Spam is now such a huge problem that large companies, Internet Service Providers (ISPs) and mail services have put complex spam filters in place. Understandably, they had no choice - their customers were being flooded with unmanageable levels of spam. Unfortunately, some of these filters are overly sensitive and block a lot of legitimate emails ("false-positives"). It's a problem faced by all online businesses and newsletter publishers. An ISP or mail service can delete any legitimate email that you send to your client or subscriber.
Some ISPs don't allow to whitelist email that their own customers specifically want but can't get, even at the specific request of customers. (A "whitelist" is a list of addresses that bypass filtering algorithms.) Many ISPs and mail services refuse to give you an explanation as to why your mail is being filtered. They block, but they don't answer "why" and don't take responsibility for those actions.
