
One agent, three jobs

It hunts. It answers. It remembers.

Cold outreach is the opening move. The agent runs your whole email desk: new people, everyone who writes in, and the customers you already have.

Agent → Tom Becker, Head of Ops

Tom — saw Northwind opened a Rotterdam hub last month. Ops leads usually hit the 'who chases the carriers' problem right about now. Two peers solved it without a hire; 12 minutes to show you?

Scale by stacking inboxes, never by blasting.

Every inbox warms up on its own and holds to about 50 sends a day once warmed, the pace that keeps domains healthy. Need more? Add inboxes, not risk.

  • Automatic warmup: 5/day → 50/day in about two weeks
  • Randomized, human-paced sending across every inbox
  • Opt-outs honored instantly, real threads — never mail-merge
  • Gmail, Outlook, IMAP, or a managed inbox we provision

No Setup Screens

Run the whole thing from one conversation

Mr. Sellinger is your AI sales director. Tell him who you sell to and he sets the agent up, shows you the first drafts, and briefs you every morning — no forms, no training, no ops team.

Mr.Sellinger

Online • 100+ tools available

Ask Mr.Sellinger anything...

Set up by talking

“Sell my analytics tool to fintech COOs in the UK” is the whole setup. He picks the segment, drafts the persona, and shows you the first message before anything sends.

Change anything mid-flight

“Be less formal.” “Stop contacting Acme.” “Offer Thursdays only.” Every instruction lands on the live agent in seconds.

A briefing every morning

Replies that need you, meetings booked overnight, what he decided and why — in the app, on WhatsApp, or on a call.

How it works

Set up tonight. Sending tomorrow.

Fifteen minutes of setup, then about five minutes a day. No copywriting, no sequences, no ops.

  1. Connect an inbox

    Gmail or Outlook in one click, IMAP for anything else, or a managed inbox we provision. Warmup starts immediately.

  2. It reads your business

    Point it at your website. The agent reads it, learns what you sell, who buys and how you talk, and writes the first email.

  3. Approve the first drafts

    Review the first batch in the morning briefing. Fix the tone once; it remembers.

  4. Show up to the meetings

    It sends, answers within minutes, follows the quiet ones to WhatsApp or LinkedIn, and books into your calendar.

The honest part

We know. One more tool is the last thing you want.

Learning a new platform while running a business is overwhelming; we hear it on every call. So this one needs almost nothing from you: no sequences to write, no setup screens, no training. Type your website, connect an inbox, say yes to the first drafts. That's the whole onboarding.

What we see from the inside: the firms that waited on AI didn't lose to better products. They lost the reply, to whoever answered first, at 23:40, in the buyer's language, with the meeting link already in the message. The gap isn't the tool. It's the hour.

Everything you'll actually do

  • 1

    Type your website

    Right here, on this page. The agent reads it and shows you what it understood — you saw it above.

  • 2

    Connect an inbox

    Gmail or Outlook, one click. Warmup starts on its own.

  • 3

    Say yes to the first drafts

    Tomorrow morning, in your briefing. Fix the tone once; it remembers.

Then it runs. About five minutes of your attention a day — and nothing is ever sent without your OK until you say otherwise.

FAQ

Straight answers about AI cold email.

How is this different from Instantly or Smartlead?
Those are sending infrastructure: you write the sequences, they deliver them. Sellinger is the salesperson: it researches each lead, writes each email from scratch, answers the replies, handles objections, and books the meeting. And when email goes quiet, it continues the same conversation on WhatsApp or LinkedIn — something an email-only tool can't do.
Will my emails land in spam?
Honest answer: no tool can guarantee inbox placement. What we can guarantee is discipline — automatic warmup, per-inbox daily limits, randomized human pacing, real threads, and instant opt-out suppression. Deliverability problems almost always come from volume abuse, and the agent is built to refuse it: slow and steady is the whole strategy.
How much volume can I actually send?
One warmed inbox sends up to about 50 emails a day. Plans are sized by messages and inboxes: Starter is 1,000 messages on 1 inbox, Growth 4,000 on 3, Scale 12,000 on 8. You scale by adding inboxes, so no single domain takes on risky volume.
Does it only send, or does it handle what comes in too?
Both. Anyone who emails you — a reply, a new enquiry, an existing customer with a question — gets an answer in minutes from your real knowledge base, becomes a lead in the CRM, and gets followed up. For most teams the inbound side is what frees up the first hours.
Do I need to write anything?
No. You point the agent at your website and docs, tell it who you sell to and what a good meeting looks like, and it composes everything itself. You can review every draft before it sends, or let it run fully autonomous — your choice, per campaign.
What happens when someone replies?
The agent answers within minutes, in the same thread, with full context. If a reply needs a human — pricing negotiation, an angry prospect, a request to speak to a person — it flags the lead for you and steps aside for that conversation only.
Can I use my existing email address?
Yes. Connect Gmail or Outlook in one click, any other inbox via IMAP, or let Sellinger provision a managed sending inbox for you. Your domain, your name, your sent folder.

See it on your business. 60 seconds.
