Every year, the GDMA Email Benchmark gives us a rare look across borders: billions of emails, thirty-plus countries, one shared dataset. As contributors, we get to spot the patterns that don’t make it into the headlines.
Sweden accounts for just 0.5% of European email volume, but turns out to be one of the most interesting email markets on the continent. Not because it’s the biggest, but because of how it performs. Here’s what the numbers say.
Insight 1: Swedes open almost everything
Let’s start with the metric that jumps off the page. The global average unique open rate (OR) sits at 34.15%. Sweden? 42.27%. That’s roughly 24% above the global benchmark, and the highest open rate of any sizable European market apart from the Netherlands (which leads the continent at 48.9%).
To put it in perspective: for every 100 emails landing in a Swedish inbox, more than 42 get opened. In most of the rest of the world, that number is closer to 34.
Why does this matter?
Open rates have become a fuzzy metric since Apple’s Mail Privacy Protection kicked in back in 2021, but the directional signal is still useful, especially when you compare like-for-like across countries. A consistently high OR points to strong sender reputation, sharp subject lines, and (most importantly) audiences that want the email.
Insight 2: The cleanest lists in Europe
If open rates tell you about engagement, acceptance rates tell you about discipline. How many of your emails hit the inbox depends on a long list of criteria, and therefore, commitment to get them there.
| Metric | Sweden | Global average |
| Hard Bounce Rate | 0.32% | 0.6% |
| Soft Bounce Rate | 0.34% | 0.8% |
| Acceptance Rate | 99.3% | 98.6% |
That’s not a marginal difference. Sweden’s hard and soft bounce rates are roughly half the global average. Almost every Swedish email gets accepted by the receiving server.
What is a bounce rate?
A hard bounce is a permanent delivery failure. A soft bounce is temporary and can be caused by a full inbox or a server issue, for example. Both eat away at your sender reputation if left unchecked. Low bounce rates mean someone is taking list hygiene seriously: regular cleaning, double opt-ins, and a hard line on inactive addresses.
Insight 3: Big sends, frequent sends, and no apparent damage
This finding is a bit counterintuitive. Conventional email marketing wisdom says: send more, and engagement drops. Send bigger, and relevance suffers. Sweden seems to be breaking both rules at once.
- Average campaign size: 41,506 recipients (vs European average of 28,102, about 48% larger)
- Average campaigns per sender: 468 (vs European average of 340, 38% more)
Swedish senders are reaching larger audiences more often and achieving better open rates than nearly everyone else. That’s not supposed to happen. The usual story is that frequency and reach erode engagement over time.
Unless, of course, the underlying list and content quality are high enough to support it. Which brings us neatly back to insight 2.
Insight 4: The open-to-click gap
For all that engagement at the top of the funnel, Sweden’s click-through rate (CTR) is 3.0%, almost exactly the global average of 2.99%. The click-to-open rate (CTO) is 8.03%, only fractionally above the global average of 7.73%.
In other words, Swedes open emails enthusiastically, then click at a rate that’s right in the middle.
Why does this matter?
Compare that to fellow Europeans like the Netherlands (CTR 6.2%) or the UK (CTR 4.4%), and a gap appears. Swedish marketers are getting the email opened. The follow-through, however, is still up in the air.
This is genuinely useful intelligence. It tells you that if you’re marketing into Sweden, the limiting factor isn’t deliverability or attention capture: it’s what happens after the open. Content relevance, CTA placement, and offer-market fit. The unsexy bits are where the actual conversion lives.
Insight 5: Trust, by the numbers
Last one. The spam complaint rate (SCR) in Sweden is around 0.005%, half the global average of 0.01%. That’s well below the 0.3% threshold that Google and Yahoo now enforce, and well below any level that would cause deliverability concerns.
Why does this matter?
Spam complaint rate is the closest thing email has to a trust metric. It’s the rate at which your audience actively says, “I didn’t want this, and I’m telling my inbox provider.” When it’s this low, it means recipients see the sender, recognise the brand, and don’t feel ambushed.
So, what’s the lesson here?
Sweden isn’t winning because of some Nordic email marketing secret. It’s winning because the fundamentals are in place: clean lists, audiences that recognise the sender, sensible frequency, and content that’s relevant enough not to trigger the spam button.
For the rest of us, the message is two-fold:
- The basics still beat the tactics. No clever subject line will outperform a properly maintained list. Sweden’s data is a reminder that hygiene and trust compound over time.
- Know which battle you’re fighting. If your open rates are healthy but clicks lag, don’t keep optimising the subject line. Look downstream: at the offer, layout, CTA, and the content’s relevance to the segment.
The Swedish playbook isn’t really a Swedish playbook. It’s just the email marketing playbook, executed consistently, by a market that took it seriously a long time ago.
