Why Summer Months Are Smart Time for Email Marketing
People may be harder to reach during the summer, but that doesn’t mean they aren’t checking their inbox. In fact, email becomes even more valuable when attention spans are shorter and social feeds are flooded with vacation content.
Your subscribers are still shopping during the summer months. They’re just doing it from their phones at the lake or after dinner on the patio. With the right subject line and timing, your email can be the one they open and the one that gets the click.
Summer email newsletters help you engage your audience by:
- Promote seasonal sales and new product launches
- Strengthen customer loyalty with lighter, feel-good messaging
- Build engagement through helpful tips, giveaways, or how-to content
- Keep your brand top of mind during a slower season for many industries
Email newsletter templates give you a running start with content ideas. Instead of designing each campaign from the ground up, you can drop your content into a structure that’s already built for conversions.
Now, let’s look at the best summer newsletter ideas and how to use them effectively.
Mobile Optimization for Summer Months
During the summer season, 75% of people read email newsletters on mobile while enjoying outdoor activities. This is the perfect time to optimize your campaigns:
- Bright, contrasting colors for outdoor reading in sunlight
- Larger CTA buttons (minimum 44px) for easy tapping during summer activities
- Short subject lines (under 30 characters) for mobile preview
- Single-column layouts that capture the summer vibe
These summer-themed optimizations help engage your audience regardless of where they’re reading – at the beach, by the pool, or during travel.
