Let’s be honest—picking up the phone in 2025 is no joke. With LinkedIn DMs, AI emails, and perpetual robotization, old-school deals calls can feel outdated… unless you're doing them right. Whether you’re cold calling a stranger or warm calling a lead who’s already interacted with your brand, both approaches have their place in a modern sales strategy.

In this guide, we’ll break down the real differences between warm calling and cold calling, their pros and cons, and how to make both work smarter, not harder.

What Is Cold Calling?

Cold calling is when you reach out to a prospect who has had no prior interaction with your brand. You’ve never emailed, met, or spoken with them—they probably don’t even know who you are. This method is often used by:

• SDRs/BDRs doing outbound prospecting.
• Sales teams are trying to open new accounts.
• Founders are doing grassroots sales for early traction.

Despite its reputation, cold calling still works when done correctly. According to Cognism, 82% of buyers are open to booking meetings after a cold outreach attempt... if it’s relevant and personalized.

What Is Warm Calling?

Warm calling happens when the prospect has already engaged with your company in some way—maybe they downloaded a whitepaper, filled out a form, attended a webinar, or even just visited your website. Warm calling is about building on prior intent, not creating it from scratch. Familiar sources of warm leads:

• CRM contacts from past campaigns.
• Inbound form submissions.
• Event signups or webinar attendees.
• Email responders or newsletter subscribers.
• LinkedIn connections or prior conversations.

This method is often more successful and less stressful for sales reps.

Tips to Improve Success Rates

For Cold Calls:

• Personalize fast: Use company news, LinkedIn activity, or mutual connections.
• Be direct: Grab attention in the first 15 seconds.
• Don’t pitch too soon: Ask a question to start a conversation.
• Time it right: Mornings and late afternoons often work best.

Example cold call opener: “Hi [Name], this is [You] from [Company]. I noticed you’re hiring SDRs and wanted to share something that helped a similar company reduce ramp time by 40%. Got a minute?”

For Warm Calls:

• Reference their action: “You downloaded our pricing guide last week...”
• Provide value upfront: “Just wanted to offer a quick walkthrough if you had questions.”
• Ask about timing: “Is now a good time to chat, or should I follow up later this week?”

Warm call script example: “Hi [Name], thanks for checking out our ROI calculator last Thursday. Just wondering—were you exploring tools to optimize your sales funnel?”

Can You Combine Both?

Absolutely. Here’s a winning workflow:

• Start cold: Outbound email or call to a prospect list.
• Warm them up: Invite them to a webinar or send a valuable resource.
• Call post-engagement: Now it’s a warm call with context.

Top-performing sales teams use this hybrid approach to move leads down the funnel without being pushy or disconnected.

Conclusion

Both cold and warm calling play vital roles in a forward-thinking sales strategy. Cold calls help you open new doors, while warm calls let you walk through them with clarity, context, and confidence.

The key isn't choosing one over the other — it's about adapting your outreach based on where your prospects are in their journey. With the right timing and personalized approach, phone outreach in 2025 can still drive major deals.
