We are an ESP provider from Czech Republic, Europe. Our clients are regular Czech companies with their own client database. Since yesterday, we have a problem with our domains used in emails for online version, logout link and tracking the links. We are receiving a bad score because of these domain names.
The score is, e.g.:
RAZOR2_CF_RANGE_51_100 = 0.365
RAZOR2_CF_RANGE_E8_51_100 = 2.43
RAZOR2_CHECK = 1.729
We found out that one of our client probably sent a campaign on bought DB (100.000 addresses), so we blocked him, but now we need to solve this issue.
To buy a new domains is a solution, but not long-term solution. Do you have any idea how to solve it?
Would it help that every user of our system would have (for these links in email) a subdomain like username.redirectdomain.com Or another solution—registering to some whitelist?
There should be a solution when you from 95% do not send spam and you don't want to replace your domains every week. HW and IP addresses we have solved well, we have problem with this penalization in email body—especially for domain names used for tracking the links (official links are replaced with ours).
