How do excessive punctuation or emojis impact filters?

Excessive punctuation and emoji overuse can contribute to spam scores, though moderate use is generally safe. The key word is excessive.

Multiple exclamation marks !!! are a classic spam indicator. Heuristic filters specifically look for this pattern. Strings of question marks or other repeated punctuation trigger similar rules.

Emojis are more nuanced. A few relevant emojis in marketing email are common and accepted. Dozens of emojis crammed into a subject line resemble spam tactics and may add points. Some corporate filters block emoji-heavy content by policy.

Context matters. An email from a trusted sender with good authentication can include more punctuation and emojis than one from an unknown sender. But restraint is still advisable.

Enthusiasm is welcome; hysteria is suspicious. Express excitement without setting off alarm bells.
