Questions & Answers about Aún no he enviado el correo.
He enviado is the present perfect: I have sent.
In Spain, the present perfect is very commonly used for actions that are connected to the present moment, especially with ideas like already, yet, today, this week, or so far.
So Aún no he enviado el correo means I still haven’t sent the email / I haven’t sent the email yet.
By contrast, envié is the preterite: I sent. That usually sounds more like a completed past action with less connection to the present.
In many parts of Latin America, people often use the preterite where Spain would prefer the present perfect.
Aún no means not yet or still not.
So:
- Aún no he enviado el correo = I haven’t sent the email yet
- Literally, it is something like Still not have I sent the email
It expresses that the action has not happened up to now, but it may still happen later.
A very common alternative is todavía no:
- Todavía no he enviado el correo
This means essentially the same thing.
