For LinkedIn lead generation, each message usually gets more replies than a cold email, while cold email reaches far more people for less money. Which is better depends on who you sell to: senior people at larger firms tend to answer on LinkedIn, and small-business owners reply to email more than anyone. This guide is for founders choosing one channel.
Key points
- •Cold email reaches more people for less money; LinkedIn messages get more replies per message but you can send far fewer.
- •Published reply rates disagree because they measure different things. Belkins found 0.45% of all cold emails sent got a reply in 2025.
- •In the UK you can email company addresses without prior consent, but sole traders and some partnerships count as individuals.
- •In Nigeria, a 2026 court ruling against GTCO shows unsolicited marketing without a lawful basis carries real risk.
- •For most small B2B firms, a few well-researched messages on both channels beat a large send on either.
Cold email vs LinkedIn: which gets more replies?
Per message, LinkedIn usually does. Per week, cold email usually wins, because you can send many more.
The most careful cold email data we found comes from Belkins, an outreach agency that analysed 7.5 million cold emails sent in 2025. Only 0.45% of all emails sent got a reply. Founders and owners replied most (0.57%), and companies with up to 10 staff replied at 0.72%, more than three times the rate of the largest firms.
For LinkedIn there is no independent benchmark of the same size. Outreach software companies report reply rates anywhere from 5% to 25% for LinkedIn messages, based on their own users. Treat those as sellers' figures.
Why do published reply rates disagree so much?
Because they divide by different things. Belkins says the same campaign can read as about a 5% reply rate if you divide replies by emails opened, and 0.45% if you divide by emails sent. Open tracking has become unreliable since mail apps started loading tracking images automatically, so Belkins switched to the stricter number.
LinkedIn figures are often measured differently again: replies from people who accepted a connection request, which leaves out everyone who ignored it. So when you see "LinkedIn gets five times the replies of email", check what was counted before you believe it.
The practical answer is to measure your own outreach one way and stick to it. Meetings booked per 100 people contacted is the number that matters.
What does each cost per conversation?
Cold email outreach is cheap per message. You need a separate sending domain, a few inboxes, a sending tool and a good list. Once set up, each extra email costs very little.
LinkedIn costs more per conversation. Free accounts are limited, paid plans and Sales Navigator are a monthly subscription, and LinkedIn caps how many connection invitations you can send each week. The bigger cost is time: a good LinkedIn approach usually means looking at someone's profile and posts before you write.
| Cold email | LinkedIn outreach | |
|---|---|---|
| Replies per message | Low (under 1% of all sends, Belkins 2025) | Higher (vendor figures 5% to 25%) |
| How many you can send | Hundreds a week with the right set-up | Capped invitations each week |
| Cost per message | Very low once set up | Subscription plus more time per message |
| Who responds best | Owners and founders of small firms | Senior people at mid-sized and larger firms |
| Main risk | Landing in spam; breaking UK or Nigerian rules | Account restrictions for automated or mass activity |
| UK rules | PECR: company addresses yes, sole traders need consent | LinkedIn's own terms |

What are the rules on cold email in the UK and Nigeria?
In the UK, the Privacy and Electronic Communications Regulations (PECR) treat businesses and individuals differently. You can send marketing emails to limited companies, LLPs, Scottish partnerships and government bodies without prior consent, as long as you do not hide who you are and you give a working way to opt out. Sole traders and some partnerships are treated as individuals: you need their consent, or an existing customer relationship under the "soft opt-in". Keep a list of everyone who has asked not to be contacted and check new lists against it. The ICO says its guidance is under review after the Data (Use and Access) Act, so check it before you start a campaign.
In Nigeria, the Nigeria Data Protection Act 2023 requires a lawful basis, such as consent, for processing personal data, and gives people the right to object to direct marketing at any time. In June 2026 the Federal High Court in Abuja ordered GTCO to stop sending unsolicited marketing to a non-customer who had never consented, to disclose where it got his data and to pay damages. The message for anyone prospecting in Nigeria: know where every contact came from, and stop immediately when someone objects.

Which suits your buyer?
Start with who you are trying to reach.
- Owners of small businesses. Cold email works well. They read their own inbox and, as the Belkins data shows, reply more than any other group. Keep it short, specific to their business, and easy to say no to.
- Senior people at larger companies. LinkedIn tends to work better. Their email is filtered and busy; a connection request from someone who has engaged with their posts is easier to notice.
- Professional services such as accountants and lawyers. Both can work. Check whether the firm is a company or a partnership before emailing in the UK.
- Nigerian businesses. LinkedIn is smaller here (13.0 million members in late 2025, according to DataReportal), and many deals still start on WhatsApp after an introduction. Warm introductions often beat both channels.
How do you run both without annoying people?
Use one channel to warm up the other. A simple sequence for a small list:
- View the person's LinkedIn profile and react to or comment on a recent post.
- Send a short connection request with one line on why.
- A few days later, if they have not connected, send a short email that mentions something specific about their business.
- One follow-up on each channel, a week apart.
- Stop there. If they say no or ask you to stop, remove them from both.
Keep the numbers small enough that you can write each message properly. Twenty well-researched people a week will usually produce more meetings than two hundred names from a bought list.
Questions founders ask
Emailing people at limited companies, LLPs and public bodies is allowed without prior consent, as long as you say who you are and offer an easy way to opt out. Sole traders and some partnerships are treated as individuals and need consent. Data protection law still applies to the personal data you hold, so keep records of where each contact came from.
It depends how you measure it. Measured against every email sent, under 1% is common: Belkins' 2025 average was 0.45%. Measured against emails opened, figures of 3% to 5% are typical. Compare your own campaigns using the same method each time.
LinkedIn caps how many invitations you can send each week, and sending many that go unaccepted can get you restricted. Sending fewer, personalised requests to people who are likely to accept keeps you well inside it.
For a small firm doing regular outreach, its search filters and lead lists can save hours. If you only reach out to a handful of people a week, the free version is usually enough.
Use them with care. LinkedIn's terms restrict automated activity, and accounts that behave like bots can be limited. Use tools for research and reminders, and write and send the messages yourself.
