I run outbound for B2B companies at Sales Boutique, and for Contaktly, the software I co-founded. This is the setup we use in 2026. The list and the message change from client to client; the setup doesn’t.
What to Expect Before You Start
Cold email is a numbers game with small numbers. In October 2026 (to 27 October) our net-new cold campaigns sent 49,834 emails to 28,782 people and got 1.1 replies per 100 emails, or a 1.9% reply rate per person contacted. 15% of the replies were positive. The rest were “not interested”, “wrong person”, “remove me” and out-of-office auto replies.
That’s across dozens of campaigns in different industries, so your campaign will land above or below it. The live number is on the cold email benchmark, refreshed monthly.
If someone promises you a 10% reply rate on cold email in 2026, ask to see their Smartlead screen.
1. One Buyer, One Problem
Pick one job title and one problem you solve for them. “Heads of marketing at design agencies with 10 to 200 staff in the Nordics” is a campaign. “Marketing leaders” is a wish.
Every campaign we run has a name that says who, where and how big. If you can’t write that line, you’re not ready to build the list.
2. The List
The list decides more than the copy does. Our rules:
- Build from a people database with a waterfall of email finders behind it (we use Blitz). A scraped CSV someone sells you is where bounces come from.
- Verify every address before upload. Bounces are the fastest way to burn a sending domain, and the domain is shared by everything else you send.
- Keep campaigns big enough to read. A few hundred people gives you a result you can trust; a few thousand means you can’t personalise.
- Exclude customers, open deals, partners and anyone who has asked to be left alone. One global do-not-contact list across every campaign, applied the same day.
3. Sending Infrastructure
Never send cold email from your main domain. Buy lookalike domains, set up SPF, DKIM and DMARC on each, and create several mailboxes per domain.
Warm them up before the first real email, then keep the daily volume per mailbox low and spread the campaign across the mailboxes. Volume comes from adding mailboxes.
Turn open tracking off. The pixel hurts deliverability and the opens it reports are mostly security scanners. We don’t publish open rates for exactly that reason.
Run an inbox placement test on every new domain before launch and again whenever replies dip. We use MailReach for this.
4. The Message
One email, one ask, plain text. Written as a person: the founder or the account owner.
The angles that work for us, from our own 2025 and 2026 campaigns (the detail is on the results page):
- A founder asking a fellow leader for a coffee. Two to four lines, no pitch, usually with a local hook. Across 18 clients it booked 2.9 times the meetings per person of everything else those clients sent.
- A specific observation about their business. Our best one got a reply from 14% of the people it went to.
- A seat at an event you host. In 2026, event invites booked more meetings per person than any other style we ran.
- Say what happens next, in one line.
And one that didn’t: offering our take on who their next dream client should be. It got fewer replies and fewer positive replies per person than plain cold email.
Whatever works will wear out. Re-sent to the next slice of the same market, our winners fell to a fraction of their first result. Have the next angle ready before you need it.
Three steps over about two weeks. Follow-ups go as replies in the same thread with no new subject line, and each one adds something. “Just bumping this” adds nothing.
Test one thing at a time: image vs no image, Dutch vs English, two different value propositions. Half the list each, same week, and let the numbers decide.
5. Out-Of-Office Is a List, Not a Dead End
Auto replies are between a tenth and a quarter of all the replies we get in a month. Every out-of-office goes into a separate re-send sequence that waits for the return date and emails again.
Our out-of-office re-sends got a 10.7% reply rate, against about 2% for the original cold email. People who’ve just come back to a full inbox are oddly receptive.
6. Reply Handling Is Where the Meetings Are
Most companies lose the meeting after the reply. Our rules:
- Reply fast, in the prospect’s time zone. Our median is 22 minutes; the same working day is the minimum.
- Offer two real times, a morning and an afternoon, two or three working days out. Never “when suits you?”, and never a booking link in the first reply.
- “Any time works” is a yes. Pick a slot, send the invite, confirm it.
- If they go quiet after a positive reply, follow up twice more by email, then move to LinkedIn, then to the phone. Email, LinkedIn, call, in that order, and one channel at a time.
- Someone asking where you got their data gets removed the same day. No argument, no reply.
7. Measure the Right Things
Weekly, per campaign:
- People contacted, replies, reply rate per person
- Positive share of replies
- Meetings booked and meetings held
- Bounce rate
Replies well under the benchmark after a few hundred sends: change the list. Replies but no positives: change the ask. Positives but no meetings: fix your reply handling. Bounces climbing: stop and re-verify.
What It Costs in Time
The design phase (domains, warm-up, list, copy, first sequence) takes us three to four weeks. After launch it’s about an hour a day on replies and a weekly review of the numbers. The tools are on the stack page.
