1:1 ABM: Strategies to Create High-Impact Personalized Campaigns

Account-based marketing (ABM) isn’t one-size-fits-all. While one-to-many campaigns can be effective, a generic message doesn’t always resonate across industries and personas—especially when targeting enterprise accounts with complex buying groups. 

That’s where more personalized approaches like one-to-one and one-to-few deepen engagement by tailoring messaging to specific individuals or groups within an account. 

What is 1:1 ABM?

One-to-one ABM is the most personalized form of account-based marketing, targeting a single account with hyper-personalized messaging. Instead of broad campaigns, one-to-one ABM is tailored based on real-time interactions, intent signals, sales conversations, and behavioral data.

Unlike traditional ABM, which often focuses on account-level engagement, one-to-one ABM shifts the lens to individual decision-makers and influencers. It’s more aligned with contact-based marketing (CBM)—an evolved approach that:

  • Identifies and reaches the right people inside your target accounts
  • Builds personal-level audiences based on behavior, firmographics, and intent
  • Delivers personalized ad campaigns across channels
  • Enables automated outreach and lead routing based on real-time engagement

This level of granularity helps marketing and sales teams prioritize outreach, customize messaging, and ultimately convert more of the right buyers.

1:1 ABM vs 1:Few vs 1:Many

Understanding how one-to-one compares to one-to-few and one-to-many ABM strategies is key to choosing the right approach:

1:Few ABM

  • Targets a small group of accounts (e.g., within the same industry, company size, or those experiencing similar challenges) 
  • Balances personalization with scalability, allowing companies to create industry-specific or persona-based messaging

1:Many ABM

  • Uses broad campaigns to reach multiple accounts at once with a uniform message 
  • Limits personalization making it harder to deeply engage different industries or buying roles

If you’re targeting high-value enterprise accounts, a one-to-one approach ensures you’re speaking directly to key decision-makers with highly relevant messaging. So, how do you execute an effective one-to-one ABM strategy? Let’s break it down.

Best Practices for Running a 1:1 ABM Campaign

Executing a successful one-to-one ABM campaign requires a strategic approach that prioritizes audience segmentation, targeted personalization, and seamless sales and marketing coordination.

1. Build the Right Audience

Audience building is key to any ABM campaign, but for one-to-one ABM, precision matters. Knowing exactly who’s engaging with your content helps ensure you’re targeting the right stakeholders within an account. This includes tracking clicks from emails, ad engagement, and intent signals.

Focus on the Buying Circle, Not Just Individuals:

  • Break larger accounts into smaller buying circles of 10-20 key stakeholders based on roles, interests, and decision-making influence.
  • Assign contacts to a Buying Circle group to track engagement and refine targeting.
  • Leverage account intent data to prioritize the right accounts based on their readiness to buy.

💡 Pro tip: Many teams use a combination of first-party data, intent-based signals, CRM insights, and external sales engagement information to refine their audience targeting before launching a campaign.

2. Prioritize the Right Channels

Choosing the right channels is essential for maximizing engagement in one-to-one ABM campaigns. A successful one-to-one ABM strategy prioritizes precision, personalization, and omnichannel touchpoints

Best Channels for 1:1 ABM:

  • Programmatic Advertising: Delivers targeted, account-specific messaging at scale, ensuring visibility across the buyer’s journey
  • Direct Email and Outreach: Enables highly personalized messaging at the right time, strengthening relationships with key contacts
  • LinkedIn and Social Engagement: Supports brand awareness and soft engagement but should be combined with more direct channels

💡 Pro Tip: Use programmatic advertising for granular analytics and deeper engagement insights, refining targeting and messaging strategies over time.

Aligning Channels with Buying Circle Roles:

  • Decision-Makers: Programmatic ads and direct email with ROI-focused messaging
  • Champions: LinkedIn engagement and nurture emails that reinforce value
  • Influencers: Educational content and social proof through targeted ads

3. Personalize Messaging at Scale

One of the biggest challenges in ABM is personalizing at scale without overwhelming your sales team. With the right tools, you can automate personalization using AI-driven insights, ensuring each prospect receives a tailored experience.

Best Practices for Personalization:

  • Leverage engagement data (site visits, ad clicks, email interactions) to personalize outreach.
  • Use AI-powered recommendations to dynamically adjust messaging based on real-time data. 
  • Align with the sales team to ensure personalized messaging reflects recent conversations and buying intent.

💡 Pro Tip: Build sequential messaging across multiple touchpoints to create a cohesive journey for buying circle members.

Example of 1:1 Personalization:

  • First Touch: Programmatic ad with industry-specific value proposition
  • Follow-up: Personalized email referencing the ad engagement
  • Next Step: SDR outreach with tailored messaging based on behavioral signals.


4. Optimize and Iterate Based on Performance

One-to-one ABM isn’t a one-and-done approach. It requires continuous refinement based on performance data. 

Best Practices for Optimization:

  • Monitor engagement signals to adjust targeting and messaging.
  • Determine which messages resonate with which buying circle and adjust accordingly.
  • Align with sales insights to continuously refine outreach and improve conversion rates.
  • Track multi-channel performance to understand how each touchpoint influences pipeline progression.

💡 Pro Tip: Use A/B testing to refine messaging per persona—track engagement by role and optimize accordingly.

Metrics to Watch (And Why They Matter)

Tracking performance is critical to optimizing and proving the value of your 1:1 ABM campaigns. The right metrics help you understand what’s working, where to iterate, and how your efforts impact pipeline.

  • Ad Engagement Rates: Measure how effectively ads drive interaction
  • Email Response Rates: Identify which messages generate the most engagement
  • Pipeline Influence: Assess how one-to-one ABM contributes to revenue growth

1:1 ABM in Action: The Name Campaign

One way we’re pushing the boundaries of personalization at Propensity is through our Name Campaign—a fun, creative play that demonstrates just how hyper-personalized you can get. 

How It Works

We combine traditional targeting parameters such as job title, intent signals, and company fit with a unique layer of personalization: first names.

In this example, we targeted marketers within our ICP who also shared a common first name Jennifer. We created a specific campaign including:

  • Programmatic ads with their name in the creative 
  • A personalized landing page tailored to “Jennifer the marketer” 
  • Custom email and SDR follow-up referencing the name-based campaign
1:1 ABM example in Propensity

This combination of firmographic, behavioral, and psychographic data, plus the added “Name” layer, created an engaging, relevant experience that stood out from traditional B2B outreach.

💡Pro Tip: Name campaigns are an excellent way to stand out in crowded inboxes and feeds. They show off your brand personality while still delivering value, and they’re highly memorable—even shareable.
