Sometimes, a perfect email isn’t enough. Despite spending hours polishing the subject line, refining the visuals, and crafting that all-important call to action, the results still fall flat. The open rates dip, the clicks stall, and the conversions don’t show up.
In these moments, it can seem as though your audience has stopped caring. But that’s likely not the case – instead, it’s often an indication that your email marketing needs a refresh.
So, if your email campaigns aren’t performing as expected, here’s what to look at, what to tweak, and how to get your results back on track.
Take a look at the bigger picture
Before you hit “delete” on your whole strategy, take a step back. It’s easy to focus on one underperforming email and zoom in on the details, but looking at the bigger picture can also tell you so much.
Start by looking at the trends, not the numbers in isolation. Are open rates gradually slipping, or was this a one-off? Are some audiences engaging more than others? The data often tells a bigger story – and it can point you directly to where your attention is needed.
If performance has dipped over time, it’s a sign to shake things up, but if it’s just a single outlier, it could simply be timing, topic, or inbox fatigue.
Put time into your subject line
Your subject line is your first chance to grab attention. With inboxes more crowded than ever, people make split-second decisions on what to open and what to delete.
If your open rates are low, your subject line might not be doing its job.
So, why not try this:
- Keep it conversational. People are drawn to language that feels human, not robotic.
- Spark curiosity. Think of it as a news headline, it should make people want to know more.
- Personalise when you can. Using first names or referencing behaviour (“You left something in your cart!”) can make a big difference – beware though, your data needs to be super-accurate if you are going to do this.
- Test, test, and test again. A/B testing subject lines is one of the easiest ways to find what resonates, and what truly works – try using emojis, asking questions, or shifting tone.
Keep it human
If people are opening but not clicking, your content might just be missing the mark. It could be too long, too formal, or just not giving your readers what they want. Today’s audiences want quick, valuable, and human content.
So, ask yourself:
- Does my email sound like a person, or a faceless brand?
- Is there a clear reason for the reader to care?
- Am I providing something genuinely useful – is it inspirational, insightful, or a next step?
Think of every email as a mini conversation. The tone should sound like your brand, but also feel like it’s written by a real person. Use contractions, keep sentences short, and make your calls-to-action crystal clear.
Don’t be scared of segmentation
One of the most common reasons email campaigns underperform? Sending the same message to everyone.
Your audience isn’t one big group; it’s made up of different people at different stages with different needs. So, when you send every email to everyone, it’s harder to make it relevant (and easier for people to tune out).
Segmentation helps you speak directly to smaller groups in ways that resonate. For example:
- Loyal customers might love behind-the-scenes updates.
- New subscribers might need more education or trust-building.
- Inactive users might respond to a “we miss you” or special incentive.
Personalised content feels like a conversation while mass content feels like noise.
Check in with your tech
Sometimes, underperforming emails have nothing to do with content, it’s the tech behind the delivery that’s the problem.
A few key things to check:
- Your sender name – check if it’s clear and recognisable.
- Mobile optimisation – more than half of all emails are opened on phones, so if your layout isn’t mobile-friendly, you’ll lose readers, fast.
- Deliverability – if your emails are landing in spam or promotions folders, your audience may never see them at all. Tools like Transpond, Mailchimp or Mailerlite help monitor deliverability health.
- Links and CTAs – make sure all your buttons work, go to the right place, and are visually easy to find. No one wants to be left searching for your reference.
The reality is, if the tech’s off, even the best content can flop.
Rethink the ‘when’
Another factor that often gets overlooked is when and how often you send emails.
Sending too frequently can lead to fatigue (and a surge of unsubscribes), but sending too sporadically can make your audience forget who you are. The sweet spot depends on your industry and audience, but testing is your best friend here.
And remember: consistency builds recognition. You want your audience to see you as a familiar name, not an intrusive one.
When it comes to the when, the best time depends on your audience. A B2B email is best landing in inboxes on a Tuesday, Wednesday or Thursday morning, whereas a B2C email might be best evenings or weekends. Choose a day and time that suits your audience to achieve the best results.
Ask yourself: What are you trying to achieve?
Deciding on a goal for each campaign is a good way of setting and tracking expectations. To do this, first ask yourself what ‘success’ looks like – sometimes we set expectations that don’t match the intent of the email. A newsletter might be designed to build brand awareness, while a product launch aims to drive sales. Measuring both by the same yardstick doesn’t make sense.
Be clear about what you want each email to achieve. Then, you can track the right metrics – open rate for awareness, click-through for engagement, or conversions for direct sales.
That clarity will also help you create more purposeful content next time.
