Watch first: how Coldoutbound.io turns your replies into booked calls automatically.

What Coldoutbound.io fixes

You can't scale outreach, if all of your communication is manual.

You already did the hard part. Someone saw your outreach and showed intent. What happens in the next 5 minutes decides if that becomes a meeting or not.

Interest fades while you wait

The longer a warm reply sits, the less likely the prospect is to book a call or buy.

Positive replies arrive at random

A prospect says “sure, send me more” at 6:40 a.m., in the middle of a sales call, or on a Sunday.

Nobody can respond instantly every time

Founders are selling and delivering. VAs work set hours. The reply waits.

Follow-ups get forgotten

One reply, then silence. Without a second and third nudge, good leads quietly go cold.

Someone has to watch the inbox

Monitoring for replies all day is costly founder time, and creates expensive employee costs.

Qualified conversations slip through

Meetings you already paid to generate never make it onto the calendar.

100×

You are 100 times more likely to make contact with a lead if you respond within 5 minutes versus waiting 30 minutes.

Our experience

We made this after seeing how much cash our own outbound agency was leaking.

“We were sending millions of outbound messages and getting plenty of positive replies. The problem was that many interested prospects never booked because we were not responding quickly enough. Leads were coming in while we were busy, sleeping, or focused on other work.
Once we automated the reply and follow-up process, our positive-reply-to-booking rate moved from roughly 15% to 25% to 30% and, in stronger campaigns, 35%. We generated more meetings without sending more outreach and saved approximately $3,000 per month in VA costs.”

Human-sounding replies only

No AI slop

We trained Coldoutbound.io, our reply agent, on over 11 million emails and 40,000 positive replies over the last 3 years from running our own multi-seven-figure agency and all of our client data. We refined the reply outputs to not include any reply that doesn’t sound like a real human.

Real conversations

See how it handles real conversations.

These are screen recordings from live campaigns run by JKD Agency. Every reply is written from the user’s own instructions and what the prospect actually said, so no two responses are the same.

A simple “sounds good”

The prospect shows interest. The agent replies within minutes, keeps the momentum, and offers the booking link the client chose.

“What do you actually do?”

The agent explains the offer in the client’s own words, keeps it short, and moves the conversation toward a call.

A pricing question

The agent follows the client’s pricing rule: share it, give a range, or explain that pricing is covered on the call.

“Can we just book a time?”

The prospect is ready. The agent skips the back-and-forth and sends them straight to the calendar.

Following up after silence

The prospect went quiet. The agent follows up on the client’s schedule until they book or clearly disengage.

How it works

Live after one call. On autopilot in about a week.

We connect and configure everything with you during your setup call. You review the agent’s replies for 7 days, then let it run automatically to ensure high quality.

Step 01
Connect your outreach platform
Connect Instantly or HeyReach.
Step 02
Customize how the agent replies
Define your tone, offer, qualification rules, pricing behavior, booking rules, and objection handling.
Step 03
Approve replies for 7 days
Start in human approval mode so you can review exactly what the agent recommends.
Step 04
Turn on autopilot
Once the replies look right, let Coldoutbound.io respond, follow up, and book meetings automatically.

What happens when a positive reply lands

Detects the positive reply the moment it arrives
Responds in within 5-10 minutes
Reads the full conversation, not just the last line
Books meetings directly into your calendar
Writes a personalized response from your custom prompt
Follows up until the prospect books or disengages
Handles questions and objections the way you defined
Asks qualifying questions first, or sends everyone straight to booking. Your call.

Two modes

Stay in the loop, or step out of it.

Every account starts with you in control. You decide when the agent is ready to run on its own.

Human approval mode

Start here

Agent drafts the reply
You review, edit, and approve
Best for initial training and confidence

Automatic mode

After 7 days

Agent responds automatically
Works day and night
Best after the first 7 days
No inbox monitoring required

Recommended onboarding: run human approval mode for your first 7 days, edit anything that isn’t right, then switch on automatic sending once the replies match your standard.

The math

More meetings from the outreach you already paid for.

You are already paying for lists, domains, inboxes, and sending tools. Coldoutbound.io improves what happens after the reply, so the extra meetings cost you no extra outreach.

Illustrative example

At 100 positive replies per month:

15% booking rate15 booked calls

30% booking rate30 booked calls

That is 15 additional booked calls without sending another outbound message.

Illustrative only. Your numbers depend on your offer, audience, campaign quality, and reply volume.

Your options

How Coldoutbound.io compares.

A good VA can be genuinely useful. For the repetitive work of watching inboxes and following up, software is simply more consistent.

Criteria	Coldoutbound.io	Replying yourself	Hiring a VA	Doing nothing
Response speed	Under 5 min on email, under 10 min on LinkedIn	Whenever you check your inbox	During their working hours	Replies go unanswered
Availability	24/7, including nights and weekends	Your working hours, minus meetings	Their shift	None
Follow-up consistency	Automatic, until they book or disengage	When you remember	Depends on the process and the person	None
Founder time	Review replies for 7 days, then minimal	Hours every week	Training, managing, and reviewing	None, but meetings are lost
Monthly cost	$499 flat, plus your OpenAI usage	Your time	At least $1,000, but higher the more replies you have	$0, plus the lost meetings
Scalability	More replies at the same flat price	Capped by your time	More volume means more hires	Not applicable

Coldoutbound.io is software, not an outbound agency. It works on the replies your campaigns already produce.

Cold outreach strategy consulting
Lead list building
Campaign copywriting
General outbound consulting
Managing your entire outreach operation
A guaranteed number of booked meetings

You provide your own OpenAI API key. OpenAI bills that usage to you separately. It is typically low, but it depends on your reply volume.

Try Coldoutbound.io risk-free for 7 days. If you are not happy with the quality of the replies, the service, or anything else about the software within your first 7 calendar days, contact us for a full refund. No questions asked.

Fit check

Who it is for, and who it is not for.

Coldoutbound.io works on replies you already get. If there are no replies yet, it has nothing to convert.

Good fit

You send cold email or LinkedIn outreach
You receive at least 10 positive replies per month
You want more booked meetings from the same outreach volume
You or a VA manually handles replies
You want faster response times and automatic follow-up

Not a fit

You are not sending outbound
You receive no positive replies
You want someone to build your complete outbound strategy (JKD Agency helps with that)
You need lead lists or campaign copywriting
You want guaranteed meetings regardless of campaign quality

Who built it

Built by an outbound operator, for outbound operators.

Coldoutbound.io was built by JKD Agency, the outbound company run by Josh Dueck. We have sent or overseen more than 11 million outbound emails and generated more than 40,000 positive replies for ourselves and our clients.

We built the tool because we had the problem ourselves: plenty of interested prospects, not enough speed. It is the same system we use on our own replies, and you get direct access to Josh and our engineer while you set it up.

11M+ outbound emails sent or overseen
40,000+ positive replies generated

FAQ

Questions, answered straight.

Does this replace Instantly or HeyReach?

No. Coldoutbound.io works after those tools generate the initial outreach and the prospect replies positively.

Does it work with LinkedIn?

Yes, through HeyReach.

Does it work with cold email?

Yes, through Instantly. A Smartlead integration is expected in about 2 weeks.

Can I review replies before they send?

Yes. Start in human approval mode. The agent drafts replies and you can edit or approve them.

Can it run automatically?

Yes. After reviewing the agent in approval mode, you can turn on automatic sending.

Can I customize what it says?

Yes. The response behavior is based on your customizable prompt, including tone, offer, qualification, pricing, objections, and booking instructions.

Can it answer pricing questions?

Yes. You decide how pricing questions are handled. The agent can share pricing, redirect to a call, or follow your custom instructions.

Can it qualify leads before booking?

Yes. However, the recommended default is to reduce friction by getting interested prospects onto the calendar quickly and qualifying them after booking when appropriate.

Does it follow up?

Yes. It can follow up with prospects who do not book or stop responding, based on your instructions.

Does it book meetings?

Yes. It can book directly into your calendar.

What does setup look like?

You book a 45-minute call. The first 15 minutes confirm fit and answer final questions. The remaining 30 minutes are used to connect and configure the software live.

What does it cost?

$499 USD/month or $4,500 USD/year. No setup fee. The customer provides their own OpenAI API key.

Is there a guarantee?

Yes. You have 7 calendar days to evaluate the quality of the replies and service. If you are not satisfied for any reason, contact us for a full refund. No questions asked.

What if I need complete outbound consulting?

Coldoutbound.io is software, not a complete outbound consulting service. Separate consulting may be available, but it is not included in this offer.
