What the warning means

  • Your bounce or complaint rate crossed HubSpot's threshold.
  • If it stays high, HubSpot can pause or suspend sending to protect their servers.
  • The fix is removing the contacts causing the bounces and complaints — not sending less.

HubSpot's term for this: email sending probation / suspension

HubSpot's published limits: hard bounce 5% · spam 0.1% · unsubscribe 3% (monthly)

This isn't a you problem. Every list rots.

Natural decay

People change jobs and abandon inboxes — addresses die quietly.

Bot signups

Bots submit real people's addresses through your forms; those people mark you as spam.

Old imports

Contacts from past tools or purchased lists that were never verified.

Proof

We got a bounce warning the week before our biggest send of the year. The free analysis showed us exactly which contacts to pull — we cleaned the list and shipped the campaign on schedule. No panic, no guesswork.
