E-commerce brands are feeling the pressure of declining email engagement rates. Once a reliable tool for reaching customers, email marketing has seen open rates plummet from an average of 25% to under 15% in just five years. In contrast, WhatsApp is emerging as a marketing powerhouse with open rates surpassing 65% and delivery rates above 90%. As e-commerce companies grapple with this revenue gap, many are making bold moves—shifting up to 30% of their email marketing budgets to WhatsApp. So, why are brands rethinking their marketing strategies, and how is WhatsApp emerging as the dominant player in the battle for consumer attention?

The Email Fatigue Crisis

Today’s consumers are drowning in an ocean of emails. On average, each person receives over 120 emails daily. This volume not only makes it harder for brands to stand out but also fosters what’s known as “email fatigue.” The result? Declining engagement across key e-commerce categories. As inboxes fill up, consumers are becoming increasingly selective about which emails to open, let alone engage with.

The situation is compounded by the rising cost of email acquisition and deliverability. With a steady increase in competition for inbox space, brands must spend more to maintain visibility. Data shows that email marketing ROI has declined by 22% over the last three years, signalling that traditional email marketing tactics are becoming less effective.

WhatsApp: From Support Channel to Revenue Engine

WhatsApp’s evolution from a customer service tool to a revenue-generating marketing platform has been nothing short of remarkable. Meta’s strategic investments in business capabilities, such as the WhatsApp Business API, have turned the platform into a robust channel for e-commerce brands. Unlike email, WhatsApp offers a direct line of communication with consumers, fostering a more personal and interactive experience.

Consider the case of Dot & Key, a leading skincare brand. Originally focused on email marketing, the company realised that the low engagement in email campaigns was limiting its growth. By shifting to an omnichannel strategy that incorporated WhatsApp, Dot & Key saw substantial improvements in open rates and customer interactions. This transition allowed the brand to enhance customer experience while driving revenue growth.

The Numbers Tell the Story

When comparing WhatsApp to email on key performance metrics, the numbers are clear:

Open Rates: WhatsApp boasts an impressive open rate of 65%, while email struggles to reach 15-20%.

Click-Through Rates: WhatsApp’s click-through rate is 35%, compared to email’s meagre 2–3%.

Conversion Rates: WhatsApp also leads with a conversion rate of 15%, while email hovers around 1-3%.

These metrics illustrate the growing gap between email and WhatsApp as marketing channels, providing a strong case for e-commerce brands to allocate more of their budgets to the latter.

Boosting Recovery Rates with WhatsApp

Abandoned carts have long been a challenge for e-commerce brands, with traditional email recovery rates typically ranging between 8% and 12%. However, WhatsApp has demonstrated a much higher recovery potential, with estimates ranging from 15% to 25%. When combined with email, this approach can push recovery rates to 28-35%.

This substantial difference in recovery rates can translate into a significant revenue impact. For example, a company generating $1 million in monthly sales could recover an additional $100,000–$200,000 in revenue simply by integrating WhatsApp into their abandoned cart strategy.

Personalisation Opportunities Beyond Email

While email has long been the go-to for personalisation, WhatsApp’s rich media capabilities offer far more engaging ways to interact with customers. Brands can send images, videos, and even product catalogues, creating an interactive experience that email simply can’t match. Furthermore, WhatsApp’s conversational commerce features allow brands to engage customers in real-time, answering questions, offering product recommendations, and facilitating immediate purchases—all within the app.

This level of interactivity is proving to be highly effective for product discovery. Research shows that 70% of consumers are more likely to buy products they discover through messaging apps like WhatsApp.

Smart Budget Allocation Strategy

As e-commerce brands look to optimise their marketing spending, finding the right channel mix is crucial. Studies suggest that a balanced approach, with 30to40% of the budget allocated to messaging apps like WhatsApp, can deliver the best results. Here’s an example of an optimal channel allocation breakdown:

Email: 50-60%

WhatsApp: 30-40%

SMS/Other Channels: 10%

Timing is also a key factor. Email may still be effective for delivering long-form content, product updates, or sales promotions, but WhatsApp shines when it comes to time-sensitive offers, customer service, and interactive product discovery.

Segmentation plays a critical role too. Research shows that younger consumers (18-34) are more likely to engage with WhatsApp campaigns, while older demographics may respond better to email or SMS. Tailoring your channel strategy to the preferences of different customer segments is crucial for maximising ROI.

The WhatsApp Evolution

In the future, it is evident that the use of messaging apps will continue to grow at an even faster pace. As WhatsApp keeps adding new features, such as chatbots powered by artificial intelligence, video calls, and improved analytics, e-commerce brands will have even more chances to interact with consumers in a dynamic and personalized manner.

Experts anticipate that by 2026, messaging apps will become the primary focus of marketing budgets, with WhatsApp expected to take the lead. Brands that prioritise investing in conversational commerce early on will gain a competitive edge as more consumers adopt this platform.
