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.

In this sentence, aún and todavía are usually interchangeable:

• Aún no he enviado el correo
• Todavía no he enviado el correo

Both mean I haven’t sent the email yet.

Very generally:

• todavía is extremely common in everyday speech
• aún can sound a little more formal or written in some contexts

But both are perfectly normal.

Here aún has a written accent because it means still or yet.

Spanish also has aun without an accent, which often means even or including in certain contexts.

Examples:

• Aún no ha llegado = He/She still hasn’t arrived
• Aun los niños lo entienden = Even the children understand it

In modern usage, many learners just need to remember:

• aún = still / yet
• aun = often even

He is the first-person singular form of the auxiliary verb haber in the present tense.

So:

• he = I have
• has = you have (informal singular)
• ha = he/she has
• hemos = we have
• habéis = you all have (Spain)
• han = they have / you all have

In he enviado:

• he = auxiliary verb
• enviado = past participle

Together they make the present perfect: I have sent.

Important: this he is not the pronoun he in English.

Because after haber, the past participle does not agree with gender or number.

So with haber, you use the same form:

• He enviado
• He enviado la carta
• He enviado los documentos
• He enviado las fotos

It stays enviado every time.

Agreement can happen with adjectives or sometimes with participles used differently, but not in the normal perfect tense with haber.

Spanish often leaves out subject pronouns because the verb form already shows who the subject is.

• he enviado clearly means I have sent

So Aún no he enviado el correo is completely natural.

You could say:

• Yo aún no he enviado el correo

but yo is usually added only for emphasis, contrast, or clarity.

For example:

• Yo aún no he enviado el correo, pero ella sí. = I still haven’t sent the email, but she has.

Yes. Several word orders are natural:

• Aún no he enviado el correo
• Todavía no he enviado el correo
• No he enviado aún el correo
• No he enviado el correo todavía

These all mean roughly I haven’t sent the email yet.

The most neutral and common patterns are:

• Aún no + verb
• Todavía no + verb
• No + verb + todavía

All are useful to know.

In Spanish, no normally goes before the conjugated verb:

• No he enviado...
• No tengo...
• No quiero...

So in this sentence:

• Aún no he enviado el correo

the negative marker no comes before he.

This is standard Spanish word order.

Literally, correo can mean mail/post, but in modern context it often means email, especially when the meaning is obvious.

So:

• enviar el correo often means send the email
• correo electrónico is the full form for email

In everyday speech, people often shorten correo electrónico to just correo.

Depending on context, el correo could also mean the postal mail, but here most learners will understand it as the email.

Yes, absolutely.

• Aún no he enviado el correo electrónico

This is a little more explicit and can sound slightly more formal or precise.

In normal conversation, though, el correo is very common if everyone already knows you mean an email.

Yes, the h in Spanish is silent.

So he is pronounced roughly like eh.

A rough pronunciation of the whole sentence is:

• a-OON no ay en-vee-AH-doh el koh-RREH-oh

A few notes:

• aún has stress on the second syllable
• he sounds like eh
• enviado is usually pronounced with a clear i-a sequence
• correo has a rolled or tapped r sound depending on the speaker and position

It can mean both, and in many situations the English translations are interchangeable.

• I haven’t sent the email yet is often the most natural translation
• I still haven’t sent the email adds a little more sense of delay or frustration

Spanish aún no can cover both ideas depending on tone and context.

So if someone asks whether you have sent it, this sentence could simply be neutral. But if you say it with emphasis, it can also suggest it’s still not done.
