Cold email
Reaching targeted prospects at scale
Allows clear, structured outreach and follow-ups
To book five B2B sales meetings from cold email, you may need to contact anywhere from 250 to 1,000 targeted prospects, depending on your conversion rate.
At a 1% prospect-to-meeting rate, the maths is simple: 500 prospects = 5 meetings.
But sending 500 emails does not guarantee five meetings. Targeting, deliverability, messaging, follow-ups and the offer itself all affect the result.
For companies using B2B cold email to build pipeline in London, the real goal is not higher email volume. It is getting more of the right prospects into qualified sales conversations.
The Maths Behind 5 Sales Meetings
The number of prospects you need depends on how many of them convert into booked meetings.

These are working examples, not guaranteed cold email benchmarks. Performance will vary by industry, target audience, offer and campaign quality.
There is also a difference between prospects contacted and emails sent.
If you target 500 prospects and each receives an initial email plus three follow-ups, that campaign could involve up to 2,000 individual email sends.
This is why email volume alone tells you very little about campaign performance.
A well-targeted list of 300 decision-makers can create more opportunities than thousands of emails sent to companies that are unlikely to buy.
The same applies to B2B lead generation: the goal isn’t maximum activity. It is creating enough qualified conversations to build a viable sales pipeline.
Does Cold Email Work Differently in London?
Cold email works in London, but competition for attention is high.
Sales teams often target the same founders, department heads, and senior decision-makers across SaaS, FinTech, technology, and professional services. Generic outreach can therefore disappear quickly in a crowded inbox.
This does not mean London companies need to send more emails.
They need to be more selective about who they contact and why that person should care.
For example, 300 prospects that closely match your ICP may be more valuable than a database of 3,000 London businesses with little buying relevance.
The market also matters when writing the message. A campaign selling to a London FinTech company should not use the same positioning as one targeting a small SaaS business or an enterprise technology buyer.
Konsyg’s London sales outsourcing approach combines account research with email, phone and LinkedIn outreach rather than relying on email volume alone.
The objective remains simple: turn the right accounts into qualified sales conversations.
Work Backwards From 5 Sales Meetings
Five booked meetings only matter if they are with companies that could realistically become customers.
Instead of starting with a target such as “send 1,000 cold emails,” work backwards from the outcome you need.
For example: 5 booked meetings → 3 qualified opportunities → 1 potential new customer
The exact numbers will depend on your sales cycle, average contract value and close rate. But this approach makes it easier to judge whether your cold email campaign is contributing to pipeline rather than simply generating activity.
Qualification matters here too.
A meeting with someone outside your ICP should not carry the same value as a conversation with a decision-maker at a target account. Filling calendars with poorly qualified meetings can make campaign performance look better without improving revenue.
That is why B2B appointment setting should focus on opportunity quality as much as the number of meetings booked.
If the goal is five sales meetings in London, define what a qualified meeting looks like before deciding how many prospects you need to contact.
What Determines Your Cold Email Meeting Rate?
Two companies can contact the same number of prospects and end up with very different numbers of sales meetings.
The difference usually comes down to how well you build the campaign before you send the first email.
- ICP Accuracy
A strong cold email campaign starts with the right accounts.
Company size, industry, location, job title, buying responsibility, and likely need should all influence who enters the prospect list.
If the ICP is too broad, even good messaging will struggle to generate qualified meetings.
- Email Deliverability
Your prospect cannot respond to an email they never see.
Domain reputation, authentication, sending patterns, bounce rates, and list quality can all affect whether emails reach the inbox.
This is why deliverability should be treated as part of campaign performance, not simply a technical setup task.
- Message Relevance
Decision-makers receive plenty of sales emails.
A message that could have been sent to any company gives them little reason to respond. The email should connect your offer to a problem, priority, or situation relevant to that specific audience.
Personalisation does not necessarily mean writing a completely different email for every prospect. It means making the message specific enough that the recipient understands why you are contacting them.
- The Offer
Even a well-written email will struggle if the next step is unclear or requires too much commitment.
The prospect needs a credible reason to keep the conversation going.
Instead of trying to sell the entire service in the first email, the objective should usually be to create enough interest for a relevant sales conversation.
- Follow-Ups
Many prospects will not respond to the first email.
They may be busy, miss the message or simply not have enough context to reply immediately.
A structured follow-up sequence gives the campaign additional opportunities to start a conversation without constantly adding new prospects.
Other channels can also help. Cold email can be supported by cold calling and LinkedIn outreach when the account is worth pursuing.
If a campaign contacts hundreds of relevant London prospects but books very few meetings, don’t increase volume first. Find the weakest part of the campaign first.
Cold Email vs Cold Calling vs LinkedIn for London B2B Sales
Cold email does not have to work alone.
Some prospects will respond to an email. Others may be easier to reach by phone or become familiar with your company through LinkedIn before responding.
The right channel depends on the account, the decision-maker and the type of sale.
Cold calling
Starting direct conversations
Provides immediate feedback and qualification
LinkedIn
Building familiarity with decision-makers
Adds another touchpoint around the account
For a London B2B campaign, these channels can support each other.
An SDR might email a prospect, connect with them on LinkedIn and follow up with a call. If the prospect does not respond to one channel, the campaign still has another opportunity to start a conversation.
This becomes particularly useful when targeting a smaller list of high-value accounts. Rather than continuously adding new contacts, sales teams can focus their effort on the decision-makers that matter.
Multichannel outreach isn’t about contacting prospects everywhere at once. It is about creating enough relevant touchpoints to improve the chance of a genuine sales conversation.
Should You Run Cold Email In-House or Outsource It?
Running cold email internally gives your company direct control over targeting, messaging and sales conversations.
But the cost is not limited to hiring an SDR.
A functioning outbound programme may also require prospect data, list building, email infrastructure, deliverability management, copywriting, campaign tools, reporting and ongoing optimisation.
For companies with an established sales development team, keeping these functions in-house can make sense.
Outsourcing becomes more relevant when a company wants to build pipeline without first creating the entire outbound operation internally.
A sales outsourcing partner can manage prospect research, outreach, follow-ups and appointment setting while the internal sales team focuses on opportunities once they enter the pipeline.
The decision should therefore come back to economics.
If your target is five qualified meetings, compare the total cost of generating those meetings internally with the cost of having an external team run the campaign.
Do not compare the options on meeting volume alone.
Look at the quality of the accounts reached, meetings held, opportunities created and pipeline generated. A cheaper campaign that fills the calendar with poor-fit prospects can ultimately cost more than a campaign producing fewer but better-qualified conversations.
What Should You Measure Beyond Meetings Booked?
Five booked meetings can look like a successful cold email campaign.
But the meeting count does not tell you whether those conversations are likely to create revenue.
A stronger way to evaluate performance is to track what happens throughout the campaign and after you book the meeting.
Key metrics include:
- Delivery rate: Are your emails successfully reaching prospects?
- Positive reply rate: How many prospects show genuine interest?
- Prospect-to-meeting rate: How many targeted prospects become booked meetings?
- Meeting-held rate: How many booked meetings actually take place?
- Qualified opportunity rate: How many meetings progress into real sales opportunities?
- Pipeline generated: What potential revenue can be connected to the campaign?
For example, two campaigns might both generate five meetings.
One produces five conversations but no qualified opportunities. The other produces three qualified opportunities worth £90,000 in potential pipeline.
The meeting count is identical. The commercial result is not.
This is why B2B cold email should ultimately be measured against pipeline contribution, not just the number of calendar bookings.
For London companies investing in cold email, the question should move from “How many meetings did we book?” to “How many of those meetings can realistically become customers?”

Frequently Asked Questions
How many cold emails does it take to book one B2B meeting?
There is no fixed number. At a 1% prospect-to-meeting rate, you would need to contact around 100 targeted prospects to generate one meeting. Results depend on your ICP, deliverability, messaging, offer and follow-up strategy.
What is a good cold email meeting rate?
Meeting rates vary considerably by industry, audience and campaign quality. Rather than relying on a universal benchmark, track your own prospect-to-meeting rate alongside qualified opportunities and pipeline generated.
How many follow-ups should a B2B cold email campaign use?
No single sequence works for every campaign. Several relevant follow-ups can give prospects more opportunities to respond, but each message should have a clear reason for being sent rather than simply repeating the original email.
Is B2B cold email legal in the UK?
B2B cold email can be lawful in the UK, but organisations must consider UK GDPR and PECR requirements. The applicable rules can differ depending on the type of recipient, how contact information was obtained and how personal data is processed. Businesses should ensure their outreach practices comply with the requirements that apply to their campaign.
