EmailDay 1Introduction
Subject: A] Our call {{firstName}} – cyber-resistance\nB] cyber-resistance – our call {{firstName}}
Hello {{firstName}}, {{Icebreaker — e.g.: Your background and qualifications in IT security are impressive — I’ve had a look at your LinkedIn profile.}} {{PainPoint — e.g.: As you’re no doubt aware, the number of cyberattacks in Switzerland doubles every year, and most of them target Active Directory. Our clients in the {{industry}} sector have turned to our solution to improve their cyber resilience and better withstand the next ransomware attack.}} In a (very) nutshell, our solution: - identifies and prioritises all attack vectors so you can focus your attention on the most dangerous ones - provides prioritised, actionable recommendations to reduce risks associated with your access configurations - maps your entire AD (and/or Azure AD) to provide you with a continuous risk score Time and resources are limited, but with our solution, you know what to prioritise to improve your resilience to attacks. We suggest the actions that require the least effort for the greatest improvement. If reducing your attack surface is a priority, would you be willing to discuss this with our CEO [CEO_first_name]? Kind regards, Charles PS: All our partners have reduced their internal attack surface by over 60% thanks to [CompanyName].
Email3 days laterProposal
Subject: (same item)
Hello {{firstName}}, Given the importance of {{CompanyName}}’s cyber resilience, I would like to make a proposal and provide further background on [CompanyName]. We would be happy to carry out a security audit of your internal environment (AD, Azure AD). Instead of paying consultants between CHF 20,000 and CHF 100,000 for a pentest or a limited, one-off audit, we are offering you a 30-day trial at a fraction of that cost to continuously analyse your entire attack surface. From experience, the results are guaranteed. Before using [CompanyName], our clients were faced with thousands of recommendations based on qualitative compliance. It took time to understand where to start and identify the most critical issues within the context of their organisation. Now they know where to focus their attention and which actions to take first, thanks to simple, prioritised and context-specific recommendations. [CompanyName] is a Swiss company based in Lausanne and part of Trust Valley. We offer on-premises or cloud deployment in Switzerland or across Europe. Could you spare 45 minutes to discuss your cyber resilience? You can book a time of your choice directly in [CEO_first_name]’s calendar (but if you prefer, I can also send you two or three suggestions). Thank you in advance for your reply, Kind regards, Charles PS: Here’s a little virtual coffee to help you get on with your day :)
Email4 days laterShare brochure
Subject: (same item)
Hello {{firstName}}, I imagine you’re quite busy at the moment? The offer in my last message to trial our solution for 30 days at a very competitive price still stands. I invite you to read our short brochure to understand how graph theory and machine learning techniques enable our solution to continuously map an organisation’s attack surface, identify the most likely attack paths and suggest remedies. Please also note that if your environment is hybrid, our solution analyses not only Microsoft Active Directory, but also Azure Active Directory and the relationship between the two. Does your organisation use AD, Azure AD, GCP, AWS, or an internal directory? Have a good day, Kind regards, Charles
Email5 days laterContact a colleague
Subject: (same item)
Hello {{firstName}}, I hope you are well. I haven’t heard back from you, so I was wondering whether I should contact you or your colleague {{colleague_name}}? Thank you in advance for your reply, Kind regards, {{salesRep}}
Call4 days laterFirst call
If the prospect replies: "Hello {{firstName}}, this is {{salesRep}} from [CompanyName]. I’ve sent you some emails about our solution, which can help you improve your cyber resilience, particularly by saving you time and money. Would you have two minutes to spare to see if we could be a good fit for you?" If so: "As you are no doubt aware, in Switzerland the number of cyberattacks doubles every year, and in 80% of audits carried out in 2020, the IT system was compromised within 24 hours (according to Wavestone). In light of this, 53% of large enterprises and SMEs have an AD security project in place. Our solution addresses three common issues: 1) prioritising the actions to be taken, 2) an audit that never stops, 3) a very affordable cost. Our clients have reduced their internal attack surface by over 60% in just a few months." If interested → Qualification questions + schedule a demo. If not interested → Rephrase the problem, handle objections politely. If voicemail: "Hello {{firstName}}, this is {{salesRep}} from [CompanyName]. I hope you’re well. I’ve been trying to get hold of you as you might be interested in finding out how our clients have reduced their attack surface by over 60%. Would you have a minute to discuss cybersecurity? You can call me back on this number or email me. Have a good day."
Email1 day laterAfter the call
Subject: (same item)
Hello {{firstName}}, I hope you’re well. I tried to reach you by phone yesterday regarding our attack prediction solution (my mobile number is [Number]). Would it be possible for me to call you back at a more convenient time to discuss whether our solution is the right fit for you? Thank you in advance for your reply, Kind regards, {{salesRep}}
Call3 days laterSecond call
Same approach as Touch #5. Second attempt to call prospects who didn’t answer the first time. Objective: to speak to the prospect in person. Vary the time of the call from the first attempt (if the first call was in the morning, try again at the end of the day).
Email1 day laterLast email (breakup)
Subject: (same item)
Hello {{firstName}}, I tried to get in touch with you again yesterday, but it seems you have a busy schedule. If there’s a better time, or if you’re not interested in finding out how our solution can add value, please do let me know so that I can stop contacting you. I believe our solution might be of interest to you, as it replaces numerous audits and penetration tests with a single continuous analysis tool, covering the entire internal attack surface at a significantly lower cost. Alternatively, could you let me know if I should speak to another of your colleagues? Perhaps {{colleague_name}}? You’ll find our brochure here just in case, but I’m always available if you have any questions or would like to discuss protecting your infrastructure against the most damaging attacks. Thank you in advance for your reply, and I wish you all the best for the future. Kind regards, {{salesRep}}

Hello {{firstName}}, this is [CEO_first_name] from [CompanyName]. I look forward to connecting with you and learning about the projects and insights you’re working on at {{companyName}}. See you soon

Why this sequence works

This campaign observed a 54% response rate with a carefully orchestrated multi-channel sequence. The six emails do not repeat the same message: each touchpoint offers a new angle of value. The introduction sets out the problem, the second email proposes a concrete action, the third shares a technical resource and the fourth offers an easy route to the right contact.

Making the first phone call at Touch #5, after four emails, is a deliberate sequence choice. The prospect may already recognise the sender’s name, and the call can revisit issues introduced by email. Treat that familiarity effect as a hypothesis to test with each audience.

A/B testing the first subject line lets you compare formulations on a defined sample. The “virtual coffee” PS in Touch #2 humanises an otherwise technical exchange. Measure the effect on opens and responses by variant.

What you can learn from this campaign

  • Organise 30 days into 9 sections. The follow-up schedule is staggered: 3 days between the first emails, then 4–5 days, with calls concentrated in the second half of the fortnight. This gradual build-up prevents the prospect from becoming overwhelmed too soon.
  • Using a variety of channels increases reach. A CISO might ignore emails but answer the phone, or vice versa. Combining email, phone and LinkedIn creates different contact opportunities; measure each channel’s contribution within your cohort.
  • Quantitative social proof instantly lends credibility. A quantified result supports credibility only when it is verified and attributable to the named client. Compare it with qualitative copy in a controlled test before drawing conclusions about CTA performance.
  • The breakup email (Touch #8) wins over the undecided. By announcing the end of the sequence, you give the prospect an easy way to respond: postpone, decline or accept a call. Measure this variant against a standard final email.
  • Make the call after four emails, not before. Touch #5 is the first call. By this stage, the prospect has had four opportunities to see your name. Verify within your cohort whether that context improves pick-up compared with a first-contact call.

When to use this sequence

Targeting CISOs and security decision-makers

Your ICP includes CISO, CIO, DPO, CTO and other similar roles. These professionals receive a high volume of communications — the multi-channel approach is designed to reach them.

Sales of cybersecurity or IT solutions

Whether your product focuses on access management, threat detection, security auditing, compliance or infrastructure protection, the value proposition can be easily adapted.

Regulated industries

Finance, healthcare, the public sector, energy — organisations in these industries face compliance obligations that make cybersecurity a top priority. The urgency is already there.

Sales cycle of 3 to 6 months

The 30 days of this sequence cover the initial engagement phase. For complex deals involving multiple decision-makers, it is used to secure the first meeting.

Who can use this sequence?

Cybersecurity sales teams

If you sell IT security solutions (SIEM, PAM, IAM, penetration testing, GRC), this sequence is your starting point. Tailor the value proposition to your product.

SDRs aimed at IT security professionals

The call script includes qualification questions and objection-handling techniques specific to the cybersecurity sector. Ready to use.

Cybersecurity channel partners

System integrators, resellers, security consultants — if you represent a software vendor, this guide will help you structure your sales approach from start to finish.

Any B2B publisher selling to CISOs

Even outside the realm of pure cybersecurity, if your buyer persona is the CISO (e.g. backup, cloud, compliance), the structure and timing of this sequence still apply.

Frequently Asked Questions

How many keystrokes are required in a cybersecurity sequence?

This campaign uses nine touchpoints over 30 days to alternate email, phone and LinkedIn without repeating the same message. Treat that format as a starting point: adapt the number of touches and channels to audience signals, then compare cohorts.

When is the best time to contact a CISO?

Test several calling windows around the audience’s time zone and working patterns. In this sequence, the first call comes at Touch #5 after four emails; compare that placement with an earlier call before treating it as a rule.

How can I tailor this sequence to my business?

Adapt three elements: (1) replace the icebreaker with a real event from the prospect’s context. (2) Use only verified metrics in the value proposition. (3) Cite a comparable client with permission. Test the structure and timing on your own audience as well.
