Austin Rose, Email Marketing Strategist for Radar Strategy Group, shares tips for improving your email campaigns' open rates through subject line optimization. 

Did you know that the average consumer spends about two seconds deciding whether or not to open an email? So it's crucial to have a subject line that stands out in their inbox. 

Here’s a few tips to improve your email subject lines:

1. Keep it short. The best practice for length is 15-40 characters.

2. Use numbers. Have 2 new products or 3 recent blogs you're sharing? Include the digit in your subject line.

3. Tease. Your subject line should hint at what's inside the email and intrigue your customers enough to open it. 

4. Add an emoji. Most people open emails on their phones, and emojis stand out on mobile. Even if your brand voice isn't light-hearted, you might be able to find an emoji that works - like a stethoscope if you're a doctor's office. 

5. Test! And test again! Try splitting your list in half and sending two subject lines with only one difference and see which does better. Then, you can use this winning tactic in your future campaigns.
