There are many privacy coins out there that will protect your anonymity like Monaco, ZCash, Dash, PIVX, Verge. One way is to use Ring Signatures:

Ring Signatures are a type digital signature in which a group of signers is brought together to sign a transaction forming a ring. This is similar to a joint bank account but with the actual signer being unknown.

The actual sender generates a one-time spend key and the recipient is the only party that can detect and spend the funds based on that key. Since all outputs are unlinkable, the privacy of the recipient is ensured.
