Learn English – “it didn’t sent the messages”

In English, there are two rules for how to state the negative of a verb.

1. "Not" comes after the verb.

   Correct: "I am not at home."

   Incorrect: "I not am at home."

2. Except for a few cases, you must rephrase to use the auxiliary verb "do".

   Correct: "She does not eat meat." (from "She eats meat" -> "She does eat meat")

   Incorrect: "She eats not meat."

"She not enjoyed it" is wrong on both of these rules. "She did not enjoy it" (shortened to "She didn't enjoy it") is correct.

Both sentences are technically correct.

Which one you use largely comes down to how long ago you sent him the gift - if it was relatively recently, I'd use #1, if it was a while ago, #2.
