Email subject lines are the common crucial factor in deciding whether or not a recipient will open your email. Here are some tips to help you reach out from the crowd and increase your email open rates!

People are continually being attacked by emails every day, which means it’s becoming more and more challenging for email marketers to get regarded among all of the competition and influence readers to open their message.

The most obvious, and arguably the most important, factor that contacts see for your email campaign is the email subject line. This also makes it the main factor that you can squeeze to improve your open rate and get higher engagement when sending an email newsletter or bulk email campaign.

In this article, we’ll give you some tips to help you build email subject lines that will:

  • Grab readers’ awareness
  • Convey a more powerful quality level of content in your message
  • Induce recipients to open

1. Keep it Short

A great email subject line should be rather short to keep the reader’s attention and evade being trimmed by email clients.

In theory, there is no precise limit to the length of your email subject line (though some tools will place their own limit on how much you can input to the field). In actuality, long subject lines will nevermore be read in full anyway because several email inbox software providers are only competent in performing a certain number of characters before the text is cut off.

2. Put the Common Essential Information First

Highlight the most important information that you want to communicate upfront in your subject line to maximize the chances that people want to engage with your content.

For the identical reasons that you want to keep the subject line short, you should also put the most relevant information first. Since you have no control over the number of characters that will be presented to the reader, the only thing you can do is highlight what you want upfront so they have the highest likelihood of seeing it.

Additionally, users manage to only take a glimpse at the subject line, so the first few words are where you want to catch their attention with the usual valuable stuff.

By “important,” I mean anything that will effectively capture the reader’s consideration quickly:

  • The central point of your email
  • Features about a promotional discount
  • A date or time goal showing urgency
  • An interesting phrase that bothers the reader’s interest

3. Withdraw using Spam Words

Spam words are the words that email inbox providers use to verify whether a message is spam — and they also regularly give readers a bad opinion of your email as well!

The last thing you want is an email marketer is to be recognized as a spammer by your audience. But, depending on the language you use in your email subject lines and message, your readers might be thinking just that.

Some words that are known to be connected with spamming can often trigger a feeling of uncertainty among recipients, and even worse, they can manage email inbox providers like Mailcot transfer your emails straight to the spam folder. These words include things like:

  • Free
  • Promotion
  • Hot
  • Casino
  • Urgent

I guess you get the idea. If you can, try to avoid using this type of language, particularly in your email subject lines because it will likely hurt your campaign’s action rate.

4. Spice Things up with using Emojis

When used with individual care, emojis can give your email subject lines more clarity in the inbox, making it more powerful and attractive to possible readers.

Like any marketing advice, you need to first consider your audience before combining this tip into your email marketing strategy. You don’t want to give the opposite result. For example, if you’re a financial advisor, your clients might not want to see a smiley face in the subject line of your emails! However, if your brand has a smaller marketing strategy, then emojis could be the ideal way to supercharge your email subject line and increase your open rates.

Not only are emojis great for fast communicating an idea with fewer characters — making your subject line more concise and leaving you more room for other information — but they also help you accurately stand out from other subject lines that only include text.

Which subject line stands out most from the crowd?

You can also get around the problem of communicating information ordering spam words — just substitute them with emojis!

  • ⏲ can replace “urgent”
  • ? can replace “gift”
  • ? can replace “hot” or send the demand for some items

But, be careful when you start including emojis in your emails and subject lines! Depending on the device and the email client, emojis may be performed separately. To make sure you’re getting it right.

5. Maintain it Simple and Professional

Next steps

Don’t overload it with unnecessary capitalization, unique characters, or punctuation in your email subject lines.

Just because something helps you stand out in the inbox doesn’t certainly mean it’s a good idea to perform in your subject lines! Sometimes, quick “hacks” that might, in theory, give you more visibility can actually have very negative results.

For example, including things like, “EXCLUSIVE OFFER” and “LIMITED TIME ONLY,” or you add too many special characters, such as “SAVE $$$$,” you could actually end up being classified as spam.

And even if you make it to the inbox, this type of email subject line content isn’t likely to leave a vast impact on your contacts.

If your subject line creates a higher open rate but hurts the relationship and trust that you have with contacts, it’s time to go back to the drawing board.

This is apparently the most valuable tip I can give you: a good email subject line isn’t just centered on maximizing the open rate of your email campaign. It should also build trust and set your email up for success in terms of engagement and conversion (hopefully you want people to do more than just open ? ).

Evading clickbait tactics or other things focused on short-term gains is the best way to accomplish this and continue strengthening your contact relationships.

The most simple example of this in action is when a subject line creates unreal expectations that are finally not met by the email content. Design is a very powerful sentiment, but you need to make sure that you give the reader the wrong idea. An example of this would be using a subject line like, “You’ll never guess what we’ve got for you!” for an email that simply promotes a new product.

This type of communication can really hurt your brand in the eyes of your contacts, so you have to be very careful and always take a customer-first strategy.
