Have you ever stared at a blank screen, not knowing what to write? 

From the subject line to the signature, each element plays a vital role in conveying your messages effectively. How you use these email parts will impact your campaign metrics and overall performance.

Join us as we decode the anatomy of an email and interpret its components to help you navigate email marketing with ease and efficiency.

The Main Parts of an Email 

An email may seem like a simple thing at first glance, but it contains complex parts that come together to achieve the desired outcome. In commercial email business, this means each component is critical to increasing your open rates and conversions.

Let’s break down the different email parts and present them in a table for better viewing.

Understanding each component helps you create targeted communication that increases the likelihood of engagement. 

Why Are Different Email Components Important?

It can be tricky to strike the right balance between different email components, especially when conveying urgency without resorting to spammy language.

When done well, each part of an email can help avoid confusion for you and your recipients. They enhance the whole look and feel of your emails, allowing you to instill your brand image.

Each component plays a crucial role, as follows:

  • Sender’s email address: This identifies the sender, establishing trust and credibility. Knowing who the email is from also helps recipients prioritize their emails accordingly.
  • Subject line: This is the first impression of your email. Crafting informative and engaging subject lines can entice recipients to open your emails and understand them quickly.
  • Preheader: The preheader complements the subject line by providing additional information about the email.
  • Greeting: A proper greeting line establishes a connection with your recipients, helping you strike a professional and friendly tone at the same time.
  • Email body copy: This is what your email actually is — the main content. Whether it’s email coupons or event invitations, the email copy must elaborate on it.
  • CTA: The call-to-action guides readers toward the next steps. It also decides if the recipients will act on it; whether it’s signing up for your email list or purchasing products.
  • The footer: This is where you provide essential brand information and follow legal compliance, such as the unsubscribe button
  • Attachments: This further shares complex information such as data, visuals, and other files that wouldn’t comfortably fit in the email body.

Mastering the email components and constructing them thoughtfully will help you gain the trust of your recipients and make your emails stand out in the inbox.

To make it easier for you, we’ll explore the different email parts along with their best practices.

The Header — Sender/From 

The sender or ‘From’ field is the initial point of contact and is the first thing people notice. It also helps recipients decide whether the email is safe to open.

The header is important for several reasons because it:

  1. Identifies the sender: It informs the recipients about who sent the email, increasing transparency and legitimacy. The header acts as a cornerstone of your identity in establishing trust and credibility. 
  2. Builds brand recognition: The ‘From’ field is an opportunity to reinforce branding and identity for businesses. Consistency across sender names will help recipients recognize and associate messages with your brand, fostering brand loyalty.
  3. Develops clarity and authenticity: Whether it’s an individual’s name or company address, the sender name establishes authenticity.
  4. Builds relationships: Personalized ‘From’ fields build rapport and strengthen customer relationships. 
  5. Helps filter and organize emails: Consistent sender names help recipients set up rules to prioritize, categorize, and filter emails.

Email Header Best Practices

  • Use a recognizable name: Avoid using generic names like “Notification Center” or “Admin Team.” Use an individual or company name to send your emails.
  • Maintain consistency: Use the same email address for all your email campaigns to establish brand recognition and trust.
  • Be transparent: Avoid using misleading or deceptive sender names such as  “Do not reply” or “Automated message.”

To summarize, the sender name is not just a technical aspect of email communication, but it ensures clarity and builds trust with recipients.

The Subject Line: Captivating Audiences’ Attention and Interest 

The subject line is arguably the single most crucial element of an email that determines your open rates. After the sender’s name, recipients check the subject line for relevancy and authenticity.

Be careful what you write in the subject line — using too many symbols or inappropriate words can trigger spam filters and tarnish your sender reputation.

The subject line impacts your campaigns in the following ways:

  1. Influences open rates: A compelling subject line can entice readers to open your emails and boost conversions.
  2. Sets the tone for the email: It creates anticipation and provides an overview of the email content.
  3. Encourages action: Subject lines with time-sensitive discounts and deals encourage readers to take prompt action.
  4. Enhances uniqueness: Well-crafted subject lines captivate audience interest and differentiate your brand in a crowded inbox.

Tips to Craft Captivating Subject Lines

  • Impose clarity over cleverness: While being witty can be helpful, ensure your recipients understand the purpose of the email.
  • Keep it concise: Aim to keep them within 50 characters for full visibility across devices.
  • Personalize when possible: Include the recipient’s name or personal details whenever possible.
  • Create urgency and scarcity: Use words such as “Buy now” or “Limited time offer” to get people to act quickly.

Further, consider segmenting your audiences to create tailored subject lines and improve relevance.

The Preheader: A Way to Boost Open Rates Even More

The preheader comes with the subject line; consider it an extended version that complements the existing message.

It’s a short line of text displayed along with the subject line in most email clients. While its length can vary, it typically shows the first two lines of the email body copy — more like a trailer to your email content.

Often overlooked, the preheader offers a brief glimpse into the email content and can impact the success of your email campaigns

You might be amazed by how these little snippets can help:

  1. Clarify the email’s purpose: By providing further details, the preheader text can pique customer curiosity and paint a clearer view of the email.
  2. Increase open rates: A compelling preheader can act as a mini-CTA, urging the customers to click on the email and learn more.
  3. Enhance brand consistency: A consistent tone and style of the preheader and subject line strengthens the brand image and establishes a professional and recognizable place in the recipient inboxes.
  4. Improve deliverability: Preheaders can indirectly impact email deliverability by increasing open rates. A few ESPs consider engagement metrics like open rates when filtering spam, so a well-written preheader can make your emails look legitimate.

Tips to Create Effective Preheaders

  • Keep it brief: Keep your preheaders 40-50 characters long.
  • Be specific: Briefly summarize the email content or highlight key points.
  • Maintain brand voice: Ensure the preheader’s tone aligns with your brand personality and voice.

Salutation: Personalizing Relationships With Customers

A simple “Dear” or “Hello” before the recipient’s name can make your emails feel more special — they help you personalize messages and build stronger customer relationships.

Greeting recipients by their names creates a deeper bond and encourages them to continue doing business with you. 

Personalized salutation also leads to:

  1. Enhanced engagement: A personalized greeting immediately catches the recipient’s attention and shows that you’ve put effort into building a connection.
  2. Established trust and credibility: Using the recipient’s name shows that you value them and have taken the time to learn about them.
  3. Sets the tone: Personalizing salutations creates a warmer and friendlier tone, fostering an open communication style.

Tips to Use Better Salutations

  • Avoid generic greetings: Don’t use terms like “To whom it may concern” or “Dear sir/madam.” These can come off as cold and disrespectful.
  • Consider the context: Tailor your salutation based on the email; professional or personal.
  • Be casual: If it’s in line with your brand image, don’t be afraid to use casual salutations and language.   

The Email Body: The Heart and Soul of Your Email Communication

The email body is where your purpose unfolds — provide subscribers with valuable content, offers, and updates.

Since people generally tend to have a short attention span, aim for crisp and valuable paragraphs organized with bullets and numbers. You can also use email copywriting principles to enhance the tone and feel of your messages.

Remember, the goal is to convey the message promptly in return for an action, such as signups, purchases, etc.

To-the-point email body can have the following benefits:

  1. Makes it easier to understand messages: A concise email body breaks down complex segments into readable content.
  2. Sets up tone and style: Your language, tone, and the length of the email body explain your brand personality and set the tone for future emails.
  3. Drives action: When you aim to elicit a response or simply share information, the email body is where you nudge recipients to take the desired action.

Creating Engaging Email Content, Tips and Ideas

  • Start with a strong opening: Begin your email with a clear and engaging sentence setting the tone for the entire email.
  • Structure your content logically: Whether it’s discounts or educational content, split the content into sections.
  • Focus on the benefits: State the benefits of your email; whether it’s buying your products or signing up for your newsletter.

Call-to-action: Drives Action and Engagement

The call-to-action is the extension of your email body message — both must align to get a response from your customers.

The CTA is more like the ignition switch that turns passive readers into active customers. That’s why your CTAs must be intriguing enough for readers to click and take action.

Crafting a compelling CTA will help you:

  1. Drive the desired action: CTAs provide clear and actionable instructions, guiding readers to the next steps.
  2. Boost engagement: A well-done CTA can encourage people to learn more about your brand, increasing your email engagement metrics.
  3. Measure success: CTA serves as a valuable tool to understand conversions and ROI. Analyzing these metrics will help you gauge the effectiveness of your email campaigns.

Writing Effective CTAs

  • Use action-oriented language: Utilize strong verbs that inspire action, such as “Download” and “Buy now.”
  • Use contrast colors: Make your CTAs stand out using different colors and fonts.
  • Align with your goals: Ensure your CTA guides recipients toward the desired goal.

The Footer: Save Your Sender Reputation

The email footer is where you mention relevant details such as your contact information, social media links, legal disclaimer, and most importantly, the unsubscribe option.

Providing an unsubscribe option is mandatory according to the CAN-SPAM and GDPR Act. When people can’t unsubscribe easily, they will report your emails as spam, leading to a low sender reputation score.

At Campaign Refinery, we understand the importance of your sender reputation, and that’s why all the emails our clients send include an unsubscribe option by default.

Why is a well-crafted footer necessary? Because it:

  1. Provides essential information: The footer has adequate company information, allowing users to connect with you outside of emails.
  2. Complies with legal requirements: Legal disclaimers and unsubcribe options help you stay out of trouble by following email marketing best practices.
  3. Protects sender reputation: Clearly labeled opt-out options can increase trust and credibility with ISPs and prevent your future emails from going to the spam folders.

Email Footer Example

Email Footer Best Practices

  • Use links: Provide links to your social media, websites, etc.
  • Unsubscribe option: Always provide an opt-out option that’s easy to find.
  • Contact information: Provide simple ways to contact you.

A well-crafted footer adds a touch of professionalism and increases transparency in communication.

Attachments: Enhance Collaboration and Communication

Attachments are powerhouse tools that help you collaborate and send additional information without cluttering the email.

For example, a project proposal email will contain a brief introduction to the project and a detailed document with budget, scope, etc, as attachments. Attaching documents, videos, and texts makes it easier for recipients to download and revisit the content when needed.

Here are more reasons why attachments are necessary:

  • Helps share complex data: Whether it’s e-tickets, illustrations, or a detailed tax document, attachments help you seamlessly share complex data.
  • Enhances clarity and understanding: Visual aids such as infographics, charts, etc, can help the readers understand the content better than text alone.
  • Supports the email body: Attachments act as support documents, strengthening the message and enhancing impact.

Your attachments can be any size, but ensure to use a cloud-based platform to upload bulk documents, especially for larger-sized files.

Other Tips to Remember

  • Mention attachments: Briefly reference the attached files in the email body for extra clarity.
  • Maintain security awareness: Urge your subscribers to whitelist your email address and only download attachments from trusted senders.
