Is Email Marketing Still More Effective Than Social Media? Surprising Truth

When mentioning online marketing today, people often immediately think of Facebook, Instagram, or TikTok. These platforms are flashy, eye-catching, and always “hot.” But few expect that something seemingly “archaic” like email is quietly delivering far higher effectiveness. Can you believe it? A study from Custora, a predictive analytics company, showed that the rate of customers acquired through email has increased 4-fold over the past four years, accounting for nearly 7% of total new customers. Meanwhile, Facebook is practically “powerless” in converting into revenue, and Twitter is merely a secondary channel.

Are you investing the majority of your budget and effort into social media while forgetting the “old radio” named email? This article will help you look at the big picture to see which marketing channel truly helps you achieve sustainable sales growth. It is not about arguing “which side is better,” but about using the right channel at the right time, in the right place, for the right goal.

Email marketing: The silent “machine” generating revenue

Custora surveyed thousands of businesses and found that customers coming from email have an 11% higher value than the average. They shop more, spend more, and are more loyal. Meanwhile, customers from Facebook are only at an average value, and those from Twitter are up to 23% lower. This shows that email not only attracts customers, but also attracts the right portrait of potential customers—those ready to “open their wallets.”

The observation by Simms Jenkins, CEO of BrightWave Marketing, previously cited in an article on SiteProNews, is very thought-provoking: “If you only had one bullet in your gun to make a sale, email should always be that bullet.” While social media is fantastic for engagement and community building, email is the channel that leads to the purchase action. Because email is a “permission-based” channel—recipients have proactively subscribed, they care about you, and they allow you to send messages to their private inbox. That permission is extremely precious, meaning you do not have to stalk or beg anyone.

Why email still “thrives” in the era of social media

Have you noticed that every morning when you wake up, before opening Facebook, you usually check your email right on your phone? That’s right, email is the number one activity people perform on smartphones. Thanks to the widespread use of smartphones, email is always “on duty,” right inside the customer's pocket. They open emails whenever they have free time: while waiting in line for coffee, on the bus, or during lunch breaks. On Facebook, constantly changing algorithms mean your posts might only be visible to a tiny fraction of your followers unless you pay.

Another major strength of email is its capability for personalization and segmentation. Instead of broadcasting one message to everyone as on social media, you can divide your email list into smaller groups based on interests, behaviors, and purchase history. An abandoned cart email sent to someone who viewed a product but hasn't bought it will generate direct revenue. Meanwhile, social media can only run ads for a lookalike audience group, but the message must still be much more general.

Effectiveness comparison: Email completely beats social media in revenue

Let's look at the numbers from Custora's research that many people overlook: Organic search brings in 16% of new customers—leading the way, but this is a long-term SEO channel. Email ranks second with 7%, while Facebook and Twitter account for only a tiny percentage. Regarding customer value, email customers are 11% more valuable than average. Facebook customers are at an average level, and Twitter customers are 23% lower. Therefore, when you need a quick sales campaign, email can generate revenue immediately, whereas social media is flashy but only suitable for brand building and engagement.

Furthermore, the cost of email marketing is much cheaper than social media advertising. Instead of paying for every impression or click, you only need to invest in an email sending platform (like Mailchimp, GetResponse) and maintain a clean subscriber list. If you have accurate data (voluntary subscribers, valid email addresses, good segmentation), the cost per customer will be extremely low. Imagine sending an email to 1,000 interested people ready to buy; the cost is almost zero, yet it can generate hundreds of millions in revenue. Social media can hardly be that effective.

Secrets to making email marketing truly effective in the new era

So how can you maximize the power of email? Based on experience from successful campaigns, you should keep the following in mind:

• Allow users to choose email frequency: Build a preference center where they can choose to receive emails daily, weekly, or only when there is a major promotion. This helps reduce the unsubscribe rate.
• Segment your list: Do not send the same content to everyone. Divide by interests, gender, geographic location, and purchasing behavior. Open rates and conversion rates will skyrocket.
• Optimize for mobile devices: 55% of emails today are opened on smartphones. If an email doesn't display nicely on a small screen, 70% of recipients will unsubscribe immediately. Therefore, use responsive design and concise subject lines.
• Distinctive tone of voice: Do not copy Facebook posts directly into emails. In emails, people want to receive offers, promotions, and specific value. On Facebook, they want emotional storytelling and connection. Understanding this, you will build the right experience for each channel.

Imagine a fashion brand. They use Instagram to showcase products, Facebook to host interactive minigames, but when they want to “close deals” over the weekend, they send an email offering a 20% discount code to their loyal customer list. The result? Hundreds of orders in just a few hours. That is the power of email.

Challenges and trends: Do not neglect email

Despite its effectiveness, email marketing also has its own challenges. One of them is maintaining list quality. If you buy a spam email list, the bounce rate will be high, and service providers may block your account. Instead, build your list by collecting emails at checkout: “Enter your email to get 10% off your next purchase.” This method is both legal and brings in truly interested customers.

A big mistake many businesses make is pouring all their energy into social media, leaving email to “die” in silence. They think email is obsolete, but in reality, it remains the channel with superior conversion rates. According to Jenkins, businesses that know how to systematically invest in email will be the winners in the customer acquisition race. Do not chase “new toys” and abandon an effective channel sitting right in front of your eyes.

Take action now: Don't miss out on opportunities from email

If you haven't started email marketing yet, today is the best time. You can start by collecting emails from website visitors, customers, or webinar attendees. Use a professional email marketing platform to manage and send automated emails. A/B test your email subject lines, measure open rates, click-through rates, and continuously improve.

And if you already have an existing email list, don't waste it. Create a welcome email campaign, a new product introduction email, or a special promotional email exclusively for subscribers. Remember, the only person you need to convince is someone who voluntarily left their email—that means they are already interested in you. Email is the bridge between you and your most potential customers.

So, it's time to review your marketing strategy. How much time are you spending polishing email content compared to updating images on Instagram? Are you neglecting a “gold mine” called email? Share your perspective in the comments section. We look forward to hearing your story!
