Sending email messages feels simple: open your email, click “compose,” write, and click “send.” When you’re sending an email to a coworker or a friend, sure, it is easy to just send an email.
Email is a specialized skill. It’s a lot different from your personal inbox. This is because there is a lot of technical groundwork that needs to happen before you ever type a subject line.

What Is Email Marketing
Email marketing is a fantastic channel for nurturing leads and building long-term customer relationships. But sending effective marketing emails is far more complex than just typing a message in Gmail or Outlook. It involves data analysis, ongoing maintenance, technical setup, and audience management.
You’ll need to work with specialized Email Service Providers (ESPs) or a Customer Relationship Management (CRM) solution that includes email marketing, like Mailchimp, ActiveCampaign, or Brevo. These platforms help you manage the processes required to ensure your emails reach the right people. As a bonus, CRMs also help you manage your leads and customers at every step in the sales funnel.
Email is hard. Sending emails incorrectly can harm your brand, erode customer trust, and potentially lead to serious legal consequences under regulations such as CAN-SPAM and GDPR. For this reason, and more, it’s best to work with an expert.
A Little Nudge: Building your email list with permission-based methods and maintaining clean data are foundational to a successful email marketing strategy.
The Power of Clean Data
Behind every successful email campaign is a foundation of clean, accurate data. This means having up-to-date, relevant subscriber information such as names, user preferences, and engagement behaviors. Data is what allows for the personalization and relevant content that customers expect.
Clean data allows you to build a robust automation strategy by segmenting your audience into specific groups. Grouping your audience based on their preferences and behaviors leads to highly targeted messages. This level of personalization dramatically increases engagement and improves your return on investment. Email marketing has an incredible ROI of up to 36:1. For every dollar spent, companies report a return of $10 to $36.
Data Privacy Laws and Their Impact
Understanding data privacy laws is a necessary part of email marketing. Today, various regulations govern how you can collect, store, and utilize personal data for email marketing:
- GDPR (General Data Protection Regulation – European Union): This comprehensive EU regulation is far stricter, generally requiring explicit, unambiguous consent before sending marketing emails to individuals within the European Union. Unlike the CAN-SPAM Act, GDPR is an “opt-in” law.
- CAN-SPAM Act (U.S.): This U.S. law sets rules for commercial email, including requirements for honest sender information, a clear opt-out mechanism, and a valid physical postal address. It’s more of an “opt-out” compliance law.
- CASL (Canada’s Anti-Spam Legislation): Canada’s law also emphasizes consent, often requiring express permission, though it permits implied consent under specific, time-limited conditions.
While GDPR is an overarching EU regulation, individual member states often have their own specific laws that apply as well. This creates a complex patchwork of requirements, and getting it wrong can lead to significant penalties .
A Little Nudge: Under GDPR, it doesn’t matter how big or small a business is; you must get permission to send marketing emails from users and provide them with a link to your Privacy Policy.
We highly recommend you work with a compliance expert or consult legal counsel to ensure your practices are fully compliant.
Writing for Engagement
The core purpose of most marketing emails is to drive users to do something. Whether it’s clicking a link, making a purchase, or signing up for an event, your email needs to clearly guide them to the next step.
For many action-oriented marketing emails like promotions or event announcements, scannable and direct copy is often the most effective strategy. Getting straight to the point increases the likelihood that your audience will read your call to action and click through.
Newsletters, however, often serve a different purpose. They tend to be longer because their primary goal is usually to educate, inform, or build community, rather than to promote or sell directly. In these cases, longer-form content provides more value and context.
Email for Everyone
Your email campaigns should be designed for everyone. According to the World Health Organization, 1 in 6 people has some form of disability. By ignoring email accessibility, you may be excluding a significant portion of your audience and missing valuable connections.
Image-only emails, while commonly used, are also a common mistake. They often fail for accessibility because:
- Invisible to screen readers
- May load slowly or not at all over poor internet connections
- Rarely optimized for mobile devices
- Difficult to read for neurodivergent individuals, people who are color blind, and older people
A Little Nudge: We hear you, designers. While centered text can be beautiful, readability and accessibility should always be the priority.
Why Emails Look Different Everywhere
It is a common frustration to create a beautiful email, only to find it looks completely different depending on where it’s opened. Various email clients interpret HTML and CSS code differently. The type of device, the operating system, the web browser, and the mail app itself can cause emails to appear differently from what you actually created.
Consistently rendering emails is an advanced skill that requires coding knowledge and specialized tools to preview and test across various email clients. Even with the skills and tools, some things will always look a little different. The most common rendering issue is the typeface actually displayed to the end user. Another common struggle is making emails look the same in both light and dark modes.
AI in Email Marketing
Generative AI is rapidly impacting every corner of marketing, and email is no exception. AI can assist with tasks such as generating subject lines, optimizing send times, and suggesting content variations and audience segments. Some systems even have built-in AI that can help create emails and user journeys.
However, marketing can’t be effective with AI alone. Your brand’s unique voice and the ethical judgment required for responsible marketing are inherently human. AI can enhance your capacity, but it doesn’t eliminate the need for humans.
Conclusion
There is a lot to understand about email marketing. It goes far beyond simply composing a message; it involves technical setup, data analysis, creating content for action and accessibility, understanding how messages render, and when to use AI as a tool.
Getting the best results and avoiding costly mistakes requires both creativity and technical expertise. For small businesses, managing these moving parts can be overwhelming and time-consuming.
