5 Best practices to craft the perfect email subject line

With so many people sending emails and asking for resources, catching your recipient’s eye can be difficult. However, this doesn’t mean that you should give up. Instead, following some best practices when writing your email subject lines is essential.

Get personal

Use the recipient’s name in your subject line. This trick has been used repeatedly by marketers who want their emails to stand out, and it works! Personalized subject lines can increase the open rate of your emails by 50%.

Adding their first name can make recipients feel more connected with you, making them more likely to open the message when they see it in their inboxes.

Don’t have their names? Some email finder solutions, such as Clearbit Connect, provide the relevant contact at the company you want to contact after entering its name. You can look at the best email finder tools discussed in our blog.

Another way to add a personal touch to your subject lines is to think of original ways to include their company name or location in your subject line.

Now that you know the power of personalization, use this technique whenever you can.

Neither too long nor too short

A subject line that’s too long or short can decrease your open rates. Keep it between 36 and 50 characters. This length will ensure that your email gets read. Longer subject lines will be cut off, and the recipient might skip over or delete your message immediately. On the other hand, short subject lines can prevent you from clearly stating your goal and make you sound vague. Remember that you need to be specific in what you ask for to help the reader quickly figure out why you’re reaching out to them.

Take advantage of helpful tools when doing guest posting outreach

Sending guest post pitches can be a time-consuming and tedious process. Consider using tools that can clear your way.


BuzzStream helps you build and segment your contact lists to organize and set your guest post outreach email campaigns easily. It features customizable templates to send the same emails to different recipients. BuzzStream also allows you to track response rates and gives you valuable insights so that you can tailor your pitch accordingly. The app also suggested some possible contact details of people working in the company you will reach.


If you send out many emails, it’s easy to make a typo or two, even when careful. This can make you sound unprofessional and reduce the effectiveness of your outreach. Grammarly is an advanced proofreading and grammar-checking tool that can help you avoid grammar mistakes in your subject lines and email messages. It will check for errors and problems with sentence structure and punctuation, such as unnecessary commas or quotation marks.

Avoid being marked as SPAM

Did you know that the average percentage of emails caught up by spam filters is 15.8 for all email tools? So, avoid using spam-triggering words in your subject lines. People are sensitive to such words, as they rarely deliver on their promises.

Also, email providers have their spam complaint rate limit. If you cross it, they might suspend your email. HubSpot’s spam report limit, for example, is 0.1%.

Test and improve

A/B testing is a method of experimentation to determine the effect of changes on some metric. The best way to figure out which subject line works is to test them. For example, send two different versions of the same email subject line to two different groups of people. Then, compare their open rates, see which one performed better, and use it for your next guest post outreach.

Time to get your guest post pitches accepted

These subject line tips and ideas will surely bring some inspiration for your next guest post outreach campaign.

Also, put yourself in your recipient’s shoes and think of the subject lines that would make you open and read the emails. Which emails in your inbox have you clicked on?
