The numbers, roughly
| Cold email | ||
|---|---|---|
| Typical reply rate | 28.8% text first touch, 40.4% video first touch (our data) | 1 to 3% |
| Realistic daily volume per identity | 15 to 25 connection requests, 50 to 80 messages | Hundreds to thousands |
| Setup cost | Account plus tool | Domains, mailboxes, warm-up, tool |
| Time to first send | Same day | Two to four weeks after domain warm-up |
| Main failure mode | Account restriction | Landing in spam |
| Data required | A profile URL | A verified email address |
| Compliance in the EU | Platform terms | GDPR and ePrivacy, varies by country |
Those reply rate figures are the crux. Email’s advantage is that 1 to 3 percent of a very large number is still a lot of conversations. LinkedIn’s advantage is that you can work a list of 300 well-chosen people and expect real engagement from it.
When email is the right primary channel
Your addressable market runs to thousands of companies. Your deal size is small enough that you need volume to make the maths work. Your buyer is not active on LinkedIn, which is true in plenty of sectors, particularly parts of manufacturing, trades and public sector. You already have verified email data. Or you need to reach several people at one account simultaneously.
When LinkedIn is the right primary channel
Your market is a few hundred companies, not thousands. Your deal is worth enough that a personal approach pays for itself. Your buyer is demonstrably active on the platform, which is most sales, marketing, tech, finance and recruitment leadership. You are selling something that needs a human to open the conversation, which covers most services and mid-ticket software. Or you have no email data and getting it is another cost.
The case for both
The strongest sequences use both, but not simultaneously and not with the same message. A pattern that works:
- LinkedIn connection request with a specific note
- On accept, a voice note within 24 hours
- Day 4, a LinkedIn text follow-up that adds something
- Day 8, an email that references the LinkedIn thread rather than starting fresh
- Day 15, a short video or a final LinkedIn message
The email step lifts overall reply rates without adding LinkedIn volume, which matters because LinkedIn volume is the constrained resource and the limits are real.
The mistake to avoid is sending both channels the same message on the same day. It reads as automation, because it is.
Compliance, briefly and without pretending to be a lawyer
In the EU, B2B cold email generally relies on legitimate interest, which requires that your message is relevant to the person’s professional role, that you identify yourself clearly, and that opting out is easy. Ireland and Germany apply this more strictly than others. Consent rules differ for individual traders and sole proprietors, who often count as consumers.
LinkedIn sits outside that framework because you are using a platform where the person chose to be publicly contactable, though you are bound by LinkedIn’s own terms instead.
Neither of those paragraphs is legal advice. If you are running significant volume into the EU, get someone qualified to look at it once.
The honest summary
Email is a volume channel that has got harder every year as inboxes filter more aggressively. LinkedIn is a quality channel that is constrained by design and getting noisier. The teams doing well in 2026 are not choosing between them, they are using LinkedIn for the accounts that matter and email for coverage, and they have stopped sending the same generic message down both.
