High Bounce Rate. Blocked by Spamhouse, but not listed in their blacklist.
Hi community!
For one of my recent email campaigns the bounce rate was over 3% which is absolutely unusual for this account. Most of the bounces were on comcast.net domain. In the bounce reason I have a lot of “blocked by Spamhaus”. So I checked the IP reputation on Spamhaus and it says “not listed”.
This specific bounce reason also happens for other domains, including hotmail.com.
How should I approach this?
Thank you!
