10 Ways to Improve Your Email Marketing and Boost Engagement
Here are common email marketing mistakes, and how Adcetera can fix them to help drive better opens, clicks, and ROI.
Email marketing remains one of the most cost-effective channels for engaging customers, driving conversions, and nurturing long-term relationships. In fact, email delivers an average ROI of $36 for every $1 spent, a clear sign it is still one of the most powerful tools in your marketing mix.
But success isn’t guaranteed. Deliverability challenges, disengaged audiences, and poor execution can doom a campaign before it even begins. So, what’s keeping eyes off your emails?
These are 10 common mistakes that cause email campaigns to struggle to build brand awareness, engagement, and customer relationships, and how Adcetera, a leading digital marketing agency, helps you overcome them.
1. Generic, Vague, Long, And/Or Spammy Subject Lines
The subject line is your first impression and often your only chance. If it’s vague, too long, or triggers spam filters (“Free!!!” “Act now!!!”), your message won’t stand a chance.
How We Can Help: Our content and creative teams craft subject lines rooted in research, not guesswork. We combine audience insights, tone alignment, and A/B testing to strike the right balance of intrigue, clarity, and deliverability so your emails are opened for the right reasons.
2. Over Reliance on Copy Alone
A fascinating story isn’t enough. Audiences prefer to read words that are surrounded by fun colors, unique shapes and layouts, relatable photography, attention-grabbing motion, and interesting interactivity.
How We Can Help: Our creative team builds branded email templates that combine storytelling with design, including clear hierarchies, mobile optimization, motion, and interactivity. That way, your emails don’t just get read, they get remembered.
3. Ignoring the Data
Relying on gut instinct isn’t a strategy. Open-rate insights, click-through patterns, and content relevance help identify what works. Behavior-based targeting, lifecycle marketing, and demographic distribution can add predictability to campaign performance.
How We Can Help: We implement tracking, dashboards, and A/B testing so you know exactly what’s working. Our data-driven approach ensures every campaign is smarter than the last.
4. SYOE (Sending Your Own Emails)
Sending one-off emails from a personal inbox doesn’t scale. Email marketing automation platforms can integrate with CRM, social media, scheduling, and other marketing tools. Some platforms are sized for small-to-medium businesses; others are optimized for ecommerce. There is one built with the right feature set, pricing, and use cases for you.
How We Can Help: We help identify and implement the right email platform for your business. Whether it’s Salesforce, HubSpot, or another solution, we integrate CRM and ecommerce data to automate campaigns while keeping the experience human.
5. Sending Without Strategy
Don’t just reach out because it’s been a while. Email campaigns need segmentation, follow-ups, and flow. Users who clicked the first email get a different journey than those who didn’t. Plan touchpoints that build toward a final event with opportunities for feedback.
How We Can Help: We design strategic customer journeys. Every touchpoint, from welcome series to re-engagement campaigns, is mapped to recipient behavior and business goals, ensuring every email has a purpose.
6. Doing The Same Thing Over and Over
Without testing, you never uncover what resonates. Evidence-based decision-making reveals what actually works, improves metrics, and allows for small revisions that can have measurable effects. It also gives you a chance to try something outside your comfort zone with a sample audience and find a clear winner before committing to a full rollout.
How We Can Help: We structure experiments that compare subject lines, CTA placement, visuals, and send times. Then we scale winning ideas across campaigns to continually increase performance.
7. Treating All Audiences the Same
A “one-size-fits-all” email feels impersonal and irrelevant. Personalization makes emails more relevant, more interesting, and more intimate. That boosts engagement, trust, and conversions. It shows you’re putting in the effort to get to know what each member of your audience cares about, and they take notice.
How We Can Help: We segment your audience using behavioral data, demographics, and engagement levels. Then we personalize creative and content so every subscriber feels the message was written just for them.
8. Crossing Inbox Boundaries
Think beyond opt-in and spam. Set expectations, give recipients some control over their frequency preferences, and deliver at the cadence you promised. Ensure your segmentation is appropriate and you apply behavioral data responsibly without being overly invasive.
How We Can Help: We build frameworks for send frequency, set up preference centers, and apply compliance protocols that respect your audience while maintaining engagement.
9. Winging It
As easy as email campaigns seem, they also have their own set of best practices for effective performance. This starts with building and maintaining a healthy recipient list and incorporates everything from regulatory compliance to omnichannel integration.
How We Can Help: We maintain healthy lists, remove inactive subscribers, and ensure compliance with CAN-SPAM, GDPR, and other regulations. That way, your campaigns land in inboxes, not spam folders.
10. Trying to Do It Alone
Email marketing looks easy from the outside, but effective campaigns require strategy, design, data, and compliance expertise working together.
How We Can Help: We act as an extension of your team. From message crafting to design, automation setup, campaign rollouts, and full-service management, we’ve guided startups, Fortune 100s, and everything in between to email success.
