Cold email is dead. What works in 2026 for Belgian B2B?
3.4%. That's the average reply rate for B2B cold emails in 2026. A year ago, it was 5.1%. Two years ago, it was 7%. The graph only points in one direction.
If you're reading this, you probably already know. Your outbound sequence sends 200 emails a week and you get three replies, if you're lucky. Two of them are "remove me". The third is a prospect who once spoke to your colleague.
The question is no longer whether cold email works. The question is: what do you do with the time you free up by sending fewer cold emails?
What the numbers say (and don't)
Cold email isn't completely dead. But it only works for one type of company: businesses that can generate volume. 50,000 contacts per month, an infrastructure team for deliverability, their own warming domains. If you're not that, you're in a race you're guaranteed to lose.
The numbers themselves:
- Average B2B cold email reply rate (2026): 3.4%
- Top 10% of campaigns: 8-12%
- Best-in-class (advanced personalization, tight ICP): 15-25%
- Gifting-augmented outbound (US data): 18-26%
Two things stand out. One: the top still achieves reply rates that an average B2B professional will never reach, because the top works fundamentally differently (see below). Two: gifting-augmented sequences achieve comparable numbers with a fraction of the volume.
Why B2B in Belgium is extra difficult
Three Belgian realities that US data doesn't see:
1. The market is small. 50,000 contacts sounds like a lot until you try to scrape them in a country of 11.5 million inhabitants. For an ICP of CRO/Head of Sales at SaaS companies with 50-500 employees in Belgium, you end up with a list of ~600 people. Your entire addressable market fits into one spreadsheet. Mass cold email destroys that market in six months.
2. NL/FR split. A Flemish CEO doesn't open an English email with "Hey {{first_name}}". A Walloon CIO doesn't read a Dutch subject line. Your effective market halves itself.
3. The buyer is wary. Belgian B2B buyers are, on average, less receptive to American-style outreach. No "Quick question" subject lines. No "circling back" follow-ups. No 7-step sequence. It just doesn't work.
This combination means that the cold email model that succeeds in San Francisco flops in Antwerp.
What DOES work: three alternatives, honestly compared
Alternative 1, Referrals
The oldest and best. Reply rate: ~80% (warm intro), conversion to meeting: 40-60%. Problem: you can't scale it. You have 12 referrals per quarter, not 120. For early-stage B2B in Belgium, this is still the #1 channel, but it's a supplement, not a complete outbound strategy.
Alternative 2, Account-based outreach with a physical touch (cake, gift, handwritten card)
This is what made Sendoso and Reachdesk big in the US, and what ColdCake does for Belgium. Reply rate: 18-26% according to Sendoso data, depending on the segment. Conversion to meeting: 30-40%.
It works for three reasons:
- You can delete an email in 2 seconds. You can't ignore a cake on your desk; colleagues see it, ask about it, and the recipient has to respond.
- The reception handles the delivery. Your gatekeeper becomes your amplifier.
- A cake is a conversation-opener with substance. "I saw you just closed Series B, congratulations, here's a cake" reads as sincere. The same text by email reads as robotic.
Cost per touchpoint: €99 to €459 for the cake + shipping included in Antwerp. Compared to cold email (€0.02 per email), that seems absurd. But if your goal is meetings, not open rates, then the math is simple: 100 emails at 3.4% reply = 3.4 replies, of which 0.5 meetings. 5 cakes at 25% reply = 1.25 replies, 0.4 meetings. Per euro, gifting isn't better yet, but per hour of founder time, it's 10× better, and the meetings you get are warmer.
Moreover, in Belgium, it's fiscally smart. A ColdCake with your logo on a handwritten card falls under advertising costs, not business gifts. Advertising costs are 100% deductible; business gifts are 50%. We have worked out the math here.
Alternative 3, LinkedIn paid (sponsored InMail)
Works for some niches, especially senior leadership and enterprise sales. Reply rate: 6-10%, costs €0.80-€2 per send. Requires tight ICP targeting and good copy, otherwise you're just sending expensive cold emails.
The comparison, in one row
| Channel | Reply rate | Cost per touch | Scalability | BE-fit |
|---|---|---|---|---|
| Cold email (regular) | 3.4% | €0.02 | High | Low |
| Cold email (top 10%) | 8-12% | €0.50+ | Medium | Medium |
| Referral | ~80% | €0 | Low | High |
| Gifting-augmented outreach | 18-26% | €99 to €459 | Medium | High |
| LinkedIn paid InMail | 6-10% | €0.80-€2 | High | Medium |
The practical sequence for a Belgian B2B team in 2026
- Maximize referrals. One hour per week asking existing clients for referrals generates more pipeline than five hours of cold emailing. Nobody asks for it.
- Reserve cold email for cold tier 3. Long list, low ICP fit, high volume. Expect 3.4% reply and plan accordingly.
- Invest in gifting for tier 1 (top 20 dream accounts). 20 cakes per quarter, €99 to €459 each. Expect 4-5 meetings.
- LinkedIn paid for tier 2. Mid-quality list of ~200 accounts. Sponsored InMail, not regular connection request spam.
Nothing revolutionary. But most Belgian sales teams still do 80% cold email, 10% LinkedIn, 10% referrals today, and are surprised that their pipeline is declining.
Why this is important for ColdCake
We make the third alternative practical. You choose a cake, write a 150-character card, we personally deliver it to your prospect's office in Antwerp. Three steps. No Sendoso annual contract, no platform license. One cake, one delivery, one conversation that never would have happened otherwise.
Our plans start at €99 for a one-time cake. A Test Kitchen subscription (5 cakes/month) is €549/month, less than most BE B2B teams spend on Sales Navigator.
Cold email isn't dead. But it's dead for 99% of Belgian B2B companies that don't have the volume to combat the 3.4%. For the rest, there's a better option. And it fits on a desk.
