Frequently asked questions

Should I send an email after every cold call to an IT prospect?

Yes, especially after leaving a voicemail. The combination produces 2.15x higher reply rates than either channel alone. Send the email within minutes of hanging up and reference the voicemail directly: 'Just left you a voicemail — wanted to follow up here too.' The two touches reinforce each other rather than feeling like separate campaigns.

How many touchpoints does it take to book a meeting through cold outreach?

The guide's 21-day sequence includes 10–12 coordinated touches across phone, email, and LinkedIn before reaching a break-up email. Most responses occur between touches 5 and 8. Stopping after two or three attempts — which most reps do — means giving up just before the inflection point where engagement typically begins.

How do I use LinkedIn alongside cold calling without being annoying?

Use LinkedIn for credibility and research rather than as a primary pitch channel. View the prospect's profile before calling so you can personalize the conversation. Send a connection request around the third touchpoint in your sequence, and only send a direct message after the connection is accepted. Keep the DM brief and reference your other outreach.

What is the right way to coordinate phone, email, and LinkedIn messages in a sales sequence?

Cross-reference channels explicitly in your messaging. After a voicemail, say so in the follow-up email. When calling after an email, open with 'I sent you an email last week about [topic] — did that land?' This creates a 'surround sound' effect that builds familiarity across touchpoints rather than making each channel feel like an unrelated cold start.
