You must not: You actually should not email a resume cover letter without having a cv. Make sure you address the job application letter personally, keep away from sentences such as "To Whom it May Concern". Lexical, format and punctuation errors are forbidden in the job cover letter. Stick to the point, keep away from excessive conversations. As it feels excellent to own one generic letter for those work you are applying to, it is actually bad. It will always be advisable to do some researching and compose a unique letter for each and every firm that gives a position.
