What are email spam words?
Email spam words are phrases or keywords in your subject line and email copy that email providers mark as malicious or spammy. These words activate the spam filters, causing your emails to land in the user's spam folder instead of their inbox.
Apart from the words, the context also matters.
As spam filters are getting more advanced, they won't automatically send your emails to spam if they contain words like "discount code" or "claim your offer." But, you'll be in trouble if you.
- Stuff plenty of spammy keywords.
- Use lots of emojis exclamations.
- Use all capslock, bright red fonts.
The image below reflects the spam words used in the subject line, which is why this email landed in the spam folder. Other than that, in the beginning, the sender is using all caps lock, which is another red flag.
Spam words are just one of many factors that land email in the junk folder, impacting the campaign’s deliverability.

To foolproof your emails from email spam words, you can run the copy and subject line through these spam checker tools:
1. Mail Meteor spam checker

This detailed breakdown helps you identify and remove such words.
2. Email tooler spam word analysis

Additional tips to stay out of the email spam folder
Here are 5 crucial tips you should follow to pass through spam filters:
• Ensure emails are authenticated: SPF, DKIM, and DMARC
If your email passes through the email authentication protocols, the chances of getting to the recipient's inbox increase. These protocols signal internet service providers (ISP) that your emails are sent from a legitimate domain by an authenticated sender and don't have any spammy content.
Sender Policy Framework (SPF): SPF ensures that you send emails from an authenticated domain, not a relay server.
Domain Keys Identified Mail (DKIM): DKIM is an email security standard that ensures messages are not modified while traveling between the recipient and sending servers.
Domain-based Message Authentication, Reporting & Conformance (DMARC): DMARC is the actionable protocol. It means DMARC will take action when DKIM/SPF fails on your sender’s domain.
• Monitor your IP reputation
A low IP reputation can be due to IP blacklisting, getting hit by spam traps, or sending a high volume of emails without proper warmup. All these factors work as a red flag, triggering the ISP’s spam filters.
So, you must keep an eye on your IP reputation using tools like Google Postmaster or MxToolBox.
• Maintain a higher domain reputation
A higher domain reputation would mean that emails from your sender domain are less likely to be trapped in the email provider’s spam filters. Hence, you will get higher deliverability.
To monitor your domain reputation, you can use the Google postmaster tool and get insights into how your domain performs among Gmail users.
• Practices email list hygiene
Email list building is crucial for reaching out to your subscribers but cleaning it consistently to maintain a healthy email list rate is equally essential. A healthy or hygienic email list is when you remove unsubscribed users so that you don’t accidentally send them emails and risk landing in the spam folder.
Besides, you should also suppress inactive and unengaged users by implementing a sunset policy to avoid sending them emails despite their disengagement.
• Make your emails engaging and relevant
Besides the technicalities, if your emails are relevant to the recipient, they will either unsubscribe or stop interacting. This leads to lower open and clicks rates signaling ISPs that you might be sending irrelevant emails. So, put yourself in your audience’s shoes, study their pain points, and behavior, and use that data to create emails that add value.
Conclusion
It’s a horrible feeling to see all your time, efforts, and resources getting hit by the spam train just because you weren’t aware of the words that might trigger the spam words.
But, now you have the list which you can refer to while writing your emails. Always keep this list handy and you’ll see higher open rates.
