Everything you need to know about email marketing: what it is, how it works, and why it's more cost-effective than social media and paid ads.
More and more businesses, large and small, rely on email marketing, and today it’s hard to find a company that doesn’t use it to create engaging, effective communications.
What is email marketing? Email marketing is a type of direct marketing that uses email to communicate with a specific audience, with the goal of building relationships, promoting products or services, and driving sales. It’s one of the most cost-effective digital marketing channels, with an average ROI of $36 to $42 for every $1 spent.
If you’re wondering how email marketing works or what its advantages are, you’re in the right place.
Definition of email marketing: what it is and why it works
Email marketing is a type of direct marketing, meaning it reaches customers without intermediaries, based on using emails to connect with a specific target audience. That’s why it’s also called DEM marketing, or Direct Email Marketing.
It’s one of the most powerful channels available to companies and freelancers alike, because it allows you to build a direct, personalized relationship with your customer.
This means that, with email marketing, you’re not just talking to a generic crowd. You can set up emails that speak to each subscriber as a specific person, someone who chose to receive your communications. That makes all the difference: it helps you build loyalty and push the recipient toward purchasing your product or service, an important goal if you want to grow your business.
How does email marketing work? Everything you need to know
The mechanism behind email marketing is fairly simple, but to make it work you need to understand each step.
The starting point is collecting a contact list (also called a mailing list): a group of people who have given explicit consent to receive your communications. You can collect new contacts through a form on your website, a landing page, an event, or an incentive like free content. Without a quality list, no campaign can work: it’s the starting point of everything.
Once you’ve collected contacts for your list, it’s time to create the message.
Choose your email template and personalize it, define the subject line and sender.
Thanks to personalized fields, you can include the recipient’s name or other specific data in every email, and this personalization isn’t a minor detail: emails with a personalized subject line generate open rates up to 50% higher than generic ones.
Once everything is ready, you can send your campaign, right away or at a scheduled time, to your entire list or just a specific segment, based on interests or past behavior.
Once your campaign is sent, you can analyze the results: how many people opened the email, how many clicked, how many unsubscribed. This data lets you improve every future campaign, until you find the formula that works for your audience.
Email categories: 4 types of email marketing and their differences
Not all marketing emails are the same, and understanding the difference is key to using the right tool at the right time.
A newsletter is a periodic send of informational content or updates to a list of subscribers. Its goal isn’t direct selling, but building an ongoing relationship with your audience over time.
DEM (Direct Email Marketing) is instead a commercial communication with a specific goal: promoting a product, announcing an offer, or inviting recipients to an event.
Then there are transactional emails (order confirmations, password resets, payment receipts), which are automatically triggered by a user’s action and have extremely high open rates, precisely because the user is expecting them.
And finally, email marketing automation: automated email sequences that trigger based on user behavior, like a welcome message for new subscribers or a reminder for someone who abandoned their cart. You set them up once, and they run on their own.
What are the main advantages of email marketing (and how they can grow your business)
Email marketing is an extremely powerful tool that guarantees numerous advantages to those who use it. Let’s discover them together!
1. High return on investment.
The first, and most important, is ROI. Email marketing generates an average of $36 to $42 for every $1 invested, the highest return of any digital marketing channel. For comparison: paid search advertising returns about $2 for every $1 spent. There’s no contest.
2. Your contact list belongs to you.
Another advantage that’s often underestimated is channel ownership. Unlike other channels, your email list belongs to you: no algorithm decides who sees your messages, and no platform can limit your reach overnight. It’s no coincidence that 4 out of 5 marketers say they would give up social media before giving up email marketing.
3. Easy to use, accessible to everyone.
4. Personalized content for every subscriber.
Another major advantage of email marketing is personalization: every recipient can receive a message tailored specifically to them, with their name, their interests, their purchasing habits. Instead of writing “Dear Customer,” you can greet the person by name, and this completely changes how the message is perceived.
5. Measurable (and optimizable) results.
Email marketing performance is measurable with precision: open rate, clicks, conversions, unsubscribes. You know exactly what’s working and what isn’t, and you can optimize every campaign based on real data, not guesswork.
6. No manual work, thanks to automation.
Finally, there’s automation. With automated sequences, you can guide your customer through their entire purchase journey without manual work: a welcome for new subscribers, a reminder for those who haven’t completed their purchase, a thank-you after the sale. Sending a sequence of three abandoned cart emails, for example, generates 69% more orders than a single reminder.
Limits and disadvantages of email marketing
Like any tool, email marketing has its limitations, and being aware of them is just as important as knowing its advantages. No channel is perfect, and understanding where email marketing can fall short helps you avoid common mistakes and get the most out of your campaigns.
1. Spam risk.
2. Requires a quality list.
3. Inbox overload.
People receive dozens of emails every day. To stand out, your messages need to be relevant, well-written, and sent at the right frequency. Otherwise they risk being ignored or triggering unsubscribes.
4. Deliverability depends on reputation.
These are real email marketing risks, but they’re entirely manageable with the right practices and a professional platform.
