In this enclosure (enclosed), please make an effort to locate (find) our proposal. Read it thoroughly and carefully (peruse) or else you know the consequences (!) (kindly). We expect you to get back (revert?) to us by next week.
In fact, they're dead giveaways that you've copied from somewhere - you didn't learn them in school.
So, do not misuse the following words in your writing:
- Find (redundant)
- Perusal (legalistic)
- Kindly (old-fashioned)
- Revert (does not mean reply)
Note: Revert means to return to a former habit, practice, belief, condition, state, topic, etc.
How about the word "enclose" vs "attach"? Strictly speaking, an email does not have "enclosure(s)" (unlike a letter, parcel, or package). Instead, an email can come with "attachment(s)". Therefore, "attach" is a better choice, but "enclose" is acceptable.
Here's an amended version of the above email:
I attach our proposal for your review and look forward to hearing from you by next week.
Take a moment to test yourself before continuing...
