How to use Ads + Email to Warm Up Cold B2B Leads

In the realm of B2B digital marketing, converting cold leads into warm prospects is both an art and a science.

Well-crafted and optimized ads are essential to any marketing strategy. So is email marketing. But how well do you combine the two? More importantly, can these channels communicate with each other to maximize their impact?

The ads + email synergy presents a powerful opportunity to engage with cold leads and guide them through the customer journey. When used strategically, the channels complement each other in ways that can significantly improve conversion rates.

In this article, we’ll explore two effective approaches to integrating ads with email into a cohesive strategy that nurtures leads and turns them into clients.

Let’s get into it…

B2B Lead Warming – Bringing the Heat Through Psychology

Effective lead nurturing means understanding the psychology of the B2B decision makers.

Cold leads are professionals navigating complex organizational challenges. Each touchpoint in your marketing strategy represents an opportunity to build trust and demonstrate value.

When a prospect receives your email or encounters your ad, they’re subconsciously evaluating several critical factors:

• Relevance to their specific business challenges
• Credibility of the solution provider
• Potential return on investment
• Alignment with their existing processes

Successful lead warming strategies recognize that B2B purchases are fundamentally emotional decisions disguised as rational ones. Decision-makers seek more than a product or service – they also seek a partner who understands their unique ecosystem.

For instance, a cybersecurity software company targeting financial institutions should demonstrate awareness of regulatory compliance challenges, evolving threat landscapes, and the high-stakes nature of data protection.

Approach 1: Cold Outreach -> Retargeting Ads

Starting with email allows direct engagement with prospects before introducing ads to reinforce messaging. This method works well for industries where outreach can be highly targeted, such as enterprise software, niche consulting, and specialized B2B services.

What You’ll Need

• UTM Links – These track which recipients visit your landing page and if they come from your ads or emails.
• Tracking Pixels – Platforms like Google Ads, Facebook, and LinkedIn allow you to track website visitors.
• Ad & Email Copy – Messaging should align with email content to maintain consistency.
• Retargeting Campaign Setup – Create audience segments based on website activity.
• Email Marketing Platform – Cold outreach tools such as Clay, Apollo, or Instantly.
• Nurture Sequence – A follow-up email series for engaged prospects. The number of emails and content will vary based on industry and sales cycle length.

How to Do It

• Send an Initial Email Blast – Build a list of high-potential contacts. Personalization increases engagement, so include relevant details about their industry or pain points (these depend on your own industry and your target personas). The goal is to drive recipients to your website.
• Track Engagement – Using the UTM links, you will monitor email-driven website visits. If an email recipient clicks a link but doesn’t take action, retargeting ensures they see the offer again. You can use Google’s URL builder to build your UTM links.
• Optimize Follow-Ups – Prospects who engage with emails and ads are more likely to convert. Send additional emails tailored to their behavior, such as a case study if they visited the services page or a webinar invite if they engaged with educational content.
• Monitor and Adjust – Review ad performance & email engagement to refine messaging. High-performing emails can inform ad copy, and vice versa.
• Launch Retargeting Ads – Set up campaigns that show ads to website visitors (from the email campaign) who didn’t convert. Platforms like LinkedIn and Meta allow custom audiences based on website activity. Google’s Display Network can also serve reminders across the 2m+ websites within the network.

If you want to dive deeper

In the initial email blast, personalization goes far beyond using a recipient’s name. True personalization requires deep research and contextual relevance, which is considered part of account-based marketing. Consider some advanced personalization techniques.

Approach 2: Ads -> Email Outreach

Instead of sending emails first, this method identifies website visitors through ads before reaching out via email. It works well for industries where lead lists are harder to build, such as emerging SaaS companies or newer service-based businesses.

What You’ll Need

Everything from the previous approach, plus:

• Person-Level Website Visitor Identification Tool – Services like RB2B help uncover the companies visiting your site.

How to Do It

• Launch a Paid Ad – Ads should drive relevant traffic to a dedicated landing page. If visitors are already searching for solutions like yours, they are more likely to engage.
• Track Visitors with Identification Tools – A tool like RB2B matches website visitors to company employees. If your ideal prospects are engaging with content but not converting, you can reach out directly.
• Build an Outreach List Based on Website Visitors – Instead of a broad email campaign, outreach focuses on people who have already expressed interest. LinkedIn Sales Navigator and Apollo can help find decision-makers at these companies.
• Send Targeted Emails – Your message should acknowledge the recipient’s potential interest. For example, “Looking for resources on [specific topic]? We have just what you need”
• Bonus step – back to ads – Even after email outreach, continue serving ads to non-responders. This keeps your brand visible and increases the chances of conversion.

Advanced techniques

This approach creates a list of engaged prospects rather than sending emails blindly. People who visit your website through ads already have some level of interest, making them more receptive to outreach.

How do you choose?

As explained earlier, your choice depends on your industry and your ICP.

A consulting firm with a well-defined client profile might find cold email first to be more effective. A SaaS company looking for inbound interest might prefer ads first. Testing both methods will help determine what works best.

A Decision Matrix for Approach Selection

Create a comprehensive evaluation framework:

1.Industry Characteristics Assessment

• Market maturity
• Sales cycle complexity
• Typical buyer research behaviors
• Competitive landscape density

2.Organizational Capability Audit – Evaluate your team’s strengths:

• Email marketing expertise
• Ad campaign management skills
• Data analysis capabilities
• CRM and marketing automation maturity

3.Experimental Approach

a. Implement a 9-12 month split testing strategy

b. Allocate 30% of marketing resources to each approach

c. Continuously measure:

• Customer acquisition cost
• Conversion rates
• Quality of generated leads
• Sales cycle length

The landscape of B2B lead warming is not a one-size-fits-all strategy, but a dynamic, iterative process of understanding and connection. Success lies in recognizing that every interaction is an opportunity to build trust, demonstrate value, and align with your potential client’s unique business challenges. Whether you choose cold outreach with retargeting ads or begin with targeted advertising, the key is to remain adaptable, data-driven, and genuinely focused on solving your prospects’ most pressing problems.

Marketing technologies and tactics will continue to evolve, but the fundamental principles remain constant: know your audience, provide meaningful value, and create a communication strategy that feels less like a sales pitch and more like a collaborative solution. By embracing these approaches with creativity, empathy, and strategic precision, you can transform cold leads into engaged partners who are not just interested in your offering, but genuinely excited about the potential of working together.
