Symptoms

Marketing or sales emails sent from HubSpot land in spam, quarantine, or show as delivered but nobody opens them.

Why it happens

• Sending domain not authenticated with DKIM
• SPF not including HubSpot, no DMARC record
• Emailing unengaged or purchased contacts
• Weak consent or no double opt-in
• High frequency, poor sender reputation
• Gmail and Yahoo bulk-sender rules (authentication, one-click unsubscribe, low spam rate)
