What is a managed cold email agency?

A managed cold email agency runs your one to one outbound email for you, which is different from marketing email blasts. We set up and warm the sending domains and inboxes, build and verify the lead list, write and test the sequences, and report the results. You bring the offer and reply to interested prospects. Quantum programs start at $3,995 a month.

Is cold email the same as email marketing?

No. Cold email is outbound one to one email: a real person writes to one specific buyer about a specific problem, and a real person answers the reply. Email marketing is a broadcast to a subscriber list. Quantum runs the first kind, never blasts.

Marketing email blastsQuantum one to one outbound
Who it is forA broad list of subscribersA defined set of ideal buyers
The messageOne design sent to everyoneShort plain text written to one person and their role

That is why the page talks about inboxes, domains, and per inbox limits instead of open rates and newsletters.

Four stages from blank slate to booked meetings

Cold email works when the sending infrastructure, the list, and the message are all in good shape. We own all three.

Infrastructure

Sending domains and inboxes sized to your volume, with DNS and authentication configured correctly.

Warm-up

Every inbox builds sending reputation before a single campaign goes out.

Campaigns

Targeted, verified lists and short one to one sequences written for your offer and your buyer.

Testing and reporting

Subject lines and copy tested against each other every month, with a monthly report on sends, replies, and meetings.

How many cold emails can you send per day?

A common planning figure is about 20 emails per inbox per day and 100 per domain per day. At 50,000 emails a month, that is about 2,273 emails per sending day, 114 inboxes, and 23 domains. Mailbox providers set the real limits, so read Google's email sender guidelines. We build and maintain all of the infrastructure.

Cold email ROI calculator: size a campaign

Set how many new contacts you want to reach each month. The calculator works out sending volume, inboxes, domains, and the replies and meetings you can expect at benchmark rates. Add your deal size, show rate, close rate, and sales cycle to see the revenue it could produce.

Worked example with the default inputs: 15,000 new contacts per month, 3 emails per sequence, the benchmark reply and meeting rates, and the best fit plan billed monthly.

Estimates only. Reply and meeting rates vary by industry, offer, list quality, and copy, and the benchmark rates are planning assumptions, not guarantees. Revenue uses the figures you enter. Each deal is up-front only, recurring only, or both, in the shares you enter. Up-front revenue is counted in the month a deal closes. Recurring revenue and additional project revenue are counted evenly across each customer's months, up to the length you enter, within the months shown. Deals close after the sales cycle, spread across the two months it falls between. Inbox and domain counts assume 20 emails per inbox per day and 100 emails per domain per day.

What does it cost to book a meeting?

The honest answer depends on your numbers, so the calculator above works it out from yours. Here is the high level version.

The formula

Cost per meeting equals your total monthly program cost divided by the meetings it books.

An example

At 100,000 emails a month and 1 meeting per 2,000 emails, you book about 50.0 meetings. On the Quantum Growth plan at $5,995 a month, that is about $120 per meeting*. Paid annually at $59,995 a year, it drops to about $100 per meeting.

*Monthly plans have a six month minimum.

What moves it

Reply and meeting rates, sending volume, whether we provide the contacts ($0.50 each), and how much of the work you do yourself.

Cold email agency FAQ

What is a cold email agency?

A cold email agency runs outbound email for a business. It sets up and warms the sending domains and inboxes, builds and verifies lead lists, writes and tests sequences, and reports results. The client supplies the offer and replies to interested prospects.

How much does a cold email agency cost?

Quantum plans cost $3,995, $4,995, $5,995 per month, depending on whether you send up to 25,000, 50,000, or 100,000 emails a month. Monthly plans have a six month minimum and there is no setup fee. Annual plans are paid up front at a lower price. Above 100,000 emails a month, each additional 25,000 emails adds $1,000 a month, or $10,000 a year. Pay per meeting costs $1,000 per guaranteed meeting, paid up front.

How many cold emails can you send per day per domain?

A common planning figure is about 100 emails per domain per day, spread across inboxes that each send about 20 a day. At 50,000 emails a month that is about 2,273 emails per sending day, 114 inboxes, and 23 domains. Read Google's sender guidelines.

Who replies to prospects?

You do. Every plan includes access to the inbox, so your team reads and answers each response and books the meetings. We do not handle replies.

How large does my target market need to be?

A larger market lets us send fewer emails per contact and test more variations. Smaller markets work too, with tighter targeting and more personalized copy. Tell us how many companies and contacts fit your ideal customer profile and we will size the campaign to that.

Is there a contract?

Monthly plans have a six month minimum and there is no setup fee. Annual plans are paid up front for the year at a lower price. Pay per meeting is prepaid.

How does pay per meeting work?

You pay $1,000 per meeting up front and the meetings are guaranteed. You do not manage sending volume. The terms of the guarantee are set out in your agreement. Compare pay per meeting with retainers and hybrid models.

Do you provide the lead lists?

Yes. If you need us to provide contacts, data is $0.50 per contact. You can also supply your own list. Email validation is $0.10 per contact.

What does it cost to book a meeting?

It depends on your reply and meeting rates and the plan you choose. The calculator on this page works it out from your numbers, and the cost per meeting appears in the results. Read the full guide to cost per meeting.

What is the difference between cold email and email marketing?

Email marketing broadcasts one message to a subscriber list. Cold email is outbound and one to one: a short message written to a specific buyer, sent from an individual inbox in small daily volumes, and answered by a person. Quantum runs one to one outbound, not blasts.

Will cold email hurt my company's domain reputation?

Volume is spread across dedicated sending domains and inboxes with a small daily limit per inbox, and every inbox is warmed before it sends campaign email. That keeps the sending reputation of each address in good shape.

Is cold email better than hiring an SDR?

They solve different problems. A salaried SDR costs more per month and works several channels. Managed cold email is a lower fixed cost for one channel, with the volume built in. Many teams run both. Compare the cost of outsourced SDR models.

Do cold emails work?

They can, when the sending setup, the list, and the offer are all in good shape. The benchmark in the calculator, 1 meeting per 2,000 emails, is a planning assumption and not a promise. Your results depend on your market and your message.

Is cold email legal?

In the United States, business cold email is allowed under the CAN-SPAM Act when it has accurate sender details, a physical address, and a working unsubscribe option. Rules differ in other countries, so confirm the requirements for each market you email.

Why does a campaign need so many inboxes and domains?

Each inbox can send only a limited number of emails per day without hurting deliverability. More volume means more inboxes, spread across more domains, so that no single address carries too much.

How soon do campaigns start sending?

New inboxes need a warm-up period before they send campaign email. We confirm the launch date when we scope your program.

Are the reply and meeting rates in the calculator guaranteed?

No. The benchmark rates are conservative planning assumptions, and actual results depend on your industry, offer, list quality, and copy. Change the reply and meeting rates in the calculator to model your own numbers. Pay per meeting is the option that guarantees meetings.
