LinkedIn is an indispensable tool for email outreach. Its biggest strength is self-reported data: people tell you where they work and what they do.
Even though you technically don't need to even know LinkedIn exists to send cold emails, it's hard to imagine cold email without LinkedIn. Some outreach tools rely on LinkedIn alone for their B2B data. It's their only source of data on B2B contacts (Hunter is not in that category).
In the best case, you reach out to an exec who has a detailed profile and posts regularly. You can use what's there to understand their pain points, where their company is heading, and what they care about right now.
We checked 488 US execs to see how often that best case actually happens.
Key findings:
- Few execs post anything useful. Only 22% posted something you could use in a cold email in the last 30 days.
- 15% of exec profiles looked fake. At companies with over 1,000 employees, it was closer to 1 in 5.
- Even real profiles are often empty. 24% of real execs wrote nothing about themselves or their role.
Few execs post anything useful
Posts are where the best material lives: an exec's take on their industry, a conference they're speaking at, or a launch they're proud of. You can use this to tie your offer to what the buyer cares about.
But most execs barely post. Of the 347 real execs, over the last 90 days:
- 49% posted nothing at all, not even a reshare.
- 44% wrote at least one post of their own.
- 22% wrote 3 or more.
About a third of all posts were reshares of someone else's content.
Of the posts execs wrote themselves, 62% gave you something you could use in a cold email: an opinion, an event, or company news. The rest were awards, congratulations, or personal causes.
Here's what a good one looks like. One CMO posted about why companies' AI projects stall before production, blaming data plumbing rather than the models. If you sell data infrastructure, that's a specific opinion you can open with, but only for a few weeks.
Usable post no older than | Share of execs |
|---|---|
7 days | 6% |
30 days | 22% |
90 days | 37% |
If you send a campaign today and only reference posts from the past week, about 1 in 17 execs gives you something to work with. And 63% give you nothing usable in three months.
This is also a quality issue. Forced to use old datapoints, your emails won't look genuine.
Even real profiles are often empty
Posts aside, many profiles say very little. Of the 347 real execs, 24% wrote nothing at all, with no About section and no description of their current role. Looking at each part separately:
- 35% have no About section.
- 47% don't describe their current role.
- Only 27% describe their current role in specific terms, like what they lead or what they've achieved.
Take one regional CFO at one of the world's largest automakers. They had over 2,000 followers and 20 jobs listed, but no About section, no role description, and no posts in 90 days. A real, senior, well-connected exec, and nothing to personalize with.
When execs did write something, it was often a bio, not information you can sell with.
What they mention | Share |
|---|---|
A personal detail (school, sport, hometown) | 40% |
A current priority or initiative | 25% |
Results with numbers | 23% |
Tools they use | 14% |
Team size | 8% |
Budget | 6% |
A typical About section reads like "Seasoned finance leader with 20 years of experience driving growth." Doesn't tell you much beyond what the job title already told you.
Many exec profiles are fake
Anyone can type "CEO at GEICO" into a LinkedIn headline, and plenty of people do.
Out of 488 profiles, 72 (15%) looked fake. We flagged a profile as fake when it had fewer than 50 connections or followers and at most one dated job in its history. These are vanity accounts, abandoned test profiles, and jokes, and they all claim a C-level title.
One profile we found had the headline "CEO at GEICO", 1 follower, a single job in its history, and nothing else. When you look at a profile yourself, a fake like this is obvious. But a tool or AI agent pulling titles in bulk won't notice, and will happily write an email to "the CEO of GEICO."
The bigger the company, the more fakes.
Company size | Fake profiles |
|---|---|
11–200 employees | 4% |
201–1,000 employees | 9% |
1,001–10,000 employees | 26% |
10,000+ employees | 18% |
CEO titles were the most faked. 38% of profiles claiming to be a CEO or founder looked fake.
So a title on LinkedIn is only as trustworthy as the profile behind it. If you target big companies and take titles at face value, about 1 in 5 of your "execs" won't be real.
Where LinkedIn works best, and where it doesn't
Some execs are much better LinkedIn targets than others.
Role | Usable post in last 30 days | Profile looked fake | Wrote nothing | Describes role specifically |
|---|---|---|---|---|
Marketing and sales chiefs | 30% | 3% | 20% | 70% |
CEOs and founders | 27% | 38% | 32% | 54% |
Tech chiefs | 22% | 10% | 18% | 57% |
Operations chiefs | 19% | 15% | 24% | 59% |
HR chiefs | 19% | 0% | 19% | 62% |
CFOs | 17% | 7% | 32% | 41% |
Marketing and sales chiefs are the best fit. They post the most, describe their work in the most detail, and almost none of their profiles looked fake.
CFOs are the worst fit. They post the least, a third wrote nothing at all, and only 41% describe their role in specific terms.
CEOs are the trap. They post fairly often, but 38% of profiles claiming a CEO or founder title looked fake, so check the profile before you trust the title.
What this means for your outreach
Building your list
1. You need a way to find active profiles automatically. A LinkedIn URL tells you nothing about whether anyone is behind it. To separate active profiles from empty or fake ones, you need more data per person: when they last posted, how often, and how many followers they have. A list of names and LinkedIn URLs won't give you that.
Using LinkedIn as a channel
2. LinkedIn may be a weak channel if your list doesn't come from LinkedIn. In multichannel campaigns, LinkedIn is often the second touchpoint after email. But if your list comes from a contact database, half the execs on it haven't posted in three months, and some aren't real. An exec who never posts may not log in often either, so your connection request or message can sit unseen for weeks, long after your email sequence has ended. LinkedIn works better as a channel when you build the list from active profiles in the first place.
Personalizing your emails
3. If you use LinkedIn for personalization, pair the exec's profile with their company's page. When the exec doesn't post, the company page often does: launches, hires, and news. Together they let you reference both what the person thinks and what the company is doing.
4. The rest of the web matters more than LinkedIn for personalization. When most exec profiles are empty, LinkedIn can't carry your personalization. And even good hooks often aren't unique to LinkedIn: 60% of the company news execs posted was also on the company website, in a press release, or in the news. Company websites, newsrooms, hiring pages, and tech stack changes give you most of the same material, for every company on your list.
5. If AI writes your emails, give it rules. An AI tool reading a LinkedIn profile will always find something to say, even when there's nothing worth saying. It might reference a two-month-old post as news, or turn a generic bio into a fake compliment. Set limits: only reference posts from the last couple of weeks, and fall back to company news when there's nothing recent.
What to do instead
Treat LinkedIn as one data source, not the source. Verify who you email, personalize from company news and hiring, and save LinkedIn research for the execs who actually post, mostly marketing and sales leaders.
How Hunter helps
Hunter can't make execs post more, but it can help you avoid wasting outreach on fake or outdated contacts.
- Verify emails before you send. Contacts with a Valid email were real execs 88% of the time, compared with 55% for Accept all.
- Personalize with company data. Use Hunter's enrichment and Discover to get company details and industry for every company on your list, not just the 22% whose execs post.
How we researched this
To learn how useful LinkedIn is for email outreach, we built a list of 488 US executives with Hunter: CEOs, CFOs, COOs, CMOs, CTOs, and heads of HR, at companies from 11 to over 10,000 employees.
Then we opened each person's LinkedIn. We recorded their headline, About section, and follower and connection counts, plus every role in their job history with titles, dates, and descriptions. We also read their posts from the last 90 days, noting what they wrote about and whether a post gave you something specific to mention in a cold email.
Finally, we checked whether each person still held the job we had on file, and whether their profile looked real.
A few limits are worth knowing. Whether a post was usable was judged by AI against a fixed set of rules, so treat those numbers as close estimates. Our fake-profile rule is a rough heuristic. And the list came from Hunter's data, so it reflects the kind of execs Hunter users reach out to.
We ran the research in October 2026.
