Benefits of Email Marketing

Let’s have a look at some of the major benefits of Email Marketing:

1. It’s inexpensive

Email Marketing is one of the least expensive marketing options available. It is an economical source of advertising and promotions. You can send out an email to thousands of people in a very short time with a small investment. The cost of an email marketing platform depends on the features, but it can be as low as $5 per month. For example, MailChimp offers free accounts for up to 2,000 subscribers and 12,000 emails per month. However, after 12,000 emails per month, you’ll be charged $2 per month for up to 25,000 subscribers and $10 per month for up to 100,000 subscribers.

2. It’s easy to get started

You don’t have to have any technical knowledge or coding experience to set up a basic email marketing campaign. Many email marketing services offer step-by-step instructions and a variety of templates you can use to create your first campaign.

3. It’s simple and easy

Email Marketing is very simple and easy to do. All you need to do is send out your ads or promotions in a newsletter format to your customers or potential customers. So whether you’re promoting a product or service, a free giveaway, or even if it’s simply an update on your company, Email Marketing is a great way to get the information out there.

4. It’s fast and instant

Email Marketing is the fastest way to reach your customers. It’s faster than print ads, TV or radio advertisements, and even direct mail. Once you’ve set up your campaign, thousands of people can see your ads within minutes. The time between hitting “send” and having your ad seen by a customer is astonishingly fast.

5. It’s measurable

With Email Marketing, you will know your target audience, how many people received it, and who opened your email. You can also track which links your customers clicked on, how often they opened your emails, and which links they clicked on in your emails.

6. It’s interactive

The best part about Email Marketing is that it’s interactive. You can send out an email to your customers or potential customers, and then you can follow up with them via phone, email, or even a face-to-face meeting. When your customers are engaged with your brand, they are more likely to buy from you, recommend you to a friend, or even become faithful customers for life.

7. It’s mobile

With the increase in mobile use, Email Marketing is a great way to reach your audience on the go. They can see your ads and promotions, even if they’re not at home or in the office, as long as they have their mobile device.

8. It’s personal

When you send an email to a large group, it comes across as impersonal. However, when you send an email to one person, it’s very personal. This is because emails are sent to people directly, and they are not broadcast to a large group of people.

9. It’s cost-effective

Email Marketing is relatively inexpensive compared to other forms of marketing. The costs are low, and you can generally do it yourself. It doesn’t require much time or money, so it’s easy to start.

10. It’s trackable

Email Marketing is a very trackable method of advertising. You can see which emails were read, who opened them, and which links they clicked on. This information will help you to target your audience better.

11. It’s quick

With Email Marketing, you can send out a newsletter, ad, or promotion and have it in front of your customers within minutes. It’s one of the fastest ways to reach your customers.

Many different platforms are available for Email Marketing, but MailChimp is one of the most popular. It offers many great features for small businesses, including email templates, a drag-and-drop email builder, A/B testing, and more.

How to Write the Perfect Subject Lines

There are three main factors that you should consider when crafting the perfect email subject lines for your email campaigns:

  • Subject Line Length
  • Subject Line Personalization
  • Subject Line Relevance

1. Subject Line Length

One of the most common mistakes in writing great subject lines is not giving enough thought to length. Many people think longer subject lines are better, but this isn’t always the case!

Most email marketing services suggest keeping your subject lines under 60 characters to ensure they are compatible with most inboxes and don’t get cut off. However, we’ve found that it’s not just length that matters but also how you use your space.

For example, if you have a long subject line that is only 25 characters long and is jam-packed with keywords and phrases, your content will likely be cut off in the inbox. Remember, your goal is to keep your subscribers engaged, so don’t risk losing them by stuffing your subject lines with too much information!

2. Subject Line Personalization

Personalizing your subject lines is another common mistake that many people make. Although personalization can be a great way to stand out from the crowd, it’s important only to use a subscriber’s name or email address if you have their permission. Otherwise, they may mark your email as spam.

3. Subject Line Relevance

Relevance is one of the most important factors in crafting great subject lines. As we discussed above, it’s important to understand your email’s goal before creating your subject line. The same goes for your subscribers.

If your subscribers know what to expect from your emails, they are more likely to open them. So make sure you use subject lines relevant to your email’s content. For example, if you’re sending an email with a link to an article, use a subject line that references the article’s topic.

What Is Your Email Marketing Subject Lines Goal

One of the most important factors in writing subject lines is understanding your email’s goal. This is key because, as you’ll see below, there are different types of subject lines that work best based on your email’s goal.

For example, if you want to increase your email’s open rate and encourage subscribers to click through to your website, you should write subject lines that provide value and trigger a desire to click. However, if you want to encourage subscribers to take action, like unsubscribing from your list, you should use subject lines that direct subscribers to take action.


Here are a few examples of common email goals and the subject lines that work best to achieve them:

1. Increase Open Rates

Your goal is to get your email open to subscribers. Here’s how to do it:

Use subject lines that create curiosity, offer value, or provide information subscribers want to read.

Examples of open-rate-focused subject lines include:

  • “Did you miss this?”
  • “We have something important to share with you.”
  • “Do you want to miss this?”

2. Trigger Click-Throughs to Your Website or Landing Page

Your goal is to get subscribers to click through to your website or landing page. Here’s how to do it:

Use subject lines that offer subscribers valuable information, indicate a time-sensitive opportunity, or encourage subscriber action.

Examples of click-through-focused subject lines include:

  • “Only X left in stock!”
  • “You must read this before you leave for vacation!”
  • “Don’t forget to check out this awesome new feature!”

3. Increase Subscriber Engagement

Your goal is to engage subscribers and drive them to take action. Here’s how to do it:

Use subject lines that provide value or suggest a desirable outcome of taking the desired action.

Examples of subscriber engagement-focused subject lines include:

  • “Are you making these mistakes with your email marketing?”
  • “You’ll never guess what happened when we tried this!”
  • “Did you know…?”

4. Increase Unsubscribes or Reduce Spam Complaints

Your goal is to reduce the number of subscribers who unsubscribe or complain about your emails being spam. Here’s how to do it:

Use subject lines that encourage subscribers to take action, such as unsubscribing.

Examples of action-oriented subject lines include:

  • “Unsubscribe me from this list.”
  • “Please remove me from this list.”
  • “Please stop sending me emails.”

Subject Line Best Practices

While there are many different types of subject lines that you can use in your email campaigns, there are a few best practices that apply to all of them. Use these tips to write the best subject lines for your email campaigns:

  • Keep Them Short: As mentioned above, most email marketing services recommend keeping your subject lines under 60 characters. However, the best subject lines are usually shorter than that to cut down on inbox clutter.
  • Use Numbers: Numbers in subject lines grab attention and encourage clicks. They also help your email stand out from the crowd.
  • Use Emojis: Emojis in subject lines are a great way to add personality to your subject line while also drawing attention to it. They also make your subject lines easier to read, which is especially helpful if they are long.
  • Use Action Verbs: Action verbs (verbs that indicate action) such as “learn,” “see,” “discover,” “uncover,” “unlock,” and “discover” are great for encouraging click-throughs or encouraging subscribers to take action.


Email subject lines are critical to your email marketing campaign’s success. It sets the tone for the rest of the email; the subject line is your first chance to catch someone’s attention. Ideally, you’ll want a subject line that is clever or catchy but that also provides a sense of urgency or provides enough information to pique someone’s interest. The subject line is your biggest chance to grab someone’s attention as they scroll through their inbox, so use it wisely.
