Despite the rise of social media and ad platforms, email marketing is still one of the digital marketing channels with the highest return on investment. When used correctly, it offers a communication channel that the business owns directly and that is independent of algorithm changes.
In this article we cover what email marketing is, which campaign types it includes, how to set it up and what benefits it can bring to your business.
What Is Email Marketing?
Email marketing is a digital marketing method that lets businesses communicate directly with current or potential customers by email to build brand awareness, promote products or services and drive sales.
Unlike social media and search engine ads, email marketing runs on a channel the business owns. That gives you a direct and sustainable way to communicate that is independent of algorithm changes, rising ad costs or updates to platform rules. To see which campaign your newsletter links come from, you can tag your links with the UTM Link Builder tool.
Why Is Email Marketing Still Effective?
Many businesses focus on social media and ad channels and push email marketing to second place. But managed with the right strategy, email marketing offers these advantages:
- Direct reach: The message reaches the user’s inbox directly, without algorithmic filtering.
- Low cost: Wide audiences can usually be reached at lower cost than with ad channels.
- Personalization: Personalized messages can be sent to segments based on user behavior.
- Measurability: Data such as open rate, click rate and conversion can be tracked clearly.
- Automation: Automatic email sequences can be set up around specific triggers.

Email Marketing Campaign Types
Newsletter
Emails sent at regular intervals containing brand news, blog content or industry updates. The aim is usually to build a relationship and keep the brand remembered more than to sell.
Campaign Emails
Emails sent to announce a specific product, service or discount opportunity, with a clear call to action (CTA).
Welcome Series
An email sequence sent automatically to users who have just subscribed or signed up for the first time, introducing the brand. It is usually one of the campaign types with the highest open rate in email marketing.
Abandoned Cart Emails
Reminder emails sent to users who add products to their cart but do not complete the purchase. They can be quite effective for recovering conversions on e-commerce sites.
Re-engagement Emails
Emails sent to subscribers who haven’t opened or interacted with emails for a while, aiming to revive their interest.
Transactional Emails
Automatic emails tied to a user action, such as an order confirmation, shipping notification or password reset. Although they are not marketing-oriented, they are an important part of the brand experience.
How Do You Build an Email List?
An effective email marketing strategy starts with a list of high-quality, voluntary subscribers. Sends to purchased or permissionless lists both perform poorly and can damage brand credibility. To measure the long-term return of your email work, you can use the customer lifetime value (CLV) calculation.
Common list-building methods:
- Offering a newsletter signup form on the website
- Collecting emails in exchange for downloadable content (an ebook, a guide)
- Asking for a subscription in return for a discount code on the first purchase
- Offering a subscription option on event or registration forms
- Running subscription campaigns on social media
In every case the user’s explicit consent must be obtained, and an unsubscribe option must be easy to find in every email.
How Is Email Marketing Measured?
| Metric | What it tells you |
|---|---|
| Open rate | What share of sent emails were opened |
| Click-through rate (CTR) | The rate of clicks on links in opened emails |
| Conversion rate | The rate of purchases/forms completed via email |
| Unsubscribe rate | The rate of users who leave the list after an email |
| Deliverability | The rate at which sent emails reach the inbox |
| List growth rate | The increase in subscriber count over time |
By tracking these metrics regularly, you can determine which subject lines, send times and content types perform better.
Segmentation and Personalization in Email Marketing
Instead of sending the same content to all subscribers, grouping users by their behavior (segmentation) can significantly increase the impact of email marketing. For advanced personalization, see our article hyper personalization.
Common segmentation criteria:
- Purchase history
- Website behavior (pages visited)
- Subscription date and engagement frequency
- Geographic location
- Interests or preferred product categories
Content prepared for segments usually produces higher open and conversion rates than general, non-personalized emails.
What Is Email Automation?
Email automation is the automatic sending of pre-prepared emails based on a specific trigger (signing up, adding an item to the cart, a certain date and so on).
Automation lets the marketing team deliver the right message to the right user at the right time without sending every email manually. Welcome series, abandoned cart reminders and birthday campaigns are among the most common automation examples.
Automation is also an important part of the marketing automation concept and is usually managed integrated with CRM systems.
How Do You Prepare Effective Email Content?
What matters is not only that the email is opened, but that it moves the user to act after opening. Effective email content usually has these elements:
- An attention-grabbing but not misleading subject line: The element that most affects the user’s decision to open the email.
- A short and clear message: The user should be able to understand the purpose of the email in the first few seconds.
- A single, distinct CTA: Guiding the user to one action works better than several competing calls to action.
- Design that fits the brand identity: Colors, fonts and visual language should be consistent with the brand’s identity on other channels.
- Mobile-friendly design: Most users read emails on mobile devices, so the design must look right on mobile too.
When preparing content, presenting information, tips or offers that give the user value in balance with sales-focused messages helps build a healthier relationship with long-term subscribers.
Send Timing and Frequency
“When” and “how often” you send is another important factor that directly affects performance in email marketing. Sending too often can cause users to unsubscribe, while sending too rarely can cause the brand to be forgotten.
Points to consider when setting timing and frequency:
- The general behavior habits of the target audience (work hours, weekends, evenings and so on)
- The best-performing time slots based on open and click rates of past campaigns
- Frequency that varies by campaign type (newsletters can be weekly, campaign announcements less frequent)
- Send frequency differentiated by user segment
Since the best timing can vary from industry to industry and even brand to brand, it should be determined over time through testing and measurement.
Legal Compliance in Email Marketing
Complying with the legal regulations on protecting user data while running email marketing is both a legal requirement and important for brand trust. Points to watch in general:
- Marketing emails should not be sent without clear and understandable consent (permission) from the user.
- The user should be told clearly for what purpose and how often emails will be sent.
- Every email should have an easily accessible unsubscribe link.
- User data should be stored securely and not shared with third parties without permission.
- Unsubscribe requests should be processed within a reasonable time.
These practices not only reduce legal risk but also strengthen users’ trust in the brand.
The Relationship Between Email Marketing and Other Channels
Email marketing produces stronger results when evaluated together with other digital marketing channels rather than alone. For example, a visitor brought to the site by a Google Ads or social media campaign can be turned into a long-term relationship with automation sequences after subscribing to the email list.
Likewise, communication built with the customer on WhatsApp can be used as a complementary channel to email marketing; for setting up a business account, you can read our guide WhatsApp Business account.

Why Is the Return on Email Marketing So High?
Email marketing generally offers the chance to reach wide audiences at lower cost than many other digital marketing channels. The main reasons are:
- Unlike ad platforms, you do not pay separately for every impression or click.
- You can reach your existing customer or subscriber base again and again; you do not need to “buy” a new audience for every campaign.
- Thanks to automation, an email sequence set up once can keep producing value for a long time.
- Segmentation and personalization allow highly relevant messages to be sent at low cost.
For these reasons, email marketing stands out as a channel with high return potential, especially for small and medium-sized businesses with a limited marketing budget.
Personalization with Segmentation Examples
It can help to make segmentation concrete with a few examples of how it works in practice:
| Segment | Example content approach |
|---|---|
| New subscribers | Brand introduction, most popular products/services, welcome discount |
| Frequent shoppers | Loyalty program, exclusive early access offers |
| Those who haven’t bought for a long time | Re-engagement campaign, “we miss you” message |
| Those interested in a specific category | New product or content suggestions for that category |
| Cart abandoners | Product reminder, a time-limited incentive if available |
Such segment-based approaches make communication that takes each group’s interest and need into account, instead of sending the same general message to all subscribers. As a result, both open and click rates and overall customer satisfaction can be positively affected.
Common Mistakes in Email Marketing
- Sending to purchased lists without user permission
- Sending emails too often or too rarely
- Using misleading subject lines that create inconsistency between the headline and the content
- Using email designs that are not mobile-friendly
- Hiding or making it hard to find the unsubscribe link
- Repeating the same strategy without tracking performance data
