B2B acquisition engines. Deliverability first, then the copy.
Two hundred emails sent to companies that might buy, four replies, and the conclusion is that the copy didn't work. This piece builds the infrastructure that gets the message delivered first, then prepares the sequences, and leaves the sending to a person.
Deliverability comes before copy. Domains separate from your main one, authenticated with SPF, DKIM and DMARC, and volume that ramps up slowly. Without that, the best message in the world never gets read.
The thresholds are public, and they're tight. Google asks senders to keep complaints below 0.10% and never reach 0.30%. Out of a thousand messages, that's three people.
Sending stays in human hands. The system prepares, verifies and queues. No message reaches a buyer until a person has read and approved it.
This page covers a single piece of the system. The other pieces, and how we choose which one to start with, are on the services page.
The problem is that campaigns get judged on the wrong number
Almost every cold campaign is judged on its reply rate, which means nothing without the delivery figure. A campaign with a 2% reply rate where only half the messages were delivered and one with 4% where all of them were are telling the same story, yet they lead to opposite decisions.
When replies don't come, people rewrite the subject line, then the opening paragraph, then the whole message. If the real problem was deliverability, every rewrite burns through more good contacts, because every send from a domain that's already damaged makes its reputation worse instead of proving anything.
A message that never arrives isn't a message nobody replied to. It's a contact burned without anyone knowing.
What changes in practice
You know how many messages were delivered. The first thing that changes is that the reply rate becomes a number you can actually read, and decisions about the copy are based on something people really read.
The second change is that your main domain stays safe. Invoices, orders and confirmations keep reaching your current customers, because cold outreach happens on separate domains and yours is never put at risk.
The third is time. Finding the right contact, verifying the address, personalising line by line and scheduling follow-ups are the jobs that eat up the hours today, and they're also the part a machine can do without getting tired.
The deliverability thresholds are public, and they're tight
Anyone sending more than 5,000 messages a day to Gmail addresses falls under Google's guidelines for bulk senders, which require SPF, DKIM and a published DMARC policy on the sending domain. On complaint rates, the requirement is spelled out: “Keep spam rates reported in Postmaster Tools below 0.10% and avoid ever reaching a spam rate of 0.30% or higher”.
0.30% of a thousand delivered messages is three people hitting the report button. That's why a bought list can wreck a domain in a morning: a handful of annoyed recipients is enough to cross the threshold at any volume.
Yahoo's guidance asks senders to stay below 0.3%, to authenticate with SPF, DKIM and an aligned DMARC policy, and to honour unsubscribes within two days. In their words: “Keep your spam rate below 0.3%”. When two independent providers ask for the same things, it's a requirement, not a suggestion.
Sending domains have to be set up, and it takes time
The work starts weeks before the first message goes out, and it's the part hardly anyone includes in the quote. Every domain has to be bought, authenticated, connected to real mailboxes and ramped up gradually, because a domain that goes from zero to three hundred emails in a day looks exactly like a spammer.
| Step | What happens | What you get |
|---|---|---|
| Separate domainsnot your main one | We register domains close to your company name, used only for cold outreach, and your main domain stays out of it. |
Invoices and confirmations to current customers keep getting through, whatever happens to the campaign. |
| AuthenticationSPF, DKIM, DMARC | Each domain declares who's allowed to send on its behalf and signs its messages, with a published, aligned DMARC policy. |
Messages stop being rejected outright by the big mailbox providers. |
| Gradual ramp-upweeks, not days | Daily volume per mailbox grows a little at a time, with a per-mailbox cap that's never exceeded. |
Reputation gets built instead of burned on the first send. |
| Address verificationbefore sending | Addresses are checked before sending, and any that don't exist are removed from the list instead of bouncing. |
The bounce rate stays low, which is one of the signals reputation depends on. |
| Unsubscribeshonoured straight away | Every message includes a simple way to opt out of further emails, and anyone who uses it is removed from the list within two days. |
Complaints stay below the threshold, because people who want out have an option other than the report button. |
The list matters more than the copy
RAIN Group's research centre surveyed 488 buyers, representing $4.2 billion in purchasing across 25 industries, along with 489 sellers. 82% say they accept meetings with sellers who reach out first, and it takes an average of eight touches to get a meeting.
There are two practical consequences, and the first is uncomfortable. One message isn't an attempt, so the number of follow-ups and the point where you stop are agreed in advance, together, rather than improvised when the reply doesn't come.
The second is that choosing the list matters more than the writing, because eight touches to the wrong person are still eight touches to the wrong person. Researching and verifying contacts is a separate piece: finding and qualifying new leads.
The legal side is a question for your adviser
The rules on unsolicited commercial contact vary depending on who receives it, which country they're in and whether there's an existing relationship. In Italy, the framework for commercial messages is set out in the guidelines of the Garante per la protezione dei dati personali, the Italian data protection authority, and destination countries have rules of their own.
We don't give advice on this, just as we don't on tax. It's a question to take to your own adviser before you start, and the system is built so that whatever you decide can be applied: a record of who was contacted and when, unsubscribes honoured, and permanent exclusion for anyone who asks.
What goes out on its own, and what waits for a person
All the work that doesn't touch a buyer runs on its own: researching contacts, verifying addresses, setting up domains, personalising drafts, scheduling follow-ups and tracking deliverability.
No message goes out on its own. The system prepares and flags, and no message reaches a buyer until a person has read and approved it: here the rule is absolute, because a cold email puts the company's name in front of someone who doesn't know you. The full reasoning is on our page about the principles we build by.
Same mechanism, different name in every trade
The mechanism is identical; who you're reaching out to isn't. It's worth looking at your own case, because that's where you see who to go after, and with which document in hand.
| Sector | Who gets contacted | Where you see it |
|---|---|---|
| Food and agricultureand export | Importers and distributors in a specific country, approached with the spec sheet and price list already prepared in their language. |
|
| Hospitalityaccommodation and events | Foreign agencies and organisers who bring groups, approached out of season with the dates still available and room capacities. |
|
| Restaurantsand bars | Local companies and organisations for business lunches and events, where the buyer is someone organising on behalf of others. |
What this piece doesn't do
It doesn't promise a reply rate, and it doesn't publish one. The figures going around on this topic come from campaigns, markets and lists that have nothing to do with your case, and any forecast built on them would be made-up numbers dressed up as data.
It doesn't buy lists. A bought list is full of dead addresses and people who've never heard of you, and it's the fastest way to cross the complaint threshold described above.
It doesn't write the material needed to follow up. When someone replies asking for a spec sheet, price list or quote, that document needs to exist already: that's handled by sales copy and materials.
Questions and answers
Why do cold emails end up in spam?
Almost always for a technical reason settled before the copy is even written. Google's guidelines for bulk senders require SPF, DKIM and DMARC on the domain, and a complaint rate kept below 0.10% that never reaches 0.30%. Yahoo's guidance asks senders to stay below 0.3% and to honour unsubscribes within two days.
A new, unauthenticated domain that starts sending at high volume gets treated accordingly, and at that point the copy doesn't matter, because nobody reads it.
Can we send from the company's own domain?
We advise against it, and the reason is reputation. The domain your invoices, orders and customer confirmations come from is the one that can't afford any risk, because if its reputation drops, it's the important messages that stop getting through.
Cold outreach goes out from separate domains, similar to yours and authenticated one by one, which ramp up volume gradually. Your main domain stays out of it entirely.
How many touches does it take to get a reply?
According to research by RAIN Group's research centre, covering 488 buyers, 82% accept meetings with sellers who reach out first, and it takes eight touches on average to get a meeting. The buyers are mostly in the US, across 25 industries, so treat it as an order of magnitude, not a promise.
The practical upshot is that one message isn't an attempt, and the number of attempts should be agreed in advance, along with the point at which you stop.
Do messages go out on their own?
No, and for this piece the rule is absolute. The system prepares the sequences, personalises them using verified data and queues them, but no message reaches a buyer until a person has read and approved it.
A cold email puts the company's name in front of someone who doesn't know you, so it's one of the things that never goes out automatically, along with quotes, prices and confirmations.
How do you measure whether it's working?
By qualified meetings booked, which is the agreed metric, but before that you look at deliverability. If you don't know how many messages were actually delivered, the reply rate means nothing: a campaign with a 2% reply rate where only half the messages were delivered and one with 4% where all of them were are telling you the same thing.
So you measure, in this order: messages delivered, complaints received, replies, and only then meetings booked.
Notes on sources
- The 5,000-messages-a-day threshold, the SPF, DKIM and DMARC requirements and the complaint rates come from Google's guidelines for bulk senders, quoted word for word. They apply to Gmail inboxes, not to every recipient: they're the rules of the most widely used mailbox provider, not the law.
- The 0.3% threshold, the authentication requirements and the two-day deadline for honouring unsubscribes come from Yahoo's guidance for senders. They apply to that provider's inboxes, and we cite them because they match Google's: when two independent providers ask for the same things, those things stop being a matter of opinion.
- The 82% and the eight touches come from research by RAIN Group's research centre, covering 488 buyers representing $4.2 billion in purchasing across 25 industries, plus 489 sellers. RAIN Group sells sales training, so it has a stake in the result, and the sample is mostly US-based and not from the food sector: the original wording says buyers accept meetings, not that they reply to every message.
- The reference for Italian rules on commercial messages is the guidelines of the Garante per la protezione dei dati personali. This page isn't legal advice: cold outreach to a foreign company depends on the country and any existing relationship, and it's a question to take to your own adviser before you start.
- We don't publish any expected reply rate. The figures going around on this topic come from different markets, lists and offers, and using them as a forecast for your case would be made-up numbers dressed up as data. The first number to measure is deliverability, which is in your hands.
- This page doesn't report results achieved for a client, because this piece hasn't yet been delivered to a client. The tests mentioned are functional checks run in a test environment.

If you've already sent cold emails, there's only one useful question: how many were actually delivered? If the answer is that nobody knows, the reply rate you have in mind doesn't measure anything. In fifteen minutes on the phone we'll look at it together and tell you where it makes sense to start, even if we never end up working together.
You'll speak to Mattia Esposito, who then builds the system: there's no salesperson in between. If you'd rather measure things yourself before talking, the Diagnostico (in Italian) is twenty questions and five minutes.
