Bought 8 domains in last 5 days ( start warmup emails ) and 5 domains come on SEM Fresh blacklist and 1 domain that is from last year ( today come in spamhaus blacklist ) what i am doing wrong that is costing me domains )

Bought 2 domains checked and they both are in SEM FRESH and SEM URIRED Listing I didn't check it before buying so think they are already in that list and didn't make any mailboxes yet on them Bought 3 more domains all cleaned added it to reseller , make 6 maibloxes and guess what 2 of them started in that same listing ( SAM FRESH AND SAM URIRED ) What i am doing wrong Doesn't send a single email yet from them ( is this normal after buying a domain you get in these listing automatically ) What to do now change the mailbox provider make new mailboxes and then start the warmup or start the warmup with the mailboxes

- bougth 2 domains yesterday ( and forget to check its reputation before buying ) after buying i go to check and both domains that i bought comes on these lists ( SEM FRESH ) and (SEM URIRED) Now what to do ditch these domains or make mailboxes and start the warmup process - i have 1 year old 2 domains and they appear on these ( Suomispam Reputation ip15.197.162.184 was listed ) both domains showing same blacklist with this same ip what to do with these 2 ditch these or use another provider like i am using google , switch to microsoft for these domains - i have one more domain that i have warmup for like 1 month and do cold email for ilke 15 days and its comes on this list ( SURBL multi ) what to do with this domain i have deleted all the mailboxes from this domain from past 10 to 15 days and not doing anything - I have one more domain that i have bought with the upper domain both are on SURBL at that time ( i deleted all the mailboxes on both of those domains and now i checked it today and it is not on any blacklist what to do make new mailboxes and do the warmup and start the process or not ) PLz answer these 4 questions they are related to my 4 differnt domains and scenerios and different blacklists

How many mailboxes per domain ( i am doing currently 2 mailbox per domain ) How many warmup and cold emails i can send with 2 mailboxes ( 20 cold plus 10 warmup ) some are saying send 10 cold and 20 warmup So tell me what is the current working ratio?

Reason IP Address ( 15.197.162.184 was listed ) both domains showing same ip blacklist and both domains are on inbox insiders what to do stop sending emails or not And i think the reason my previous 2 domains blacklisted on spamhaus and these 2 ip got blacklisted i send like 1k emails without cleaning the list and got 5 to 7 bounces across mailboxes and my system got crash out Forget to clean
