Words that trigger spam

These are specific words or phrases that can raise red flags for spam filters and negatively impact your email deliverability.

Understanding how spam triggers words work and taking steps to avoid them can significantly improve the chances of your emails reaching the inbox.

Understanding spam trigger words and their impact

The concept of spam trigger words revolves around the idea that certain terms are commonly associated with spam or unwanted promotional content. Every day, approximately 347.3 billion emails are sent out.

Your subject line should avoid trigger words, as well as follow some other best practices to avoid spam. When these words are detected in an email, spam filters may flag them as potentially harmful or irrelevant, diverting them to the recipient’s spam folder or even blocking them entirely.

This can be frustrating for legitimate senders who have valuable content to share.

Common spam trigger words to avoid in emails

It’s essential to familiarize yourself with some of the commonly used spam trigger words and phrases that you should avoid. Here are a few examples:

  • “Free” or “Get rich quick”: These terms often raise suspicions and are commonly associated with scams or misleading offers.
  • “Limited time offer” or “Act now”: While urgency can be effective in marketing, overusing these phrases can trigger spam filters.
  • Excessive use of exclamation marks (!!!): Multiple exclamation marks in a row can be seen as overly promotional or spammy.
  • “Earn money from home” or “Work from home”: These phrases are often associated with dubious or fraudulent schemes, making them trigger spam filters.
  • “Congratulations” or “You’ve won”: Unless the recipient has genuinely won something, using these phrases can make your email appear as unsolicited spam.

Strategies to bypass spam filters

To prevent your emails from being caught by spam filters, it’s important to find alternative languages or strategies that can achieve the same purpose without triggering the filters. Here are a few suggestions:

  • Personalize your emails to cater to individual needs and interests.
  • Provide valuable and informative content that benefits recipients.
  • Use clear and concise language to convey your message effectively.
  • Segment your audience for targeted and relevant email campaigns.
  • Test your emails with spam filter tools to identify and address potential issues.

Weak subject lines

In light of the fact that trigger words can lead to spam, let’s discuss the effect weak subject lines can have on your email open rates and overall deliverability.

Impact on email open rates and deliverability

When it comes to subject lines, they serve as the gateway to your email content. A weak subject line fails to grab recipients’ attention, leading to lower open rates and decreased engagement. It’s like having a fascinating story hidden behind a dull cover – it won’t entice people to open up and explore further.

So, what makes a subject line strong and compelling? Firstly, it should be concise yet intriguing. You want to pique the curiosity of your recipients without giving away too much. Think of it as a sneak peek that leaves them wanting more.

Tips for crafting effective subject lines

Additionally, a strong subject line should be relevant and aligned with the content inside your email. Misleading subject lines may attract initial opens, but they’ll quickly damage your reputation and land you in spam folders. Authenticity is the key here!

Now, let’s dive into some tips to help you craft subject lines that shine and avoid those spam filters:

  • Personalize, personalize, personalize! Including the recipient’s name or referencing their interests creates a sense of connection and boosts the likelihood of your email being opened.
  • Use action-oriented language that encourages recipients to take a specific step. Whether it’s asking a question, offering a solution, or introducing a time-sensitive offer, make it clear what action you want them to take.
  • Keep it short and sweet. Aim for subject lines that are around 40-50 characters in length to ensure they’re fully visible on various devices and don’t get cut off.
  • Avoid spam trigger words we discussed earlier. By steering clear of terms like “free,” “limited time,” or excessive exclamation marks, you’ll reduce the chances of your email ending up in the dreaded spam folder.
  • Test, test, test! Before hitting that send button, run your subject lines through spam filter testing tools. These tools provide insights into how likely your subject line is to trigger spam filters, allowing you to make necessary adjustments.

Sending emails to inactive addresses

You expose your emails to spam by sending them to inactive addresses. Clean your email list regularly by removing inactive addresses to maintain a positive reputation and improve engagement rates. Implement count-based or time-based pruning strategies to ensure you’re targeting active subscribers effectively.

Significance of a clean and engaged email list

Keeping a clean and engaged email list is essential for several reasons. For starters, it helps maintain a positive sender reputation.

Internet Service Providers (ISPs) and email service providers closely monitor engagement metrics like open rates and click-through rates to determine the quality of your emails.

When you consistently send emails to inactive or dormant addresses, it negatively impacts these metrics, potentially leading to lower deliverability rates.

Strategies for managing and purging inactive addresses

By focusing on an engaged audience, you can maximize the impact of your email campaigns and drive better results. So, how can you manage and purge inactive addresses from your email list? Here are some effective strategies to consider:

  • Segment your list based on engagement levels for targeted content delivery.
  • Craft re-engagement campaigns to entice inactive subscribers back.
  • Implement a re-engagement period to assess activity and remove non-responsive subscribers.
  • Use email verification services to maintain a clean and engaged list, reducing bounce rates and spam complaints.

Using large images with little text

Visual content is highly popular in marketing campaigns, with 55% of B2C content creators prioritizing its creation. Marketers often opt for image-heavy emails due to their aesthetic appeal.

Professional-looking emails often incorporate visuals, making them visually appealing and engaging for recipients.

Excessive images in emails: Spam filter impact

When emails contain excessive image content and minimal text, they can trigger spam filters, leading to poor deliverability. To avoid this issue, follow these best practices:

  • Strive for a balanced image-to-text ratio to maintain engagement.
  • Include descriptive alt text for images to improve accessibility.
  • Avoid relying solely on images; incorporate relevant text in your emails.
  • Optimize image loading for faster rendering and better user experience.
  • Test your emails across various platforms to ensure compatibility.
  • By implementing these strategies, you can strike the right balance between visuals and text, improving email deliverability and engagement.

Managing image-to-text ratio in emails

It’s possible to trigger spam filters if emails contain excessive images and little text. As a result, spam filters tend to mark legitimate emails with similar characteristics as spam when they contain images.

As a result, the deliverability of your emails is compromised, with a reduced chance of reaching your intended recipients’ inboxes. It is essential to understand this issue to effectively improve email deliverability and avoid the pitfalls of triggering spam filters.

Best practices for email image usage

To use images effectively in emails while maintaining deliverability, consider the following best practices:

  • Balance image-to-text ratio: Maintain a healthy blend of images and relevant text.
  • Use descriptive alt text: Include text descriptions for images.
  • Diversify your content: Don’t rely solely on images; incorporate meaningful text.
  • Optimize image file size and loading speed: Compress and optimize images for faster loading.
  • Test across different devices and email clients: Ensure proper rendering on various platforms.

Attachments included

Attachments should be avoided for two reasons:

  • First, they trigger spam filters and hinder email deliverability.
  • Second, attachments can slow down the load time of emails.

Instead of using attachments, it is recommended to include all necessary information, offers, and calls to action directly in the email body. If you want to share a video, consider inserting a screenshot linked to the online location where the video is hosted.

Challenges and risks of email attachments

When it comes to sending emails, using attachments can pose various challenges and risks that are important to consider. Here are the key points to keep in mind:

  • Explore alternative methods for sharing files or critical information
  • Utilize secure download links or cloud storage platforms
  • Embed images or screenshots directly in the email body
  • Use hyperlinks to relevant web pages or online resources

Attachments and spam filters: A closer look

Attachments can trigger spam filters or raise suspicion among recipients due to the following reasons:

  • Security concerns: Attachments can be perceived as potential security threats, as they may contain viruses or malware. Spam filters are designed to identify and block suspicious attachments to protect recipients from potential harm.
  • File types: Certain file types commonly associated with malicious content, such as .exe or .zip files, are more likely to trigger spam filters or raise red flags among recipients. This is done as a precautionary measure to prevent potential threats.
  • Unknown senders: Attachments from unknown or untrusted senders can create suspicion. Recipients may hesitate to open attachments from unfamiliar sources, fearing potential risks to their devices or personal information.


In conclusion, to improve email deliverability and reach recipients effectively, it is crucial to understand and address the common reasons for emails ending up in spam folders.
