Turn Your Retainer Into a Revenue Growth Engine

Most eCommerce agencies have already perfected the fundamentals of lifecycle marketing. Welcome journeys, browse abandonment, cart recovery, post-purchase flows. However,  they're no longer differentiators, they're table stakes.

The bigger challenge today isn't building more automations or endlessly optimizing existing flows, it's getting more qualified shoppers into those journeys in the first place.

That's becoming increasingly difficult. Rising acquisition costs, longer paths to purchase, and anonymous website traffic all limit the number of customers brands can actually engage through their owned marketing channels. Even the most sophisticated email and SMS programs can only perform as well as the audience entering them. This presents an opportunity for agencies.

By helping clients recognize more website visitors and activate richer behavioral data, agencies can unlock measurable revenue gains while creating entirely new strategic services that strengthen long-term retainers.

With BFCM approaching, there's no better time to have those conversations.

Why Lifecycle Marketing Eventually Reaches a Ceiling

Most brands have invested heavily in lifecycle marketing over the last few years. Their welcome series is live. Cart abandonment performs well. Browse abandonment has been refined through multiple rounds of testing. Yet many programs eventually plateau.

The reason isn't necessarily poor execution, it's limited visibility. As much as 95% of website traffic remains anonymous, meaning the majority of high-intent visitors never become eligible for the personalized journeys brands have spent years building. At the same time, customer acquisition costs continue to rise, conversion growth slows, and the time between first visit and first purchase continues to lengthen.

The result is simple: agencies are often being asked to generate more revenue from the same limited audience.

Instead of continually refining existing automations, agencies can create significantly more value by helping clients expand the number of shoppers those journeys actually reach.

Five Ways Agencies Can Expand Their Retainers

Identity-driven marketing creates opportunities that extend well beyond implementation. It opens the door to ongoing strategic services that clients increasingly need as they prepare for peak season.

1. Build More Valuable Audience Segments

Better customer intelligence creates better segmentation. With richer behavioral data available inside existing ESPs, agencies can build entirely new audiences that support more relevant messaging and more sophisticated lifecycle programs.

Examples include:

• High-intent browsers
• Category abandoners
• Frequent visitors
• Returning anonymous shoppers
• Recently identified customers
• High-value product viewers

These audiences create opportunities for ongoing optimization work rather than one-time implementation projects.

2. Launch Additional Revenue-Generating Journeys

Most retailers still rely on a relatively small number of lifecycle automations. With richer behavioral triggers available, agencies can introduce new journeys that respond to customer intent throughout the buying process, including:

• AI-powered browse, category, product and cart abandonment journeys
• Price drop notifications
• Low inventory alerts
• Back-in-stock messaging
• Product and catalogue engagement journeys

Rather than replacing existing flows, these journeys expand the moments where brands can engage customers with relevant, timely messaging.

3. Deliver Richer Customer Profiles

Customer profiles shouldn't stop evolving once someone subscribes. Behavioral intelligence can continue enriching profiles with additional engagement signals and longer lookback windows, giving agencies more data to personalize campaigns across email and SMS.

That means smarter segmentation, more relevant recommendations, and campaigns that reflect what customers are actually interested in, not simply what they purchased months ago.

4. Extend Personalization Beyond Owned Channels

Identity shouldn't end with email. Enriched customer profiles can also strengthen broader marketing strategies by improving audience activation across paid media.

Agencies can help clients:

• Improve Meta retargeting audiences
• Build smarter suppression lists
• Sync higher-quality audiences across platforms
• Deliver more consistent cross-channel personalization

This positions agencies as strategic growth partners rather than execution-only service providers.

5. Introduce Ongoing Identity Optimization Services

Perhaps the biggest opportunity isn't implementation, it's continuous optimization. Identity resolution shouldn't be viewed as a one-time project. Like deliverability, segmentation or CRO, it benefits from regular review and refinement.

Agencies can build recurring services around:

• Identity resolution audits to benchmark anonymous versus known traffic
• Prioritizing high-intent behavioral triggers
• Flow refreshes based on new behavioral signals
• Segment and profile optimization
• Reachable audience reporting
• Quarterly strategic reviews
  

These services naturally fit existing retainers while creating measurable business value for clients.

Why this matters before BFCM

Peak season amplifies every missed opportunity. The brands that perform best during BFCM aren't necessarily sending more campaigns, they're reaching more high-intent shoppers with more relevant messaging.

Product views, browse sessions and abandoned carts all increase dramatically during holiday shopping periods. If those visitors remain anonymous, brands lose valuable opportunities to recover revenue through their existing lifecycle programs. When real-time identity and behavioral intelligence feed directly into platforms like Klaviyo, agencies can help clients:

• Capture more abandoned carts inside existing automation
• Reach more product viewers with personalized follow-up
• Re-engage previous visitors using longer behavioral lookback windows
• Convert more first-time buyers into repeat customers

Importantly, none of this requires rebuilding an existing email program. The creative, orchestration and sending remain inside the client's existing ESP. The opportunity lies in expanding who qualifies for those journeys through richer identity and behavioral data.

Turn holiday success into long-term agency growth

Strong BFCM performance often shapes year-end client conversations. When agencies can clearly demonstrate incremental revenue, improved audience reach, stronger segmentation and better-performing lifecycle campaigns, those conversations naturally evolve from campaign performance into long-term strategic partnerships.

Instead of wrapping up after peak season, agencies can continue delivering value through:

• Monthly lifecycle optimization
• Quarterly segmentation reviews
• New journey launches
• Identity performance reporting
• Reachable audience expansion
• Continuous testing and experimentation

The result is a stronger, more consultative retainer built around measurable business outcomes rather than hours alone.

Final thoughts

Agencies don't need to reinvent their lifecycle strategy ahead of BFCM. Most clients already have the core customer journeys in place. The opportunity is expanding the audience those journeys can reach.

By combining identity resolution with real-time behavioral intelligence, agencies can help clients recognize more shoppers, trigger more relevant customer journeys, and recover revenue that would otherwise remain invisible, all while creating new opportunities for strategic services and longer-term retainers.

As peak season approaches, the agencies that focus on audience expansion, not just flow optimization will be best positioned to deliver stronger client results and sustainable business growth long after BFCM has ended.
