What are spam trigger words?

Spam trigger words are basically red flags for email providers. They are words or phrases that typically appear in spam emails and can send your email to the junk folder instead of your inbox.

Examples include words that create a sense of urgency, such as “act now“, or words that make false promises, such as “no risk” or “overnight success“.

It’s important to note that using a few of these words occasionally won’t necessarily trigger spam filters. But relying heavily on them, or using them in a misleading way, can significantly increase your chances of ending up in spam.

For example, using the word “free” in an email is generally acceptable. However, using “free” repeatedly with other terms such as “free bank account” or “free housing” can raise red flags and lead to spam filters.

Why should you avoid spam trigger words?

The primary reason is to ensure that your emails reach the inboxes of their intended recipients. Spam filters are constantly evolving, and they look for these red flags to identify and redirect spam messages.

Using trigger words can increase the chances of your email being flagged and sent to the spam folder, defeating the purpose of sending it in the first place.

Even if your email avoids spam filters, excessive use of trigger words can make your email appear unprofessional or untrustworthy.

For example, recipients who see words like “free miracle cure” or “urgent act now!!!” may be less likely to take your message seriously or even find it offensive.

What are spam filters and how do they work?

Spam filters are like bouncers for your inbox, constantly checking incoming email to see if it’s legitimate or not. They use a combination of techniques to catch spam before it reaches your precious inbox. Here’s a breakdown of how they work:

Types of spam filters

Header filters: These detectives examine the email’s header information, which includes the sender’s address, list of recipients, and routing details. They look for suspicious signs, such as a sender address that doesn’t match the domain name or a history of sending spam.
Content filters: These go through the body of the email and analyze the text for red flags. They look for common spam trigger words (such as “free” or “urgent”) and analyze the overall tone and style of the writing.
Blacklist filters: Imagine a naughty list of email addresses and domains. Blacklist filters check sender information against constantly updated databases of known spammers. If there’s a match, the email is flagged.
Authentication filters: These look for specific email authentication protocols such as DKIM and DMARC. These technologies help verify that the email is actually from the sender it claims to be, reducing the risk of spoofing.
