# Summary Dealers using CRM/ILM tools often struggle with poor email deliverability because these platforms typically send from IP addresses with poor reputation scores, causing emails to be flagged as spam by ISPs. The thread's key recommendation is to separate bulk marketing emails onto a different IP address than one-to-one customer communications, and to use dedicated third-party email services (like OnStation, BullsEye, or Dealersocket) rather than relying on in-house CRM email features. Contributors also provide practical tools for checking IP blacklist status (MXToolbox, SendScore.org) and emphasize compliance with CAN-SPAM requirements as essential for maintaining sender reputation.
