Email is an essential user acquisition channel that surpasses top social networks, like Facebook and Twitter, in terms of effectiveness. 

Although ad tech has notably evolved, moving from the 90s era of banners to IoT and virtual & augmented reality following 2019, over the last 6 years, email marketing performance metrics have remained almost constant. For example, the average open rate in 2016 for the TOFU channel was 44.22%, while as of 2021, it’s 42.45%. 

Buyers do pay attention to emails. And even though people don’t always proceed with purchases upon offers they receive, emails help maintain customer relationships and build brand awareness.

Crafting Attention-Grabbing Newsletter Subject Lines

Writing a great newsletter subject line can be a daunting task. Your subject line is the first thing your readers will see, and it can make or break whether they open and read your newsletter or simply delete it. But don’t worry, we’ve got you covered!

By following these tips, you can craft newsletter subject lines that grab your readers’ attention and encourage them to engage with your content. So go ahead and give it a try – your readers will thank you for it!

What to keep in mind while creating a subject line for the newsletter:

  • Consider including the month or date to give your message context.
  • Clearly communicate any deadlines or time limits.
  • Highlight the main topic of your newsletter to grab readers’ attention.
  • Be concise and focused in your message.
  • Make sure to mention your organization’s name.
  • Encourage reader participation by asking a thought-provoking question.
  • Use strong action verbs to create a sense of urgency and encourage engagement.

Best Examples to Create a Newsletter Subject Line

How will the first newsletter subject line influence the email open rate? The answer is — it depends on the primary purpose of the campaign you launch, the words you choose, and the general intonation that you express. 

For example, if there’s a bit of urgency in opening lines, your emails may get up to a 22% higher open rate. At the same time, too promising or pressing phrases can cause email newsletters to seem fraudulent, and it won’t pass through the anti-spam firewalls of mailing systems.

The type of mailing determines the style of its subject line, as well. While a weekly newsletter gives a wide space for experiments, there are common rules when writing follow-ups, confirmation emails, offers, or invoices, right?

The headline will hinge on the lead gen funnel stage too.

Monthly Newsletter Subject Lines

For regular mailings, you should start with determining the appropriate frequency. Too rare or incessant emails may adversely affect your open and click-through rates. In the first case, people will forget your brand, and in the second case, they will be annoyed and willing to unsubscribe. 

A commonly recognized and rather safe happy medium is 2-4 newsletters per month.

With an eye out for low regularity, subject lines for monthly newsletters should promise some value, for example:

  • reveal important updates or news
  • disclose advice from experts on changes in legislation or industry 
  • show a personalized collection of new products or services, etc.

A recipient needs to get an all-embracing and comprehensive piece of interesting information. This doesn’t necessarily have to contain a commercial intent. Consider these subject line phrases:

Holiday Newsletter Subject Lines

A festival, an independence day, a religious holiday — these are good reasons to remind recipients about your brand casually. The newsletter may be designed upon a newsbreak, say a Christmas sale, or it may simply contain a beautiful greeting card.

Thanksgiving newsletter subject lines

  1. So many people to be thankful to / Time to give thanks to your beloved ones!
  2. Give thanks to your dearest ones — {discount amount} on everything!
  3. It’s X weeks away from Thanksgiving! Have you already prepared gifts?

Halloween newsletter subject lines

  1. Happy Halloween! We treat wizards and witches with a 31% discount
  2. A “Trick and Treat” day is coming! Stock up on sweets in our store 
  3. A Terrific Halloween Offer! One-time $31 off on chart over {money sum}.

New Year newsletter

  1. {New Year’s/ End of the Year/Year End} Sale
  2. New Year is coming in 3 weeks! End-of-year clearance at {the website}
  3. New Year with bigger & better deals at {the website}

Christmas newsletter

  1. You will like these 20+ Christmas {decorations/designs/presents/cards}
  2. {Recipient’s name}, don’t forget to pick a present for yourself
  3. All HE wants for Christmas is… 10 gift ideas under {the sum}.

Valentine’s day newsletter

  1. Perfect Valentine — Gifts with a 14% discount
  2. We love you! 20% Off this week
  3. Happy Valentine’s Day! A present from {your company} is here for you.

Internal Newsletter Subject Lines

Although internal open rates are high (around 68%), that’s not an excuse to send an email with  an empty subject line or a boring “FYI.” If the company’s corporate culture is fairly democratic, you can use comic headlines or add funny emojis. If not, just be laconic yet specific:

  1. Yesterday we won the tender. The next steps
  2. Morning stand-up’s summary
  3. At 3 pm we discuss {the project}. Skim through agenda beforehand (attached)
  4. [URGENT] Your action required: {the matter}
  5. January update on sales — key numbers.

Newsletter Subject Line Best Practices

We would like to sum up this post with a universal formula of a great email subject line, but, unfortunately, it doesn’t exist. The only way to write it is to understand the audience and follow some common recommendations:

  • keep it short: up to 60 characters
  • don’t get too carried away with emojis or all caps
  • avoid spam words
  • personalize, where relevant
  • include numbers
  • use vertical separators (“|”) and capital letters to emphasize key messages.

For cold emails and bulk drip email campaigns, some good subject line generator services may do just fine. It’s better to write subject lines yourself and make them more human-like.


“You can generate cold email subject lines by mentioning keywords and a few more specifications using Reply.io”

Mailing is a powerful marketing tool, but only if emails are designed correctly. You can only see what’s working if you try it out. So before scaling up, take time to conduct an A/B test — to be sure the hypotheses that you put forward will work out as planned.
