To Enhance Email Open Rates, Use Effective Subject Lines

Why pay attention to subject lines?

A great email begins with a subject line that captures your recipients' attention. People are more likely to read our content if the subject line is personal or descriptive. Whatever strategy we use, it's important to keep your audience in mind and try out different words and phrases to see which ones they like.

Strategies to enhance open rates on email subject lines:

Should be descriptive- Instead of seasonal slogans, convey the benefits of your promotions or draw attention to specific discounts in the subject lines.
When compared to big subject lines (8+ words), short subject lines (less than 7 words) perform 65 percent better. Long email subject lines are sometimes misinterpreted as an indication of poor email content. Less is more in this case.
Keep punctuation to a minimum—no more than three punctuation marks per subject line is ideal. If you use too many punctuation marks in your email, it will appear spam.
Make use of numbers-numbers have a way of impressing people. They can also help you get some reputation. Why not put it in the subject line if you have precise data to provide (or should have).
A/B testing- A/B testing or split testing your email subject line is producing and comparing two or more variants of your subject line and separating the one that performs better or stimulates the attention of your audience.
