Writing email subject lines is maybe as daunting as trying to find the key to a door that holds the elixir of life out of a thousand similar options - or maybe that is a little bit of an exaggeration.

However, a good email subject line is equal to the elixir of life, the elixir of your email marketing life.

Your subject lines affect your open rates and pique your reader's curiosity. You will never be able to get your email subscribers to read your emails unless you write great email subject lines.

You can scan your own inbox and spam folder to see which subject lines are intriguing, which ones landed in spam, and which ones are compelling you to open the email.

Make sure you differentiate between newsletter subject lines and those meant for drip campaigns. Those for newsletters are more like announcements while drip campaign subjects are more creative.

Let's check out how you can craft a great email subject line and some fantastic examples for inspiration!

Do this in the Subject Line

  1. Keep your subject lines short so that they do not get cut off on mobile devices. A maximum of 5 to 6 words is ideal.

  2. Catchy subjects are not necessarily better than straightforward email subject lines.

  3. Highlight customer pain points.

  4. Use conversational words to make it seem like a human is talking to a human - add a personal touch.

Don't do this in the Subject Line

  1. Do not include spammy words such as Free, Buy Now, etc. It will affect your email deliverability.

  2. Avoid using hyperbole or multiple exclamation points!!! Using them will prevent you from getting through the spam filters.

  3. Try not to be overly promotional - create a sense of excitement and urgency without sounding like you are exaggerating.

These are the basic rules of writing subject lines. However, you need to aim for fantastic.

So, now let's dive into the specifics of how you can do an excellent job with your email subject lines.

Use numbers

Numbers are really effective in conveying a message and grasping your reader's attention. Whether you have an exclusive offer or want to convey that the price dropped off an item, convey that in your subject line with numbers.

For example, $10 today and $1000 next week is an example of a subject line that makes a strong first impression and is likely to have a high open rate.

Other numerical subject line examples include:

  • A 70% increase in sales in 14 days

  • Lose 50 lbs in a month guaranteed

  • A vacation in only $150 per month

Begin with verbs

It's a good idea to give a call-to-action in the email subject line or give a direct command. For example, your subject line can be "Join Us at the Tech Conference" or "Pay Later, Do Now".

Beginning your subject line with a verb can help your email recipient decipher exactly what the mail is about and whether they would be interested in what you are asking them to do.

Tease the reader

Tease the reader like you tease your crush!

Give them a sneak peek into what the email is about without revealing everything. You can pose this as a question, as a comment, or as a quote that lets email recipients wonder what the rest of the email may be about.

Some great email subject line examples for teasers include "Stop wasting money" or "He deserves to live" for a human rights campaign.

When talking about an exclusive deal for lipstick on an e-commerce website, you can say something like, "It's raining colors this week".

Marketing campaigns with teasers often get a lot of attention and some of the best email subject lines are teasers!

Make an announcement

You can go for a simple subject line if you have an announcement. Include your company name and tell your readers exactly what is happening. For example, "Pribox is attending SaaSter" or "The Family Gala 3.0 winners are...., "are simple but good email subject lines.

You can also write the title of a blog post in your subject line if your email contains a link to that particular piece of content.

Be funny

If your brand voice is funny, young, and easygoing, it is perfectly fine to inject some humor into your subject line. You can tell a joke or make a comment that is likely to make your recipients smile.

Humor often results in more engagement and if it is injected into a subject line, it can result in a higher open rate. Mailerlite suggests trying it out but not going overboard with humor and also making sure you are addressing the customer's pain point while being funny.

Give deadlines

Personal subject lines do not need deadlines - unless you are waiting for an answer to a proposal.

However, if you are writing to a business or a customer and want them to act within a certain period, you can include a deadline in your subject line. A subject line example would be, "You have three days to join us!" or " Registration ends in 24 hours".

This subject line makes the reader act quickly if he/she is interested. Giving deadlines can significantly increase your open rates as your recipients get a now or never aura from them.

Personalize

You can add tags to include your recipient's first name in the subject line to give it some personalization. However, there is no need to over-personalize. That means that all of your campaign's emails should not begin with the recipient's name.

For example, the first email in your campaign can be, "Laura, earn double points today" and the next one can be, "Great job, you are not far from your goal". Notice that both subject lines do not include the recipient's name.

This is not a personal email so you need to maintain a certain decorum in a sales email. Your goal is not only to keep the reader engaged in your words but to nudge them through the sales process.

Provide a solution

What is the difference between good subject lines and great subject lines? The best subject lines engage the reader and provide a solution to a problem they have. As mentioned earlier, you need to address the recipient's pain points and offer a solution.

One subject line example that does this is, "Strength solution means no more broken and chipped nails", telling the recipient that if they want to solve this problem, the solution is only a click away.

Ask questions

Asking questions in a subject line is a great way to get readers curious or to address one of their pain points. For example, if you are trying to grasp the attention of someone who is trying to upskill for a promotion, you can ask, "Does that promotion seem unattainable? " or if you are emailing a bride-to-be you can say, "Do you have the Big Day jitters?"

The appropriate questions resonate with people and would get them to open the email and see what you have to offer.

Bottom line

Make sure that you try different subject lines and the A/B test to see what is working. You might want to segment your list and keep new subscribers separate from old subscribers to see how they respond to your brand voice and tweak it accordingly.

Ensure your brand voice is consistent with your brand image and don't try anything too surprising unless you are sure your target market will resonate with it.

Warm up your email domain

Also, ensure that your email domain is warmed up before you start sending your campaigns - or no one will ever see your emails. Pribox can help with that!
