Email Marketing guide: What to Review Before Getting Started

When someone enters this field without much experience, they often think email marketing is simply about sending emails. But it’s not just that. In reality, it’s about using email with a specific goal—whether that’s selling, getting a response, reactivating customers, or staying in touch with them.

The difference between just sending messages and working the channel with intention lies in the results. It’s not enough to send an email. That message needs to arrive properly, get opened, and provide something useful to the recipient.

Email remains an important channel. It’s estimated that the daily volume of emails will exceed 408 billion per day by 2027. On top of that, many industry statistics still place its average return at around $36 for every dollar invested. This doesn’t mean every campaign will work, but it does show that, when done properly, it remains a profitable and serious channel.

There’s another practical point for beginners: most emails are checked on mobile devices. Around 64% of people primarily check email on their phones, and 93% check their inbox daily. That’s why if a message looks bad on mobile or is hard to understand, it already starts at a clear disadvantage.

For this reason, before thinking about campaigns or platforms, it’s more sensible to first understand the factors that truly influence results.

It’s also important to accept something from the beginning: in email marketing, solid results rarely come from improvisation. Often, a campaign fails not because the channel doesn’t work, but because it’s launched too early—without reviewing the list, without a clear value proposition, or without defining the expected action from the recipient. These initial mistakes are quite common and often lead to wrong conclusions. Instead of assuming the problem is email itself, it’s more reasonable to review whether the launch strategy was properly planned from the start.

Using a Platform is Not Enough in Email Marketing

One of the most common beginner mistakes is believing everything depends on the tool. Many people think that by using platforms like Mailchimp, Brevo, or others, most of the work is already done. That’s not how it works.

Several elements come into play in a campaign: contact quality, message content, email design, subject line, and whether the email actually reaches the inbox or ends up in spam.

Put simply: you can have a great message, but if you send it to the wrong people—or it doesn’t even reach them properly—the result will likely be poor.

Another key point is that platforms can make work easier, but they don’t decide segmentation, message approach, or timing. They automate tasks, but they don’t replace judgment. That’s why it’s more worthwhile to understand campaign logic than to obsess over comparing nearly identical tools.

Which Metrics Matter to Avoid Guesswork

This is one of the most important parts for beginners. Campaigns are often judged with vague ideas like “it worked well” or “it didn’t.” That’s not helpful if you want to improve.

What really helps is focusing on simple data:

• If many people open the email but few click, the issue is likely the content or call to action.
• If there are very few opens, the problem is usually the subject line, sender, or trust level.
• If there are too many bounces, the issue is typically the contact list.

It’s also useful to look at general industry benchmarks. For example, only 27.62% of campaigns include personalization in the subject or body. That shows there’s still a lot of room for improvement in something as basic as adapting the message to each recipient.

As a reference, average open rates are around 16.49%, and click rates around 1.03%. These aren’t universal, but they help identify whether a campaign is performing reasonably well or needs improvement.

Another key idea: don’t analyze metrics in isolation. A good open rate doesn’t always mean success, and a low click rate doesn’t always mean poor copy. Sometimes the issue is the offer, audience fit, or timing. Context matters.

Email Databases Matter More Than They Seem

Campaign performance doesn’t depend only on text or design—it also depends heavily on who receives the message.

If a company uses an outdated, poorly segmented, or invalid email list, the result will usually be high bounce rates, low opens, and weak performance.

That’s why email marketing databases are more important than many think. It’s not about collecting many emails—it’s about having useful, current, and well-organized contacts.

A poor database can ruin even a good campaign. A well-structured one, however, improves decision-making from the start.

Segmentation plays a major role here. Writing to a new contact is not the same as writing to someone familiar with the brand. Sending the same message to different profiles rarely works well. The better the segmentation, the better the content fit—and the better the results.

Platforms Aren’t Everything: Other Useful Resources

Another common mistake is thinking free email marketing tools are just sending platforms. In reality, there are other useful resources:

• Email validation tools to check if addresses are still valid
• Spam testing tools to detect issues before sending
• Design tools to improve visual appearance, especially on mobile

Starting well doesn’t depend only on choosing a platform, but on understanding what each tool is for. It’s also important to monitor domain reputation and inbox delivery, something Google recommends through tools like Postmaster Tools.

A simple example: if a company has an old email list, it’s more logical to verify it first rather than launching a campaign blindly.

It is also worth remembering that the message itself matters a lot. In professional email marketing, a clear subject line, an easy-to-scan structure, and a single call to action usually work better than a scattered or overloaded email, as can be seen both in specialized guides and in recommendations from industry platforms such as Mailchimp.

What Decisions Should Beginners Make?

If a company has few contacts and is just getting started, it can begin with simple campaigns and free email marketing tools.

If the list is old or has been built from different sources, the first step should be to review the quality of those email marketing databases.

If emails are being sent but hardly anyone opens them, it’s worth reviewing the subject line, the sender, and the level of trust the message conveys.

And if emails are opened but don’t generate clicks or responses, then it’s time to review the content, the design, and the clarity of the message.

Seen this way, everything stops feeling overly technical or distant. It becomes much simpler: identify what’s failing, fix it, and measure again. And if you want to go deeper into the more strategic side, it’s also useful to rely on resources that explain how to define objectives, improve segmentation, and measure more effectively, such as this email marketing guide by Brekiadata.

In reality, getting started well usually comes down to making a few decisions—but the right ones. Defining a clear objective, reviewing database quality, preparing a clear message, and measuring the basics already makes a significant difference compared to launching unstructured campaigns. There’s no need to start with a complex strategy to get useful insights. In many cases, the most effective approach is to begin with something simple, see how the audience responds, and improve from there.

Building an Effective Strategy

This guide exists for a reason: to help understand the essentials before moving into more advanced strategies.

Email marketing is not just about sending emails—it’s about making better decisions based on simple data.

Knowing whether emails are opened, clicked, delivered properly, and sent to quality databases completely changes how campaigns are approached.

And when a company understands this from the beginning, it already starts with a much stronger foundation. For those who want to dive deeper step by step and put all these concepts into practice, it can be useful to rely on a well-structured email marketing guide from the start.
