Why does the number of touches matter so much?
Most B2B prospects do not reply to the first contact, or even the second. This is not rudeness; it is the ordinary consequence of a full inbox, competing priorities, and a decision cycle that rarely moves at the pace an SDR would like. The cumulative contact model works because each touch increases the probability that you catch the right person at the right moment. Miss a week and that probability resets somewhat.
The 5-to-9 touch range has held up across a reasonable body of sales development research and practitioner data. Below 5 touches, a significant cohort of prospects never receives enough contact to form any opinion at all. Above 9, the reply-rate increment per additional touch typically falls below the cost of running it. Seven touches over 4 to 5 weeks is a practical default for mid-market UK B2B deals (£20k to £200k ACV).
The critical variable is not just the number of touches, but the channels those touches use. A seven-email cadence and a seven-touch mixed-channel cadence are not equivalent. The mixed-channel version reaches the prospect through three different cognitive contexts: their inbox, their phone, and their letterbox. That spread materially reduces the chance that your entire outreach effort is neutralised by a single spam filter or an overfull voicemail box.
What does a proven 8-touch B2B cadence look like?
Below is a sequencing pattern that works well for mid-market UK deals. Each touch has a job. None of them should repeat the same message word-for-word from the previous contact.
- Day 1, email-1: Short, direct, one clear hypothesis about why this is relevant to the prospect. No attachments. No more than 120 words.
- Day 3, email-2: A different angle, not a "just following up" repeat. Add a specific reference (a company announcement, a sector event, a shared connection).
- Day 5, phone-1: First dial. If voicemail, leave a 20-second message referencing the emails. If no voicemail available, note the attempt and move on.
- Day 7, LinkedIn: Connection request or InMail. Keep it brief. Reference the emails if the request allows text.
- Day 10, direct mail (dimensional): A physical package, posted first class. A short handwritten note (or facsimile) inside performs better than a printed letter alone. Arrives typically day 11 to 13.
- Day 14, phone-2: Reference the package. "I sent you something last week, I wanted to check you received it" is a natural, non-aggressive reason to call.
- Day 17, email-3: The "permission to close" email. Make it easy for the prospect to say no cleanly so that the relationship does not end on an awkward note.
- Day 21, phone-3: Final dial. If no response after this, mark as inactive and re-queue in 90 days with a fresh message.
This structure compresses well if your lead times are shorter: a five-touch version collapses to email-1, email-2, phone-1, LinkedIn, email-3 (the "break-up" mail) over 10 to 14 days. The dimensional mail step is removed when ACV does not justify the cost.
When should you add phone to an email cadence?
The honest answer is a cost-per-acquisition calculation, not a rule of thumb about "high-value prospects." Work backwards from what a call actually costs.
An SDR dialling cold will typically reach a live decision-maker on roughly 15 to 25% of dials (the connection rate varies by sector, seniority level, and list quality). If you are paying an SDR £35,000 per year and they make 40 dials per day across 220 working days, the cost per connected conversation runs to approximately £30 to £40. Add telephony charges, list cost, and management overhead and the all-in cost-per-contacted prospect sits at £20 to £50 for most UK B2B operations.
That number needs to be a small fraction of the deal value for the maths to work. At £5k ACV with a 20% close rate from a contacted prospect, the expected value of the conversation is £1,000. Spending £40 per contact to reach that conversation is feasible, but only if the email cadence alone cannot achieve a similar outcome at lower cost. At £10k ACV, the expected value rises to £2,000, and the calculation becomes easier.
As a practical threshold: add phone when ACV reaches roughly £20,000, or when your email-only cadence reply rate is below 3% after 3 touches. If you are running B2B telemarketing at scale, the cost curve improves significantly with volume and with a cleaner, more targeted list.
TPS compliance before every dial
Under the Privacy and Electronic Communications Regulations (PECR), you must not make live marketing calls to numbers registered on the Telephone Preference Service (TPS). Businesses can and do register on TPS, so washing your dial list against TPS is mandatory before every campaign, not a one-off. The Information Commissioner's Office (ICO) has issued fines for non-compliance. A typical TPS wash costs less than £1 per 1,000 records; the risk of skipping it is disproportionate.
When does direct mail justify its place in the cadence?
Flat direct mail (a standard A4 letter in an envelope) is inexpensive but rarely breaks through at C-suite level. Dimensional direct mail, by contrast, is a physical object that requires a decision to open, creates a tactile memory, and sits on a desk rather than disappearing into an inbox. The downside is cost: fulfilment, packaging, print, and Royal Mail tracked postage combined typically run £15 to £40 per piece for a reasonably well-produced item.
That cost is proportionate when ACV exceeds roughly £50,000. A target list of 200 firms at that deal size, with a realistic 5% conversion from meeting to closed deal, means four closed deals expected. At £50k each, that is £200,000 in revenue from a direct mail spend of £8,000. The ratio holds. At £10k ACV, the same maths produces £40,000 in revenue against £8,000 spend, and the margin arithmetic starts to look difficult once you account for delivery costs, SDR time, and sales cycle length.

What sectors respond best to dimensional mail?
Regulated sectors with high email volumes tend to respond well: financial services (particularly wealth management and corporate finance), legal, healthcare procurement, and senior public-sector buying roles. These audiences are systematically saturated with cold email, but they still open post. In our experience, response rates on cold direct mail to verified C-suite contacts beat cold email by a factor of 3 to 5 in those sectors. The contrast effect alone is worth something when your competitors are sending a sixth email.
B2B cadence by ACV: a practical reference table
The table below maps deal size to recommended cadence structure. These are starting-point recommendations, not rigid rules; your sector, prospect seniority, and list quality will all shift the optimal mix.
| ACV range | Recommended touches | Channels | Approximate cadence duration | Estimated cost per contact |
|---|---|---|---|---|
| Below £10k | 3 to 5 | Email only | 2 to 3 weeks | £1 to £3 |
| £10k to £20k | 5 to 6 | Email + LinkedIn | 3 to 4 weeks | £3 to £8 |
| £20k to £50k | 6 to 8 | Email + phone + LinkedIn | 4 to 5 weeks | £25 to £60 |
| £50k to £200k | 7 to 9 | Email + phone + LinkedIn + dimensional mail | 5 to 6 weeks | £50 to £100 |
| Above £200k | 8 to 10+ | All channels, bespoke gifts or research reports | 6 to 10 weeks | £100 to £250+ |
The "estimated cost per contact" figures assume you are using a verified, targeted list rather than a broad, unverified file. Low-quality data inflates cost by increasing the proportion of bad dials, returned mail, and bounced emails. For advice on what to look for in a B2B data file before building a cadence, the rules governing cold email to business contacts are covered in our guide to cold email B2B UK rules.
How should touches be spaced across the cadence?
A gap of 1 to 3 business days between touches is the right default. Shorter than that and you risk appearing aggressive, particularly on email where back-to-back sends flag spam filters and damage sender reputation. Longer than 5 days and you lose the recency effect: the prospect has moved on mentally and your earlier contact has faded.
Phone calls can sit at slightly longer intervals than email, 2 to 4 days, because a voicemail or missed call is more intrusive than a silent email and the prospect needs a little more breathing room. LinkedIn messages should come after at least one email has been sent; connecting with someone who has never heard of you carries a lower acceptance rate than connecting when your name is already in their inbox.
Dimensional direct mail has a practical constraint: production and delivery lead time. Even with Royal Mail tracked 24-hour delivery, a physical package takes 1 to 3 days from despatch. Budget accordingly and sequence it at a natural pause point in the cadence, typically between days 10 and 14, so it arrives before the second phone call rather than after it.
Pausing and re-queuing stalled prospects
Not every prospect will engage in a single cadence run. A contact who does not reply after 8 touches is not permanently disqualified. Re-queue them at 90 days with a completely fresh message that does not reference the previous sequence. Trigger events (a new job title at Companies House, a funding announcement, a sector event) are valid reasons to re-approach earlier.
One practical note on UK data hygiene: B2B contact records decay at roughly 20 to 30% per year as people change roles. A contact list pulled 18 months ago may have a quarter of its records pointing at the wrong person. Run a data refresh before any new cadence rather than burning through stale contacts at high per-touch cost.
