8 Creative April Email Marketing Ideas

Now let’s take a look at how you can spruce up email content this April. The advice here would be simple to follow – use bright colors, add spring-related elements, and put seasonal items on display.

1. Choose the right template.

You need a good canvas to squeeze all your ideas in. Choose the template that will be easy to adjust to your tasks and edit without code.

In our drag-and-drop editor, we offer 480+ free HTML templates that you can filter by keywords (Easter, Fool's Day, etc.). The editor is a block builder that allows to build templates of ready blocks and add or delete any element(text, CTA, image, video) in several clicks.

2. Promote seasonal essentials.

Camping, gardening, trekking, BBQ – there is a number of activities associated with spring. If you produce any products or services applicable for such activities, put them upfront or run a separate campaign with a focus on them only.

3. Add floral imagery.

Nothing sets the spring mood better than an elegant bouquet of flowers. If your service hardly resonates with any floristic patterns, consider using at least one element (petal, blooming branch, leaf, etc.) to give your campaigns a bit of springtime vibes.

4. Give useful tips.

Gardening advice, styling sessions, spring skin care routine, sun protection, renewal design – explain the subscribers how to use your product this month with maximum effect.

5. Solve the problem.

Wind, rain, and mud are among the main threats to outside activities in spring. Outline those advantages of your product that help handle the situation – for example, keep feet dry or hairstyle wind-proof.

6. Set the time limit.

To speed up the decision-making process, create a countdown timer or offer a limited edition collection. Most often, the fear of missing out prompts people to set their minds faster.

7. Launch April showers.

“April showers bring May flowers” refers to email marketing as well. April showers is a term used as a referral to winter clothing and clearance, hot spring deals, and springtime sales. Offering good April discounts? Make sure your audience knows about it.

8. Show what’s trending.

Call it whatever you want – April bulletin, A-list, Best of April, April top deals, etc. The main ideas of such campaigns are to underline your brand’s current trends and top offers.

---

Seasonal emails are a great opportunity to get in touch with the subscribers and welcome the new month with bright and catchy campaigns. A smart subject line, custom images, and lucrative deals would let the brand's personality shine with new colors provided you start planning ahead straight away. And be sure, April showers will bring result flowers.
