Tips to great newsletter subject lines that get opened

According to CoSchedule, 35% of email recipients decide whether to open an email or not judging by the email subject line alone, while 69% of recipients report email as spam and throw it in a spam folder, driven by the same reason.

We have thoroughly researched the web and asked our email service provider to conduct a short survey to provide you with the following tips for writing impactful email subject lines:

  • watch the length of your email subject lines. Gmail desktop shows 70 characters of your email subject lines, while Android Portrait on mobile devices shows only 35;

  • use numbers in your email subject lines. They grab recipient's attention — preferably, write them in numerals, not letters;

  • personal subject line makes customers feel special and valued, so use them to your advantage;

  • avoid spam words and punctuation like multiple exclamation points at all cost if you don't want your emails end up in spam filters;

  • add descriptive preheader text;

  • be direct and concise when creating your subject line(unless it is a teaser email);

  • use intriguing email subject lines;

  • stand out — don’t be afraid to be funny in your subject line when it’s reasonable;

  • if you are an e-commerce website, urge your customers and notify them in your subject line of how many days the sale will last;

  • don't hesitate to tweak your email subject line to match your brand voice;

  • include emojis to spice up your email subject line;

  • use conversational words to invoke the fear of missing out a great deal;

  • even though you don't want to be overly promotional, you shouldn't be afraid to be direct either;

  • look at your own inbox to see how others create their subject lines. Write down the hits to try in your next subject line.

How to add a subject line and preheader to your emails with Stripo

To add a subject and preheader to your emails, you need to:

  • click the Settings button above the template;

  • enter your email subject line in a respective field;

  • enter preheader text if you like. If you do not feel like writing and adding any preheader text, just activate the Fill in with white space option. Otherwise, recipients will see the first elements of your email as the preheader text.

Setting Subject Lines with Stripo

For your convenience, Stripo counts the number of characters you enter in both fields. 

Thank you for your time and for reading this blog post. I hope that the tips and these great examples given here will help you write email subject lines that will amaze your audience and bring you sky-high open rates.
