Common Spam Trigger Words on Outbound Servers

Common Words That Trigger Spam Filters on BigRock Outbound Servers

Email service providers use automated spam-filtering systems to protect users from unwanted or malicious emails. One of the most common reasons emails are flagged as spam is the use of certain words or phrases that are frequently associated with unsolicited or deceptive messages. These are commonly referred to as spam trigger words.

Spam filtering algorithms are continuously updated, and no single list of spam words is permanent or exhaustive. However, excessive use or repetition of commonly flagged terms—especially in email subject lines or promotional content—can significantly increase the likelihood of messages being delivered to spam or junk folders.

This article highlights 100 commonly identified spam words and phrases that may trigger spam filters on BigRock outbound servers.

Important Notes

• These words are not strictly forbidden.

• Using multiple trigger words or repeating them excessively can impact email deliverability.

• If you experience inbox placement issues, review your email content and minimize the use of these terms.
