1. Subject Line – Drawing Attention

A subject line is the first impression you leave in your recipient’s inbox. A clear subject line quickly grabs attention and sets the tone for your email.

It’s especially crucial in cold emails, where you must craft the essential elements carefully to stand out. The best subject lines increase user actions. It ensures your message gets opened instead of ignored.

However, a poorly written subject line can cause your email to be marked as spam or overlooked.

Including essential information and maintaining the right tone helps improve engagement and avoid the spam folder.

To craft a compelling subject line you can implement these methods:

i. Personalization and Relevance

When you personalize your subject line, you make your recipient feel like the email was crafted just for them. Using their name, job title, or interests grabs their attention instantly.

A well-personalization within the email marketing components shows that you understand their needs, making them feel valued.

This small effort increases the chances of them opening your email and engaging with your message.

ii. Length and Clarity

You want your subject line to be clear and to the point so your recipient understands your message at a glance.

Keep it between 4-9 words and under 40-70 characters to ensure it displays properly across all devices.

Most email clients cut off subject lines after 50 characters on mobile and 70 on a PC, so shorter is better.

A well-optimized email component helps you avoid confusion and keeps your message focused, making it easier for your recipient to engage.

ii. Avoidance of Spam Trigger Words

Certain words like “free,” “discount,” and “limited-time” can trigger spam filters, making your emails look like typical marketing material. These terms can reduce your chances of landing in the recipient’s inbox.

If you send too many emails with these words, especially without warming up your SMTP, your emails may end up in the spam folder. It’s crucial to avoid overusing such terms in your subject lines.

Instead, make your subject lines personal and relevant to the recipient. For example, “Thought you’d find this research useful for your project, [First name]” makes your email feel more personalized and valuable.

2. Pre-header – Supplementing the Subject Line

The pre-header gives you a chance to show your recipients a glimpse of what they can expect from the email content, almost like a teaser.

It’s a great way to expand on the subject line and capture their interest right away. The pre-header appears on certain email providers, like Gmail or mobile devices, next to the subject line in the inbox.

If you don’t set a pre-header, the first line of the email content will show, which can sometimes confuse the recipient without them opening the email first.

Email experts recommend using a pre-header because it acts like a call to action, encouraging your recipients to open the email. It helps create a stronger connection with them and improves engagement.

Optimizing Pre-header Text for Engagement

Here are some tips for optimizing your email pre-header for the best engagement rate:

• Use no more than 40-50 characters to ensure maximum visibility.
• Tease the email, but don’t give out everything.
• Add unique value and benefits that subscribers will gain by opening the email.
• Incorporate a clear and compelling call to action in your pre-header text.
• Add personalization if possible to give the email a friendly touch.
• A/B tests different pre-header variations and identifies the most effective ones for your email campaigns.

3. Branded Header Graphic – Visual Identity

When preparing the body of your email, starting with a header graphic that reflects your branding is a great way to create excitement and remind your recipient who you are.

A well-designed header grabs attention and sets the tone for the rest of the email. It also helps the receiver connect with your message.

Make sure to include brand elements like your brand colors and logo in the header graphic. This helps ensure immediate recognition and reinforces your identity.

Using a consistent header graphic in line with RFC 5322 and RFC 6531 guidelines can prevent delivery issues and improve email composition, especially when considering internationalized domain names.

Incorporating these visual cues alongside social media links, embedded media, and sender details enhances the overall email experience, making it easy for your audience to recognize and engage with your content.

4. Main Message – Core Content Delivery

The core of your email is the message you want to communicate to your recipient. Email copywriting is the key to convincing them to take the action you desire, focusing on how it benefits them.

Keep in mind that your email copy should make the recipient feel important and motivated to act. Make sure to highlight the value for them, and keep the message clear with a strong call to action.

Use emotional triggers, such as urgency or FOMO, to create a sense of necessity. Be direct and ensure your message is easy to understand, with no room for confusion.

Ultimately, the goal is to deliver a message that makes your reader feel valued and excited to take the next step, whether it’s purchasing, signing up, or engaging.

5. Call-to-Action (CTA) – Driving Engagement

A CTA is a clear prompt directing readers what action to take such as “Register Here” or “Learn More.”

Carefully crafted CTAs can influence your engagement. Place CTAs strategically to guide your buyers to take action or respond.

To craft a compelling CTA, you can focus on the placement and the CTA text.

placement and design of your CTA are crucial in ensuring it grabs your reader’s attention. A well-designed CTA is more likely to be noticed when it stands out from the rest of the body content.

You can achieve this by using contrasting colors, larger fonts, bold text, and distinctive button shapes. These design elements make your CTA more visible and easier for readers to spot quickly.

ii. Action-Oriented Language

When crafting your CTAs, use action-oriented language that tells you what to do next. Phrases like “Apply Now,” “Download,” or “Register” are direct and compelling, pushing you to take immediate action.

The supporting message is a key part of your email anatomy that can greatly enhance its value.

While it’s valuable for you to include this extra content, make sure it doesn’t overshadow the CTA. Leave enough space after the main action button so readers stay focused on what you want them to do next.

In some cases, if you feel the supporting message might distract from the CTA, it’s okay to skip it and keep the focus sharp.

7. Footer – End of Email with Business Reference

The footer marks the end of your email in a professional, organized way. It often includes essential business details, like contact information, legal disclaimers, and unsubscribe options.

If a signature might shift focus away from your CTA, it’s often better to skip it. Keeping the attention on your call to action can improve your click-through rates.
