Cold Calling vs. Cold Emailing: Which Prospecting Technique Reigns Supreme in 2025?

B2B sales prospecting has changed significantly. Buyers are busier, more intelligent, and more difficult to reach. With emails piling up and phones answered by gatekeepers, sales teams repeatedly wonder:

Do I focus on cold calling or cold emailing?

The debate on Cold Calling vs. Cold Emailing, has been going on for over two decades. Each method has passionate advocates. Some say picking up the phone is still the fastest way to build trust, while others argue that email is more efficient and scalable.

But the actual answer in 2025 is more complex. In order to choose, we must deconstruct the strengths, weaknesses, and best practices of both and identify how advanced AI, such as Pepsales AI, is revolutionizing the game.

What Is Cold Calling in Sales?

Cold calling is the art of calling into the unknown, reaching out to prospects by phone who have not previously engaged with you. It's personal, intimate, and sometimes difficult.

Strengths of Cold Calling

• Real-time human interaction: There's no substitute for a live conversation when you can observe tone, emotion, and intent. 

• Objection handling in real-time: You don't have to wait days to hear back from someone. You can resolve concerns right away.

• Qualification within minutes: In 2–3 minutes, you can tell if a prospect is a good fit or not.

• Higher-quality appointments: Elite sales teams achieve 8–12% conversion rates using personalization and structured phone sales methods.
  

Weaknesses of Cold Calling

• Low answer rates: B2B call pick-up rates range between 2–10%, by industry.

• Time-consuming: A rep can only manage 40–80 dials in a day.

• Rejection-ridden: Cold calling involves endurance and self-confidence to endure many "No's."

Best use case? Cold calling excels when pursuing mid-to-large deal sizes where relationship-building is important.

What Is Cold Emailing in Sales?

Cold emailing means sending a personalized, unsolicited email to a prospect. It's measurable, repeatable, and less difficult to scale than calls.

Strengths of Cold Emailing

• Highly scalable: Hundreds of prospects may be reached per day.

• Cost-efficient: Compared to call centers, it uses fewer resources.

• Measurable metrics: Monitor open rates, click-throughs, responses, and A/B testing of subject lines.

• Non-intrusive: Prospects can respond at their convenience.

Weak points in Cold Emailing

• Inbox congestion: Prospects see hundreds of sales emails a week. It's hard to stand out.

• Spam risks: Poorly written emails can hit a filter or hurt sender's reputation.

• Delayed communication: As opposed to a call, objections or questions require several back-and-forths.

Best application? Cold emailing is best applied to top-of-funnel lead generation, account warming, and mass prospecting at scale.

What the Data Says

• Cold Calling: RAIN Group says 57% of C-level buyers prefer to be phoned over emailed.

• Cold Emailing: Backlinko found that the average cold email response rate is 8.5%, but personalization boosts this by 2–3x.

• Best Outcomes: A multi-channel method (calls + emails) increases engagement by as much as 50% (LeadSpot study).

Prospecting Best Practices for 2025

For Cold Calling:

1. Strive for a 40:60 talk-to-listen ratio, listen more.

2. Utilize sales call strategies such as open-ended questions to uncover pain.

3. Use a cold calling script for a framework, but make it conversational.

4. Call during best times (Wednesdays & Thursdays, late mornings and late afternoons).

5. Use AI call assistants to guide live and prompt questions.

For Cold Emailing:

1. Personalize subject lines and openings to grab attention.

2. Shorten emails (2–4 sentences) and make them value-driven.

3. Include a strong CTA (call-to-action) — e.g., "Would you be willing to chat for 10 minutes?"

4. Avoid spam triggers (too many links, salesy tone).

5. Automate follow-ups, but space them naturally.
   

Which Wins: Cold Calling or Cold Emailing?

The reality? Neither wins hands down.

1. Cold calling is high-impact but low-volume.
   
2. Cold emailing is of high volume but lower impact.

The actual winner in contemporary B2B sales outreach is a hybrid approach:

• Begin with cold emails to pre-warm leads.

• Then proceed with cold calls to customize and speed up.

• Utilize AI tools to align insights from both channels.
