Email marketing continues to be one of the highest ROI marketing strategies, especially for small to mid-sized businesses (SMBs) where marketing budgets tend to be limited. According to Forbes email marketing statistics, email generates an average return of $36 for every $1 spent—higher than any other digital channel. For CEOs, business owners, and marketing leaders, mastering best practices in email marketing isn’t just a “nice to have”—it’s a direct path to growth, customer retention, and measurable revenue impact.
At Stratos Marketing Group, we’ve seen the gamut of email campaigns. Done poorly, emails become inbox clutter. Done well, they become a scalable sales engine. Here are the best practices for email campaigns that our Denver-based agency Stratos Marketing Group recommends for small to mid-sized businesses.
1. Start with Strategy, Not Just Sending
Why is strategy more important than volume in email campaigns?
At Stratos Marketing Group, we’ve found that blasting generic emails may temporarily increase reach, but it usually damages engagement long-term. A thoughtful, data-driven email marketing strategy ensures that every message serves a specific purpose and aligns with your broader business goals, whether that’s generating qualified leads, nurturing high-value prospects, or upselling loyal customers.
Without strategy, the best-designed campaigns can fall flat. Successful small and mid-sized businesses focus on why and who before worrying about how many. That means defining measurable objectives, segmenting audiences based on customer behavior, and creating content that meets people where they are in the buying journey.
Think of it this way: email isn’t just a communication tool. It’s an ongoing conversation with your customers. Strategic planning allows you to deliver timely, relevant, and value-driven messages that strengthen relationships rather than overwhelm inboxes. When done right, a strong strategy not only boosts open and click-through rates but also builds long-term trust and brand loyalty—something no amount of “send more” can replace.
2. Segment Your Audience
How does email segmentation increase ROI?
Segmentation is one of the most powerful levers in email marketing strategy—and one that too many small and mid-sized businesses overlook. Instead of treating your contact list as a one-size-fits-all audience, segmentation lets you tailor messages based on meaningful criteria such as industry, behavior, demographics, purchase history, or stage in the buying journey. The result? Campaigns that feel personal, not generic.
Why does this matter so much? Because relevance drives response. When people receive emails that actually reflect their needs and timing, they’re far more likely to open, click, and convert. In fact, according to Mailchimp research, segmented campaigns achieve click rates that are roughly 100% higher than non-segmented ones. That means every message you send has double the potential impact—without increasing your email volume.
At Stratos Marketing Group, we’ve seen how smart segmentation transforms performance. For example, an audience segmented by engagement level might receive different messaging—reactivation offers for inactive contacts and value-driven updates for your most loyal customers. Similarly, B2B campaigns can segment by industry vertical or decision-maker role, allowing you to deliver insights that truly resonate.
Effective segmentation isn’t just a technical exercise—it’s a mindset shift. It’s about treating your email list as a collection of individual relationships, not just addresses. When you segment with intention and align each group’s needs with your business goals, you turn simple broadcasts into meaningful conversations—and that’s where real ROI begins.
3. Invest in Quality Content and Design
What makes an email stand out in a crowded inbox?
Strong subject lines and compelling design win attention. But, based on what we’ve seen at Stratos Marketing Group, content is equally critical —decision-makers want value, not fluff.
- Keep copy scannable (short paragraphs and bullets).
- Prioritize mobile-first design—more than 50% of emails are read on phones.
- Use clear CTAs and whitespace to guide the reader.
Beyond layout and structure, great content connects emotionally and intellectually. The best-performing campaigns speak to both the reader’s goals and their challenges, offering insight, inspiration, or practical help in just a few lines. A clean, well-branded design reinforces credibility, while concise, benefit-focused messaging builds trust. Whether you’re sharing thought leadership, announcing a new service, or following up on a lead, aim for clarity and authenticity over cleverness. Consistent quality content not only earns higher engagement but also positions your brand as a trusted source in your customer’s inbox.
4. Personalization Beyond “First Name”
How can personalization increase conversions?
True personalization is about context and relevance, not just inserting a name into the subject line. For example, a CFO reading your email wants insights into ROI, while a marketing director may prefer case studies or tactical tips. Personalization builds trust because it shows you understand your audience’s priorities—and that you’ve taken the time to tailor your communication to them.
When content feels relevant, recipients are more likely to engage, click, and convert. Over time, this approach fosters stronger relationships and keeps your brand top of mind when it’s time to make a buying decision.
Practical personalization includes:
- Recommending related services based on past purchases.
- Sending industry- or role-specific content.
- Triggering campaigns based on subscriber behavior.
- Adjusting tone and messaging based on engagement history (for example active vs. dormant subscribers).
- Aligning timing and frequency with each contact’s preferences to reduce unsubscribes and increase relevance.
At its core, personalization is about empathy. By connecting your message to what each audience segment values most, your campaigns feel less like marketing and more like a meaningful conversation. That’s the difference between being opened once and being trusted long-term.
5. Timing and Frequency Matter
How often should businesses send marketing emails?
There’s no universal “perfect send time,” but testing will reveal what works best for your audience. For many B2B SMBs, mid-week mornings still tend to perform well as professionals are in planning mode. However, B2C brands often see stronger engagement in the evenings or on weekends—times when customers are more relaxed and open to shopping, booking services, or reading lifestyle content. The ideal schedule depends on your audience’s habits and the type of value your emails deliver.
Most small and mid-sized businesses find success with one to four campaigns per month, balancing visibility with audience fatigue. What matters most isn’t just how often you send, but how reliably you show up. At Stratos Marketing Group, we’ve found that the key is consistency—training subscribers to expect relevant, useful communications at predictable intervals.
Consistency also supports deliverability and brand recognition. When subscribers regularly open your emails, inbox providers are more likely to classify your messages as valuable rather than promotional clutter. Over time, steady, strategic sending helps you build a rhythm your audience looks forward to—turning each send into an opportunity to reinforce your brand’s credibility and expertise.
6. Measure, Refine, Repeat
Why is A/B testing important for email campaigns?
Email isn’t “set it and forget it.” Track key performance indicators like open rates, click-throughs, and conversions, then refine based on what the data tells you. Even simple, small changes—like subject line wording—can improve engagement by double digits.
You don’t need an advanced analytics team to make smart, data-informed decisions. Most email platforms—like Mailchimp, Constant Contact, and HubSpot—offer built-in reporting tools that make it easy to see what’s working and where to improve. Start small: review which subject lines get the most opens, what times of day deliver higher engagement, or which links drive the most clicks. These are easy insights that can quickly lead to better performance.
At Stratos Marketing Group, we remind clients that steady improvement beats perfection. You don’t have to overhaul your entire email strategy to see real results. Just identify one or two metrics to focus on each month. Celebrate those small wins, learn from the data, and keep building. Over time, those incremental refinements add up to measurable, lasting growth.
In addition, benchmarking your results is a smart way to measure progress and identify opportunities. Comparing your metrics—like open rates, click-throughs, and unsubscribe rates—to industry averages helps you understand whether your campaigns are over- or underperforming. But some of the most valuable benchmarks come from your own data. Tracking trends over time—such as month-over-month open rates or improvements in click-throughs after a design change—helps you set goals and refine future campaigns based on what works best for your unique audience.
7. Stay Compliant, Build Trust
What happens if a business ignores email compliance?
Beyond risking fines, ignoring CAN-SPAM or GDPR erodes trust. Always provide clear opt-outs, honor unsubscribes, and avoid misleading subject lines.
Trust is one of the most valuable assets your brand has, and email is an opportunity for winning that trust—or losing it.
Why This Matters for Business Leaders
For CEOs, owners, and VPs, email isn’t about the mechanics of HTML templates. And it’s not about blasting out an email everyday (or multiple times a day!) to everyone in your database. It’s about results. When done right, email campaigns deliver consistent leads, higher retention, and measurable sales impact.
One reason small to mid-sized businesses partner with our Denver-based agency Stratos Marketing Group is to ensure their email campaigns don’t just look good but actively contribute to revenue growth. And if you’re ready to take your campaigns further, Stratos Marketing Group can help you build and execute a strategy that gets real results.
