Soft Bounce Rate Very High

User_4MTVT Posts: 1 Green Ribbon

How does Eloqua mark an email address that has soft bounced multiple times? How would you find these soft bounces?

Thank you


  • Hi User_4MTVT

    Thank you for reaching out to the community forum with your question.

    Oracle Eloqua converts a soft bounce to a hard bounce when Oracle Eloqua receives the soft bounce error 421 4.4.0 [internal] no MXs for this domain could be reached at this time 3 times within 12 months. After receiving this same error for the forth time, Oracle Eloqua assumes the email address is invalid, updates the contact's bounce status, and marks the email address as invalid. After that, Oracle Eloqua automatically excludes the contact from future email sends.

    More detail on bounces is available here.
