About spam scoring

Why good emails still get filtered

Spammy phrases, excessive caps and exclamation marks are classic filter triggers.

Too many links

Several links — especially shorteners — raise spam scores. Keep it to one or two.

Missing opt-out

No unsubscribe path signals bulk spam to filters and breaks compliance.
