Same error message for an ISP
Why do I always get the same error message for a particular ISP?
If you always get the same error message for an ISP, your email or IP may have been detected as faulty by the ISP. Carry out the following recommendations:
- Check whether you receive a large percentage of failures linked to inexistent email addresses (User unknown failures).
- Update your subscription forms to detect any errors in the domain names entered (for example: gmaul.com or yaho.com).
- If you notice errors stating that your messages are declared as spam, or that your messages are constantly blocked, try excluding the recipients that have not opened or clicked in one of your messages in the last 12 months from the target.
If the problem persists, contact the commercial or deliverability services, Adobe Customer Care.
Denylist versus quarantine
-
What is the difference between a email address on denylist and a quarantined email address?
-
The status Denylisted is a result of a feedback loop (when a person reports a message as spam).
-
The status Quarantined is a result of a soft or hard bounce.
