Vou enviar o contato.

Portuguese often leaves out subject pronouns when the verb already makes the subject clear. Vou already tells you the subject is I, so both of these are correct:

• Vou enviar o contato.
• Eu vou enviar o contato.

Adding eu usually gives extra emphasis or contrast, like I will send it, not someone else.

It is the very common future construction ir + infinitive:

• vou = I go / I am going from the verb ir
• enviar = to send

Together, vou enviar means I’m going to send or I’ll send.

In everyday Brazilian Portuguese, this is one of the most common ways to talk about the future.

Yes. Enviarei is the simple future form of enviar.

So both are correct:

• Vou enviar o contato.
• Enviarei o contato.

The difference is mostly style:

• vou enviar = more common in everyday speech
• enviarei = more formal, more written, or more deliberate

In normal conversation in Brazil, vou enviar is usually the more natural choice.

Portuguese uses definite articles more often than English does. Here, o contato usually means a specific contact that both people can identify from context.

So o contato can sound more natural than bare contato in this kind of sentence.

English often says I’ll send contact info, but Portuguese frequently prefers something like Vou enviar o contato or Vou enviar o contato dele.

It depends on context. Contato can mean:

• contact information
• a person in your contacts
• a contact person / connection

So this sentence could refer to:

• someone’s phone number or details
• a saved contact card
• a person you should talk to

Very often in real life, o contato means the contact details.

No. If the listener already knows, Portuguese can leave that out.

But if you want to include it, you can say:

• Vou enviar o contato para você.
• Vou te enviar o contato.

Both are common in Brazil.
Also, pra você is a very common spoken version of para você.

Often, yes. Both can mean to send.

For example:

• Vou enviar o contato.
• Vou mandar o contato.

In casual Brazilian Portuguese, mandar is extremely common.
Enviar can sound a bit more neutral or slightly more formal, but both work well here.

A simple approximation is:

voh en-vee-AR u con-TA-tu

A few useful points:

• vou is one syllable
• enviar is stressed on the last syllable
• unstressed o often sounds like u in Brazilian Portuguese, so o contato sounds more like u contato
• contato is stressed on ta

In connected speech, it flows together very smoothly.

The standard written form is:

• Vou enviá-lo.

That is because contato is masculine, so it becomes -lo.

This is correct, but in everyday Brazilian Portuguese, speakers often avoid this kind of attached object pronoun in casual speech and simply repeat the noun or rephrase:

• Vou enviar o contato.
• Vou te enviar o contato.
• Vou mandar isso.

So vou enviá-lo is good to know, but it can sound more formal or careful than everyday speech.

The article tells you: o contato.

That means contato is masculine. If it were feminine, you would see a instead of o.

So:

• o contato = masculine
• a would mark a feminine noun

Yes. In many contexts, vou enviar can match both English ideas.

It can sound like:

• a planned future action: I’m going to send
• a promise or immediate decision: I’ll send

Portuguese often lets context do the work instead of making a big grammatical distinction between those two English versions.
