The 7 keys in the sequence
5 emails, 1 phone call, 1 LinkedIn message — over 16 days.
Why this sequence works
With 225 prospects and a response rate of 17%, this sequence of seven touchpoints over 16 days is particularly fast-paced and targeted. The short 16-day cycle is well-suited to the HR sector, where decisions on hiring are often made quickly, unlike IT sales cycles which can stretch over months.
Mentioning client references such as PwC, L’Oréal and BNP Paribas right from the first email is a strategic move. For an HR VP, these names serve as immediate endorsements — if these companies trust the solution, it is at least worth listening to. This principle of social proof is reinforced by the team photo, which adds a human touch to the approach.
The LinkedIn connection in Touch #3, sent between two emails, creates a cross-platform presence. The prospect sees the sender’s name both in their inbox and on LinkedIn, which builds familiarity and lends credibility to the approach ahead of the phone call in Touch #5.
What you can learn from this campaign
- Condense the programme into 16 days for the HR sector. Decisions on hiring staff are made more quickly than IT purchases.
- Add a personal touch with team photos. The video call image in Touch #1 creates an immediate personal connection.
- Using YouTube videos as educational content. Touch #6 shares an explanatory video that allows the prospect to understand the solution at their own pace.
- Refer to the COVID context to create a sense of urgency. Touch #7 uses the context of change to reignite the conversation.

Frequently Asked Questions
Why is the sequence limited to 16 days?
Decisions on hiring are made more quickly than IT or security purchases. An HR VP who identifies a hiring need can make a decision within a few weeks. Extending the process to 40 days risks losing momentum. Seven touchpoints over 16 days create a steady rhythm without being intrusive.
How do client references such as PwC affect the response rate?
In our experience, mentioning well-known clients in the first email increases the response rate by 25–40% compared to an email that does not include such references. For an HR VP, seeing that PwC and L’Oréal use the solution eliminates the perceived risk. The key is to cite companies in the same industry or of a similar size to the prospect.
How can this lesson plan be adapted to the post-COVID context?
Touch #7 in this series already uses the COVID context as a conversation starter. To bring it up to date, replace the reference to COVID with the latest HR challenges: hybrid working, quiet quitting, and talent retention. The structure remains the same — only the context changes.
