What is Waiting period to send emails again after being marked as spam .

If you sent an email to someone who marked it as SPAM, why would you want to send it again to the same person? No amount of waiting would likely make them think it isn't SPAM the next time they get it.

Your best bet to keep your complaint rate down - is to not send e-mail that people complain about, and if they do complain about it, respect your recipient's wishes and do not send them the same or similar messages again.

As far as SES is concerned, if you do not have the account level suppression lists turned on (https://docs.aws.amazon.com/ses/latest/dg/sending-email-suppression-list.html), or you have a configuration-set suppression setup to override any account level suppression lists, then you can resend the message any time you want - but of course - you will likely get another complaint if you just resend the e-mail.

If your question is about what complaint rate is acceptable for AWS to not suspend your sending privileges, such that you can send unwanted messages again while remaining under the rate that you would get suspended for, I would contend that this is not a great strategy to follow.
