Spam filters are particularly sensitive to certain types of content. Here are some examples:
Excessive use of promotional language: Words like "Free," "Buy now," and "Discount" can raise red flags. All-caps text: Using all caps can come across as shouting and is often associated with spam. Too many exclamation marks: Overuse of punctuation can also trigger spam filters. Poor formatting: Emails with inconsistent fonts, colors, and sizes appear unprofessional and are often flagged. Untrusted links: Including links from questionable domains can harm your email’s credibility.
