Effective email marketing isn’t just about what you send—it’s about who you’re sending it to, how you present the information and the experience you create for the person receiving it.
These 10 practical tips cover some of the biggest opportunities to strengthen your email marketing, from audience segmentation and sender reputation to testing, consistency and accessible design. Whether you’re sending a monthly newsletter or a one-time campaign, there’s something here you can put into practice right away.
1. Segment your audience — and tailor the message
Who you send to is just as important as what you send.
Sending the same blanket message to everyone can hurt both engagement and sender reputation. Segment audiences based on factors such as how they engage with your emails, their interests or other relevant contact data, and tailor your messaging accordingly. For example, you might adjust the frequency of your emails to a particular audience based on how they interact with your emails. Similarly, you might adjust the content or personalization of your emails based on characteristics of a group, such as campus location, major, year in school or interest in certain topics.
When possible, think beyond simply who is on the list and consider what that audience needs from this particular message.
2. Sender reputation is built over time
Email service providers evaluate the reputation of the domains and sending infrastructure used to send emails. That reputation is influenced by factors such as domain reputation, spam complaints, sending practices and recipient engagement. Consistently sending unwanted or irrelevant messages—or continuing to send to audiences that don’t engage—can negatively affect how email providers evaluate your mail.
It’s also important to understand the difference between delivery and deliverability.
A high delivery rate means the email was accepted by the recipient’s email service provider (e.g. Outlook, Gmail, Yahoo). It does not necessarily mean the message reached the inbox. Deliverability is about whether the message ultimately reaches the inbox rather than being filtered into spam or junk.
Audience engagement can play an important role in deliverability. Segmenting your audience, prioritizing engaged contacts and regularly reviewing or removing consistently unengaged contacts can help support a healthy sender reputation. Creating content that recipients find useful and want to engage with can also contribute to positive engagement over time.
3. Keep emails focused and easy to scan
More content isn’t necessarily better.
Focus on one to five key points — and sometimes, one is enough.
Use design to help readers quickly understand what’s important:
- Clear headings and hierarchy
- Strong calls to action and buttons
- Visual breaks and content blocks
- Concise copy
- Short blurbs that link to longer content, such as a blog post or webpage, rather than placing the entire article in the email
And remember: Don’t turn a flyer or print piece into an email.
Email is its own communication format. Use live text alongside images so the message remains accessible, readable and understandable when images don’t load.
4. Design for the device, not just the desktop
Always preview emails on desktop, mobile and tablet.
Mobile isn’t simply a smaller version of desktop. Content, font size, alignment, navigation and calls to action may need to be adjusted to create a good experience on smaller screens.
Even small design decisions can make a difference. For example, buttons can provide a better mobile experience than text links because they’re easier to tap.
5. Accessibility should be part of the design process
Accessibility shouldn’t be something we check only at the end of the email-building process. It should be considered from the beginning.
Use live text, meaningful alternative text and accessible design practices rather than relying on images to communicate the message.
A simple question to ask during your review:
“If the images didn’t load, would the recipient still understand the email?”
If the answer is no, consider what information can be communicated through live text or other accessible design elements.
6. Consistency matters
Establish a predictable sending cadence so subscribers know what to expect. Include the expected frequency in your welcome email or subscription description when possible. Avoid going silent for months and then sending multiple emails at once. Sporadic communication can make it harder to maintain subscriber engagement and may contribute to unsubscribes.
Email coordination is also important for organizations with multiple teams communicating with the same audiences. Where possible, coordinate email calendars across teams and departments to help prevent recipients from receiving a flood of messages at the same time.
7. Review before you send
A simple pre-send checklist can help catch mistakes before you hit Send.
- Send a test email—ideally to someone else for a second set of eyes
- Verify the audience and segmentation
- Review the subject line and preheader
- Preview desktop, mobile and tablet versions
- Check links and calls to action
- Review the email from the recipient’s perspective
- Make sure the most important takeaway is immediately clear
8. Let your data inform your strategy
Don’t judge an email’s performance based on a single metric. For example, a high open rate might indicate that your subject line resonated with your audience, but it doesn’t necessarily mean the email achieved its goal. Consider how recipients responded to the email as a whole and whether they took the action you intended.
Look for trends over time, including engagement, subscriber growth and performance across different audiences, email domains, time zones and seasons of the academic year.
Your data can help inform decisions about content, messaging, audience segmentation, sending cadence, calls to action and overall email strategy. The goal isn’t simply to collect metrics. It’s to use those metrics to understand what is working and where there may be opportunities to improve.
9. Test, learn and improve
A/B testing can help you make more informed decisions about what resonates with your audience. Rather than guessing what will work best, test one element at a time—such as a subject line, call to action, image or content approach—and compare the results.
Start with a clear question. What are you trying to learn, and what metric will help you answer it? Keep the test focused so you can better understand what influenced the results.
Over time, use what you learn to inform future emails. Testing isn’t about finding one formula that works every time—it’s about learning more about your audience and continually improving your approach.
10. Use automation strategically
Look for opportunities to automate repetitive or time-sensitive communications. If you’re sending a series of related emails, consider using automation rather than manually scheduling every message.
Automation can help create more timely, consistent communication while reducing repetitive work for email marketers. It can also help subscribers receive relevant messages based on where they are in the communication journey.
Automated welcome emails are one simple opportunity to consider. New subscribers are often highly engaged, making a welcome email a valuable way to establish the relationship, provide useful information and set expectations from the beginning.
One final takeaway
We’re still sending emails to people.
Technology can help us work more efficiently. Data can help us make better decisions. AI can help us work in new ways.
But none of that replaces the need to think about the person on the other end of the message.
Good email marketing combines data, technology and automation with thoughtful content, accessible design and an understanding of the recipient’s experience.
