If you are already sending newsletters, promotional or automated emails, you have the basics covered. The database exists, the tool works, the campaigns go out. But often the results are not optimal. Small changes in the way you approach emails can make a big difference – higher open rates, more clicks, and increased sales.
Why generic emails often don't work
Many marketers still use generic subject lines, such as “New collection” or “Special offer”. The problem is that the recipient doesn't see why they should open the email. Subject lines that immediately show a specific benefit or limited opportunity work better.
For example, instead of “Sale this weekend” you could write:
“Your discount expires today at midnight” or “Only 17 items left at this price”.
You can achieve an even stronger effect with a subject line that includes the recipient's name or email address, especially when reactivating an old database: “jan@example.com – are you still using this email?”
One clear action per email
Too often an email looks like a mini website – multiple banners, multiple CTAs, too much information. As a result, the user decides on nothing.
An email should have one main goal, one clear CTA, and everything else should be secondary or removed. If it's a promotional email, only one product or one category should be highlighted. A reminder email should lead back to the cart, while an educational email can include one blog post or guide.
Value, not just sales
If every email calls for a purchase, the database quickly gets used to it and responsiveness decreases. It helps to occasionally send useful tips, product use cases, or answers to frequently asked questions.
Examples that work:
- “How to choose the right product for X”
- “The most common mistake when using this product”
- “Why customers return this product and how to avoid it”
Such emails increase engagement and make subsequent sales emails more effective.
Additional concrete email marketing tricks that really work
If you are already regularly sending email campaigns, there are upgrades to classic tactics that bring better results without major discounts. The key is to test them with A/B testing, as not everything will work for all segments of your database.
Showing limited stock or personal limits is a surprisingly powerful trick. Instead of a generic “Sale this weekend”, you can include in the email: “Only 3 items left — get them now!” or “Only 7 people viewed this product in the last hour”. Such information triggers a sense of urgency and often increases immediate clicks and sales, especially for users who have already shown interest.
A similarly strong effect is achieved with a countdown timer in the email. When the recipient sees time ticking away, they respond faster than with a regular date in the subject line. The countdown should be at the top of the email, with visible colors and a clear CTA, for example, “Take advantage of the offer until …”.
To re-engage an old database, you can also try personalized subject lines with the email address. Example: “jan@example.com – are you still using this email?” Such an email often achieves a high open rate, but use it thoughtfully, as too many can trigger a spam feeling.
If you want to reduce psychological barriers to purchase, an effective trick is to offer risk-free options. These can be free shipping, a 100% refund, or a 30-day risk-free trial. This principle often increases the average order value, as users decide to buy knowing they risk nothing.
Including social proof is also extremely effective. You can add customer reviews, testimonials, or short screenshots of comments in the email. For example: “⭐ 4.9/5 – 324 reviews” or “See how others have used this product”. People don't just buy because of a discount, but because of proven value and trust.
Consider multi-part sequences for abandoned carts. Instead of sending one email, send three: first a gentle reminder, then add social proof, and finally use an urgency element, for example: “Offer expires in X hours”. This approach often yields better results than a single reminder.
For those with many inactive recipients, an effective re-engagement or “win-back” email is not directly sales-oriented but tries to re-establish contact. Examples: “We miss you — here’s something you might find interesting”, “See what has changed since your last visit” or “Choose what you're still interested in — help us send you better content”.
A/B testing – the only way to know what really works
Even the most well-thought-out emails are not always optimal. A/B testing is crucial because every database reacts differently. Test one element at a time – subject line, CTA, content, or sending time – and measure what brings the best results.
Example: two versions of an email, one with the subject “Your discount expires today at midnight”, the other with “Sale this weekend”. The result shows which version achieves a higher open rate and conversions, allowing you to optimize future campaigns.
Measuring the real impact
Don't just look at the open rate. It's important to know which email actually brings in the most revenue, which type of email generates the most conversions, and where users stop or click. Often it turns out that an email with a lower open rate still increases sales or average order value.
If you are already sending emails, you don't need a revolution. Most often, small, thoughtful changes help: clearer subjects, one clear CTA, content that resolves doubts and builds trust, the use of advanced tricks (FOMO, countdowns, social proof), reactivation emails, and A/B testing to precisely see what really suits your audience.
You can implement these changes immediately, without new tools or databases, and maximize what you already have.
