Which English form is correct:
I have sent you an email or I have send you an email ?

2

When using the helping verb have, the correct form of the past tense of the verb to send is sent.

Expert Tip: If the action is complete, it is usually better to use the more direct form, I sent you an email.

I have send you an email

It's not correct. Don't use this phrase.

Verb Tense: Including the auxiliary verb have, tells us the action happened in the past, so the past tense of the main verb, sent, must be used.

Preferred Form

I have sent

This phrase is used for several reasons:

To indicate that something was sent at some non-specific point in the past.

To indicate the action is not fully completed

To confirm that an action was done.
