How can I avoid content-based spam triggers?

Avoiding content-based triggers starts with writing genuinely useful content rather than trying to game filters. Filters are designed to catch manipulation, so the best defense is authenticity.

Use clean, well-structured HTML with proper tags and no hidden elements. Maintain a healthy text-to-image ratio and always include a plain text version.

Limit links to those that are necessary and relevant. Use your own branded domains rather than URL shorteners. Ensure link text accurately describes the destination.

Avoid typographic tricks like excessive punctuation, all caps, and misleading characters. Write clear subject lines that accurately reflect the content.

Strong authentication (SPF, DKIM, DMARC) provides a foundation that makes content evaluation more forgiving. A trusted sender gets more latitude than an unknown one.

The best way to avoid suspicion is to have nothing to hide. Send content you would be proud to have inspected.
