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.

No — sender reputation, authentication and engagement matter too. But clean content removes an easy reason to filter you.

A higher score means fewer issues under this checker’s content rules. It is not a probability of inbox placement or a guarantee that a provider will accept the message. Review the actual flags and test the full sending setup.
