The open rate is basically the variable you need to measure to know if your subject line is working or not. But there are a few things you can do to try to increase the open rate, such as:
Invest a lot on your lead generation process. This is a key factor to increase your open rate. You have to make sure you are reaching out to the right decision makers about your product if you want them to open your email. Your efforts will go to waste if you are knocking on the wrong door.
Find the perfect time to send emails. Depending on your business and on the business you are trying to sell to, you need to find a good time to send your emails. I normally approach B2B companies and so far we have been achieving good results by sending emails early in the morning. Each case is different, and what works for me might not work for you, so you always need to A/B test in order to define the best timing and process for you.
Use a catchy subject line. If you want people to open to your emails, you have to catch their attention in the subject line. Create a sentence about your offer that might lift the veil for the prospects, or use their name and company name to make them curious enough to open your email.
Keep the body of your email short and clear. People don’t have a lot of time to read emails, and they use their time very wisely prioritizing the emails they think are more important. So keep your email short and clear, focus on benefits instead of enumerating features and don’t forget to include a clear call to action to make the prospect understand you are waiting for them to take action.
Personalize your message as much as possible. Every prospect likes to feel special, so put some thought and time into your emails before sending them. Refer to something their company achieved recently, or share a case study you think might pick their curiosity.
