With an ROI of $38 per $1 invested, cold emailing is an effective way of reaching out to prospects. But the recipient will not always read your email which is why you have to craft a striking subject line. You already know that it is the first thing that strikes the eye when a recipient sees their inbox especially when it is an introduction email. In a way, it decides the fate of your cold email campaign. That’s why you have to work on the introduction email subject line.

However, most sales reps are not capable of coming up with subject lines that are good enough. And the problem is that if you cannot capture the prospect’s attention using the subject line, no matter how perfect your email content is, it would all be of no use.

To help you out, we have examples of near-perfect introduction email subject lines lined up for you in this blog post.

What Are Introduction Email Subject Lines?

Introduction Email Subject Lines refer to those subject lines that you craft for introduction emails. In such emails, you reach out to the prospect to build a rapport and a far-fetched goal of closing a deal.  

But before we jump to what the best introduction email subject lines are, let’s know about the importance of a subject line in depth.

Why Cold Email Subject Lines Are Important?

As you have already seen, your email subject line decides your open rate. As per statistics, 47% of individuals determine whether they should open the email or not based on the subject line. And if the prospect doesn’t open your email, there is no chance of making a sale, right? 

There is always a chance to convert the prospect into a paying customer with catchy email subject lines. However, this can be challenging as a person gets hundreds of emails a day, and the chances of the prospect opening your email are less unless it is a priority. That is why you have to put in extra effort to make your subject line stand out.

The chances are scarce if you use the routine generic cold email subject lines. That is probably why the average open rate is as low as 21%. That means 80% of the emails sent go unread by the prospect, which can be pretty disappointing for a salesperson who put in so much effort in crafting emails and taking care of each tiny detail like the CTA and sending time. Also, it can affect the ROI drastically. However, this is part and parcel of the life of a salesperson.

Tips For Writing Eye-Catching Introduction Email Subject Lines

To make your sales email subject lines for an introductory email stand out, you have to keep a few things in mind. Here are the best practices for writing an eye-catching subject for introduction email. Also, learn more about our email subject line generator. 

Introduction Email Subject Line - Infographic

1. Keep your subject line short and catchy

You must try to convey your message in the best possible way while using the minimum number of words. Does it sound challenging? Well, it won’t be if you keep practicing it. Ideally, according to any respected email marketing agency, the length should be around 3-4 words or 7-40 characters in length. It would help to maintain the optimal length because longer subject lines are more likely to get cut off in the preview. The length varies based on the device and the email service provider, but you must try your best to keep the subject line short. After all, your email would be of no use when your subject line gets cut off when it lands in the recipient’s inbox. The person might ignore it or toss it into the trash folder. 

2. Personalize

Time and again, sales experts remind the importance of personalizing emails. Even your subject line should be personalized as the sales email subject lines with the recipient’s name get a 50% higher open rate.

When you choose to personalize your subject line, the recipient feels that the email is relevant to them and would want to open it. You can use the recipient’s first name to give a personal touch. If you don’t want to do so, you can mention something else like the blog they wrote for recently or a common interest you both have. 

3. Keep it interesting

As it is the subject line that decides whether or not the email is worth opening, you have to pay additional to it. You have to make it interesting to read, and for that, you can add elements of what the prospect might care about, which can be a recent development in the industry, a statistic, a project they are working on, etc. You have to keep the subject line customer-centric so that they click to open the email, read it and respond positively. 

4. Mention an offer

Are you offering a product or service that the prospect has been looking for? Do you have a fantastic idea for the recipient? If so, you should mention it in your subject line so that the prospect feels like opening the email. If you can make the prospect’s life easier with your offering, you should not step back from making it evident to them. They will work towards attracting the prospect to your email. 

5. Create a sense of urgency

By creating a sense of urgency, you can make the prospect want to open and read your email. FOMO (fear of missing out) works most of the time. A time-limited deal makes a person not interested in purchasing want to close the deal right away. Though this tactic is effective, you must not depend on it all the time because overdoing it can turn your prospects off. 

6. Be clear

In your introduction email subject line, you have to mention why you are reaching out to the recipient. When the purpose of the email is clear, it will be easier for them to relate to your message. 

7. Say no to clickbait

While click-baiting may look like an easy way to get the recipient to open your email, you must refrain from doing so. Using subject lines that have no connection with the content of the email can tarnish your image forever. When the prospect comes to know that it was a clickbait, they will distance themselves from you and even mark you as spam.

The Best Way To Introduce Yourself In A Cold Email

In an introduction email, you don’t know the prospect, nor do they know you. That is why you have to put your best foot forward in introducing yourself to them. Here’s how you can do that,

1. Use a subject line that draws the prospect’s attention

This is what we already discussed. The email’s subject line decides whether the prospect will open the email or not.  

2. Address your email to a person

If possible, try to address your email to a person to get along with them personally. It is much better than sending an email to [email protected]. The chances of getting ignored are less when you connect to an actual person. 

3. Make use of mutual connections

In an introductory email, it is always better to get a mutual connection in between. Mention the person’s name right at the beginning of your email to get the prospect glued to your email and read on further. The fact is that a referral can make you look more trustworthy, and you should use it for your benefit. 

4. Avoid dictating terms

Making a request is much better than telling the prospect what to do. Nobody likes to be ordered, and if you intend to present your product or service, you have to use a polite tone. Say something like- “Will you be interested in a quick call to discuss this further, if you have the time?” instead of “Please connect with me on a call”

5. Don’t make it too lengthy

What you must never forget is that the current generation is that of skimmers. People don’t want to sit down and read your whole message. They will skim through the email and catch the keywords that strike their eye. If they don’t find anything essential or catchy in the first paragraph, they tend to ignore the email altogether. That is why try to keep your email short and sweet with a maximum of 3 paragraphs. No one has the time or patience to read lengthy essays. StudyCrumb, on the other hand, is a top-rated essay writing service. Being to the point can be a life-saver for you and the prospect.

6. Format the email well

The design and format of your email matter, and for a cold email, you should keep it as simple as you can with a legible font so that the prospect doesn’t find it difficult to read. 

7. Close professionally

Just as the starting of the email is important, so is the email’s closing. Choose to end the email with a clear CTA so that the prospect knows what they should do after reading your email. Add only one CTA to your email to avoid confusing the prospect. 

8. Add an email signature

You can make it easier for the prospect to get in touch with you when you include an email signature. Make sure that you add your name, address, phone number, and social media links. Adding a link to your company’s website is also a good idea as it will lead to more traffic to your site, and the prospect will get to know a bit more about your product or service.

Excel At Crafting Your Introduction Email Subject Line Every Time!

As you are aware that introduction emails and their subject lines hold an exceptional place in your cold email campaign, you should follow the tips and use the examples mentioned above. They will help make your sales email subject lines stand out from the other emails in the prospect’s inbox.
