E-commerce Businesses Are Spending Money On Ads While Their Emails Gather Dust

Acquiring new customers has only become more costly over the past few years, with a new customer costing 50 percent more in the last five years. HubSpot reports that email marketing for e-commerce businesses are heavily investing in paid ads on Google, Facebook, Instagram, and TikTok, but their marketing ROI continues to diminish.
These brands pay almost zero attention towards email marketing, a channel that provides an average ROI of 42:1. Instead, they spend thousands on ads to acquire one-time buyers instead of cultivating loyal customers through email engagement.
The Opportunity Cost From Using Email Less Than Possible
This is what happens when emails are neglected:
- Weak Customer Engagement: Engaging customers is already an uphill task, and only 20 percent of them come back for seconds without any form of engagement.
- Low Customer Engagement: According to reports, 70% of customers shopping online have left a purchase halfway.
- Inefficient Use of Email Lists: Emails are collected, but nurturing leads is where e-commerce businesses seem to lose the plot.
If your business is facing these issues, you are undisputedly losing revenue that is already within your grasp.

Your Competitors Are Already Winning With Email
It’s no secret large brands and firms have already turned a profit. This is why smaller smart brands are intricately planning strategies and using email marketing to earn ROI without spending on ads.
How Amazon Masters Email Marketing
Amazon has mastered using emails to market their products. This plays a big role in their success over their competitors and advancement towards brand dominance . Let’s take a look at how Amazon achieves mastery over ecommerce with emails:
- Personalized Suggestions: Amazon increases it’s conversion rate by 35% when it sends emails of suggestions to users based on their purchase history and browsing.
- Cart Recovery: They employ a sequence of reminder emails to recapture lost sales by enticing customers back.
- Customer Re-engagement: Long time no see customers are sent targeted emails containing discounts or product updates which ultimately reduces churn.
Amazon, a giant in the E-commerce world relies heavily on emails. If this is the case, why don’t other businesses follow suit?
Another example? Brands that are direct to consumer like Nomad, who sell accessories, claimed to gain 20% of their revenue from emails sent such as welcome emails, abandoned cart messages, and post purchase follow ups.
Not convinced? Klaviyo stats state e-commerce businesses that do apply email marketing vs those who don’t results in 30% repeat purchases increment.
If no convincing, the data stands clear. If you are not using emails strategically in your business, don’t be surprised when you hand your competitors revenue fall into the wrong hands.
