# B2B lead generation channels, compared

Compare email, phone and LinkedIn by cost per booked meeting. A worked example with labeled inputs, plus the rules each channel carries.

Most channel comparisons ask which channel is best. A better question is which channel books meetings for your offer at a cost you can afford, and that answer sits in your own numbers, not in a general ranking.

This post sets up the comparison. It uses three channels and a made-up company, Fernhill Logistics Software, so you can see the arithmetic. Every input in the example is an invented figure for illustration, not a benchmark and not something we measured. Replace them with yours.

## Pick one measure that every channel can be scored on

Email replies, phone conversations and accepted LinkedIn messages are different events, so comparing them directly misleads. Convert each channel to the same three numbers: how many contacts you touched, how many responded, and how many meetings were booked. From those you can compute a response rate, a booking rate and a cost per booked meeting.

Cost per booked meeting adds people cost and tool cost for the month, then divides by meetings booked. The cost per meeting calculator does the same sum on your inputs.

## A worked example with invented inputs

Fernhill spends a month on each channel with the inputs below. The inputs are examples chosen to show the method. The rates and costs in the right-hand columns are computed from them.

Example inputs and computed results for one month (all inputs invented for illustration)

| Channel | Contacts touched | Responses | Meetings booked | Responses per touch | Meetings per response | Monthly cost | Cost per booked meeting |
| --- | --- | --- | --- | --- | --- | --- | --- |
| Cold email | 4,000 | 80 | 24 | 2% | 30% | $2,400 | $100 |
| Cold calls | 1,100 | 150 | 15 | 13.6% | 10% | $4,600 | $306.67 |
| LinkedIn messages | 700 | 45 | 9 | 6.4% | 20% | $1,620 | $180 |

## What the example does and does not tell you

In this example the phone channel gets the most responses per touch (13.6%) but converts the fewest responses into meetings (10%), so its cost per booked meeting ($306.67) is the highest of the three. Email responds less often per touch (2%) but books 30% of its responses and costs $100 per booked meeting.

Change one input and the order can change. That is the point: the ranking belongs to the inputs. A channel that looks expensive at 15 meetings a month can look different at 40, because tool and setup costs spread out, while people cost may not.

Also watch what a meeting is worth. If a phone-booked meeting turns into a deal more often than an email-booked one, a higher cost per meeting can still be the lower cost per opportunity. Track both.

## Rules each channel carries

Each channel has its own legal and platform rules, and they change what you can send and how often. These are the ones we checked at the sources below on 2026-10-19.

- Email: the FTC guide says the CAN-SPAM Act makes no exception for business-to-business email, requires a valid physical postal address and a clear way to opt out, requires opt-outs to be honored within 10 business days, and sets penalties of up to $53,088 per separate violating email.
- Email at volume: Google states that senders of more than 5,000 messages a day to Gmail accounts must set up SPF, DKIM and DMARC, keep the spam rate reported in Postmaster Tools below 0.30%, and support one-click unsubscribe for marketing messages. Yahoo lists a spam rate below 0.3% and says unsubscribes should be honored within 2 days.
- Phone: the FTC question and answer page says most calls to a business made to solicit sales from that business are exempt from the Do Not Call provisions. The same page says other rules, including the FCC's, can matter, so check them for your situation.
- LinkedIn: use the platform's own terms for messaging limits and automation. We did not read them for this post, so we state no limit here.

## Run your own comparison

A one-month test is enough to get a first read if each channel gets a fair share of attention.

1. Pick one list of accounts and split the contacts across channels so each channel sees comparable buyers.
2. Record touches, responses, meetings booked and meetings held per channel, plus people and tool cost for the same month.
3. Compute response rate, booking rate and cost per booked meeting for each. Do the same per held meeting.
4. Keep the channel that books at a cost you can afford, add a second channel only after the first is steady, and sequence them so a prospect does not get three messages in a day.

## Where ColdMeetings fits

ColdMeetings is software plus an API for the email lane: sending domains and DNS records, mailboxes, list import and verification, sequences, replies, meeting booking and a compliance layer that handles opt-outs and suppression. It does not book meetings for you and makes no promise about how many you will get. It gives you the numbers above on your own campaigns so the comparison uses real inputs.

## Questions

### Which B2B lead generation channel should I start with?

Start with the one where you can reach your buyers most directly at a cost you can measure. The worked example shows why the answer depends on your own response and booking rates rather than a general ranking.

### Are the numbers in the example benchmarks?

No. They are invented inputs for a fictional company, used only to show how the rates and costs are computed.
