They do that to get past spam filters.
Never open those since it can be a virus.
Occasionally I get an email that contains normal words, often in paragraph length, that are in nonsensical order and completely out of context of the rest of the email. For example: The mummer with the broken head, who had become mysteriously one of the party, answered.
Sometimes, the text is just gobbledy ****. For example: The red horse flew the judge with a picnic basket.
Any ideas as to what this is or what is going on?
