9 Creative Marketing Ideas for May Emails

Now when you know when to write, let’s see what email content creation ideas you can adapt.

1. Experiment with fonts.

You don’t need many images or a complex layout to make your campaign look nice. Smart usage of fonts, colors and white space can do the job as well.

By the way, in the eSputnik system, you can add any font you want in several clicks. They will get available in the editor right after you click final Save.

2. Add animation.

Animated elements never leave the list of email design trends. They make any campaign look more festive and dynamic. Plus, animation is a life-saving marketing idea for small businesses that don’t have budget or technical possibilities to run a special photoshoot.

3. Promote related products.

Think what products of yours may resonate with a particular holiday and come up with the corresponding launch. As an example: last year, GiftBasket launched a special pizza kit for National Pizza Party Day.

4. Add a countdown timer.

A good old countdown timer puts a focus on a time limit and prompts faster decision making. How to add one in your ecommerce email is clearly explained here.

5. Use a simple promo code.

Whatever occasion it’s dedicated to, make a promo code easy to use. A short memorable word like the below GOTH20 is better than say GthyFGthkjijip890mi.

6. Run Best of May.

Or any other campaign focused on the best products of the month, Staff Choice, What You Liked This Month, Best Sellers of May, etc.

eCommerce email with sales

In eSputnik, you can create personalized product recommendations featuring bestsellers or popular products. Select the necessary recommendations algorithm, upload your site data source and assign it to the email template with recommendations. The system will automatically be adding items to emails based on their sute category and availability.

7. Employ gamification.

A great content idea in itself, gamification is a useful tool to keep your subscribers entertained. It also increases the average read time and depth, prolonging the interaction with your brand.

Email with gamification

8. Run a challenge.

And speaking of entertainment, challenges are also a great way to engage your audience. Think what activity resonates with your company and offer small incentives for participation.

Email with the challenge

9. Add a video.

Use a how-to tutorial to explain how to use your product and give people more reasons to buy it.

Whatever campaign you send, make sure you segment your audience properly and optimize sending time. The right offer sent at the right time is what makes the most high-performing campaign.
