Pro Email Marketing Tips

Here are some pro email marketing tips to make sure you nail it when choosing a smart email subject line.

1. Don’t add RE: to subject lines unless you are responding to somebody.

2. Don’t use all caps. In most cases, I recommend using a sentence structure form of writing.

3. Make sure you haze ZERO spelling mistakes. Keep in mind that we are aiming at a grammar perfect subject line.

4. Don’t use one-word subject lines. We want to keep it inviting and calling, one-word subject lines are not ideal for this.

5. Don’t use exclamation marks at all! Many people still make this mistake.

6. Keep it precise and straight to the point.

7. Try using an emoji. Statistics show that subject lines with an emoji, get close to 50% open-rate.

8. Never forget that most people open their emails via mobile, so no matter the occasion or urgency, always make sure your subject line is optimized for mobile phone viewing.

9. Always keep it original. You don’t want your first-time email subscriber getting bored or having that “this is one of those emails I am always ignoring” kind of feeling.


With this in mind and well-executed, your next email campaign will be nothing but spectacular. However, don’t forget that subject lines are just a tip in the iceberg. There is more to that for an effective email marketing campaign. For instance, how do you structure your content? Have you had a look into your email deliverability configurations? Are you using the right mailing platform? Which email marketing metrics are you focusing on? What’s your budget?

Email marketing is a prerequisite if at all you are determined to improve on your sales and to a larger extent get a positive ROI. Avoid Email Spam Trigger words at all costs and make sure to bookmark this blog and we will tell you exactly how to achieve this.
