Nah not for the big providers. The biggest problem is not having RUA for DMARC set up at all, set to None for the action or having an email in the RUA that will give a bounce message back to a sender (or not having DMARC at all in your DNS). The safe thing to do is set up SPF, DKIM and DMARC (correctly).

You cant always control getting into a spam box from time to time if someone in your IPs /24 makes it onto popular spam databases but that’s very temporary but it is also very possible someone in your /24 is always on the lists. You can check yourself and there are both scripts and sites that will check most of the popular ones for you.

/24 is a very popular CIDR to use for stuff like spam filtering or internet facing IPS.
