The debate between cold calling and warm calling continues to divide sales teams across the UK. Both approaches have their place in modern B2B prospecting, but knowing when to deploy each strategy can make the difference between hitting your targets and falling short.
At SendIQ, we’ve seen how the right calling approach at the right time transforms lead generation results. Here’s when cold calling works best, when warm calling delivers superior outcomes, and how to maximise both strategies.
What Makes a Call Cold or Warm?
Cold calling involves contacting prospects who have had no previous interaction with your business. These leads typically come from purchased lists, research databases, or company targeting. The prospect doesn’t know you exist, and you’re starting completely from scratch.
Warm calling targets prospects who have already shown interest in your business or industry. This might include website visitors, email subscribers, social media followers, or referrals from existing clients. There’s already a foundation to build upon.
When Cold Calling Delivers Results
Cold calling remains effective for specific B2B scenarios:
-
High-volume prospecting: Works well when targeting large market segments with broad appeal products or services.
-
New market expansion: Essential when entering fresh territories where awareness hasn’t yet been built.
-
Direct decision-maker contact: Senior executives often bypass marketing content but respond to professional calls.
-
Product launches: Helps educate target personas who need your solution but don’t yet know it exists.
The Power of Warm Calling
Warm calling consistently delivers higher conversion rates because trust and awareness already exist. Examples include:
-
Website visitors who’ve browsed your services but haven’t converted.
-
Email subscribers who haven’t engaged with campaigns but may respond to a call.
-
LinkedIn connections or social interactions where interest is already signalled.
-
Referral leads where credibility comes built-in from the referring party.
Timing Your Approach for Maximum Impact
-
Cold calling works best during standard business hours, particularly Tuesday to Thursday.
-
Warm calling offers more flexibility since the prospect already knows you. These calls often feel less intrusive, even outside typical hours.
-
Seasonal timing matters too: January and September are strong months for cold outreach, while trigger events like funding rounds or leadership changes create prime warm calling moments.
Combining Both Strategies Effectively
The strongest prospecting strategies blend cold and warm calling:
-
Start with cold calling to identify interested prospects.
-
Nurture them through email outreach and LinkedIn engagement.
-
Follow up with warm calls that feel more natural and relevant.
Multi-touch campaigns create familiarity and increase response rates. Website visitor identification can also convert cold prospects into warm ones by revealing browsing behaviour and intent signals.
Measuring Success Across Both Approaches
-
Cold calling metrics: Focus on reach and initial interest. Success may look like a 2-3% positive response rate.
-
Warm calling metrics: Emphasise conversion and progression. These calls often deliver 15-20% progression rates with fewer but higher-quality interactions.
Making the Right Choice for Your Business
-
Market maturity: In competitive markets, warm calling often performs better. In emerging markets, cold outreach helps establish presence.
-
Product complexity: Straightforward solutions can thrive with cold calling. Complex solutions benefit from the trust warm calling builds.
-
Budget constraints: Cold calling may provide more volume upfront, but warm calling usually delivers higher ROI.
At SendIQ, we help businesses optimise both cold and warm calling, integrating them with email outreach, LinkedIn automation, and website visitor identification. The real key isn’t choosing one over the other, but deploying each strategically based on timing, market conditions, and prospect signals.
