1. Email Subject
One of the crucial elements in email communication is the subject line. It's the make-or-break factor that determines whether your email gets opened or not. Here are some principles for a compelling subject line:
First, keep it short and enticing. Strive for brevity while conveying the main point of the message. Second, write the subject last, after completing the email content. Identify all key elements in the email, then search for interesting themes to emphasize in the subject line. After writing the email content, reread it and choose compelling words to pique the reader's curiosity.
In summary, the email subject serves to summarize the content and decide whether the recipient opens it. Therefore, it needs to be attention-grabbing, sparking curiosity, and avoiding words that may trigger spam filters, such as: hot, best, all caps, etc.


2. Utilize Numbers or Characters at the Beginning of Lines
When your article has various elements to express, use numbers or characters to break down the content, organize it clearly for your readers who are your customers to easily understand and provide clear responses. Avoid listing them consecutively, as this will make it challenging for readers to provide organized feedback.
You can use: a) b) c) or 1) 2) 3) and many other characters readily available on your keyboard. However, choose simple, uncomplicated characters to purposefully break down dense emails, making the content clearer and helping readers respond to you easily.


3. Email Content
To have an effective email for customers, strive to compose content that is as concise as possible. Focus on the message you need to convey, avoiding unnecessary details unless the email is for explanation or providing reasons. Being brief and to the point will determine the appeal to your customers.
Some factors to consider in establishing professional, perfect, and engaging email content for customers:
- First: Keep the content concise while still conveying your information; too many words or excessive length will make customers immediately exit your email
- Second: Use colored elements in the font to emphasize what you want to convey. However, avoid using too many colors to prevent eye strain. Use vibrant red or ocean blue to bold and enlarge what you want to say to customers. Use a maximum of 2 - 3 colors for representation
- Third: Avoid spelling errors, do not overuse italics, underlining, and inserting links.


4. Images in Email Content
If your article is illustrated with images, it undoubtedly enhances the vibrancy or serves as evidence for what you write in the email. Ensure that the images you use are the most easily understandable for customers.
However, when using images, pay attention to the size and name of the images. Oversized images make it difficult for customers to load your email, while overly small images may go unnoticed. The number of images should be limited to no more than 5; an excessive number of images may have a counterproductive effect.


5. Embedding Links in Email
Sometimes, the content you send in your email is just a brief overview of what you want to convey to customers. Therefore, lead them to your main website to add detail and specificity to the content you want to convey.
However, when leading links, it's crucial to direct them to your company's or product's own website, as it is a prerequisite for email marketing. Advertising via email where customers cannot contact or access your website can reduce sales potential because the website validates what your email says!
But there's a challenge; many customers inserting website links or attaching hyperlinks when sending emails may end up in spam folders. In a mass email, when you send to thousands of customers, the first thing Google's search filter looks for in the email content to evaluate spam is the link.

6. Exercise Caution with Attached Files in Email
Choosing an attachment is the final part of an email; attach a quote or the content you want to present. Attach files in a format that customers can download and read easily. Pay attention to the name of the attached file to match the content.
Currently, file formats like PDF and MS Word are common ways to share profiles, with Google Documents becoming increasingly popular. Choose the content of the attached file to align with the article content, thereby expressing your ideas in the content you want to send to customers.


7. Clearly Articulate Requests and Friendly Content
When exchanging information via email, vague terms can easily lead to confusion. Avoid using ambiguous words; instead, clarify what you want the reader to do and when accurately. To enhance the persuasive effectiveness of the email.
Additionally, you need to have friendly content. Limit self-promotion in your email to avoid losing favor with customers. For example, if you want to say, “I work with technology to create tools. Sometimes, we post it on Facebook and Instagram.”
But instead, you write in your email: “I collaborate with multifunctional teams to implement cross-channel communication strategies that drive the best multi-platform content production, resulting in optimal viewer interaction and retention.” Therefore, write friendly content, limiting self-promotion.


8. Avoid Using Words with Spam Risks
Whether you like it or not, your email can still end up in the Spam filter and reside in the user's junk mailbox. To address this issue, avoid using language that may be misunderstood and marked as spam by Google. There are many reasons why emails end up in the spam folder. Besides issues related to the quality of the email service provider, email lists, the email filter also scans the email content to determine whether to place it in the inbox or spam folder.
Some words that may trigger spam:
- Phrases like: “Click here”, “Once in a lifetime opportunity”, “Buy now”…
- Using too many exclamation marks “!!!!” in the email
- Email content with multiple colored fonts
- Using only 1 large image without / with little conveying text


9. Focus on Personalization
A personalized email copy will perform better than a generic one. Therefore, add the customer's name to the email subject to make them feel your respect for them. This will encourage them to open the email and see what's inside.
To stand out among other emails, ensure full personalization, making them different from your competitors' emails.
