Amazon SES e-mails ending in Yahoo & Hotmail Spam folders, even though SPF and SenderID and DKIM are set correctly

Hello all, I really get fustrated by this issue. My e-mails sendt from my app are ending in Yahoo & Hotmail Spam folders, but not in gmail (at least most of the time). I followed the AWS SES guide to add my domain, add DKIM, SPF, added custom from adress and did thee verification for that too. Everything is perfect. When I send emails to clients, specially yahoo & hotmail, they either bounce and the email gets added to my suppression list, or the email goes and land in spam. I thought I missed my config somewhere so I checked my config on tools like: https://www.mail-tester.com/ https://www.mailgenius.com/ Which all told me that my config is 10/10 I have this domain for more than 6 months. I just launched my app but all the users complain nor receiving the email on signup which is quite annoying. I really dont know what to do at this stage. I checked all the AWS guides for email authentication and they are done. but still...HELP
