Send vs. Sent: What’s the Difference and When Should You Use Each?

Quick Answer: Send is the base form of the verb, while sent is the past tense and past participle of send.

Use send for present actions, instructions, and after helping verbs such as will, can, and did. Use sent for an action that happened in the past or after have, has, or had.

The confusion is common because send and sent come from the same verb, but they do not work in the same grammatical situations. The key is to look at the tense and the helping verb around the word.

Send vs. Sent: The Basic Difference

The easiest way to remember the difference is:

Send = base form and present form
Sent = past tense and past participle

Word	Grammatical form	Example
send	Base form / present	I send emails every morning.
sent	Past tense	I sent the email yesterday.
sent	Past participle	I have sent the email.

So, send usually refers to an action in the present, a repeated action, a future action with a helping verb, or an instruction. Sent refers to a completed past action or appears with perfect tenses.

When to Use Send

Use send when the verb is in its base form. This happens in several common situations.

1. For present or repeated actions

Use send when talking about something that happens regularly or generally.

I send invoices every Friday.
We send customers a confirmation email.
They send messages through the app.
I usually send my reports before noon.

For third-person singular subjects such as he, she, and it, use sends, not send.

She sends me a message every morning.
He sends the documents by email.

2. After “will,” “can,” “should,” and other modal verbs

After a modal or similar helping verb, use the base form send.

I will send the file tonight.
Can you send me the address?
You should send a reply.
We might send another email tomorrow.

Not:

I will sent the file. ❌
Can you sent me the address? ❌

The helping verb already establishes the grammatical structure, so the base form send follows it.

3. For instructions and requests

Use send when telling or asking someone to send something.

Send me the details.
Please send the document.
Send the payment confirmation when you receive it.
Can you send me the link?

When to Use Sent

Use sent when talking about an action that happened in the past.

1. For a completed past action

I sent the email yesterday.
She sent me a message last night.
We sent the documents two hours ago.
He sent the package on Monday.

Here, the action has already happened, so sent is the correct past-tense form.

2. After have, has, or had

Sent is also the past participle of send, so it is used with have, has, and had.

I have sent the email.
She has sent the documents.
They had sent the package before noon.

Compare these:

I sent the email yesterday. → simple past
I have sent the email. → present perfect
I had sent the email before he called. → past perfect

Send vs. Sent in Questions

One of the most common mistakes occurs in questions with did.

Correct:

Did you send the email?

Incorrect:

Did you sent the email? ❌

Why? Because did already marks the sentence as past tense. The main verb must return to its base form, send.

The same rule applies to other verbs:

Did you send it?
Did she send the message?
Did they send the documents?

Not:

Did you sent it? ❌
Did she sent the message? ❌

This is an especially useful rule to remember when writing emails or text messages.

“I Send” vs. “I Sent”

The difference depends on when the action happens.

I send the report every Monday.
This describes a regular action.

I sent the report yesterday.
This describes a completed action in the past.

I will send the report tomorrow.
This describes a future action.

Notice how the time changes the correct verb form:

Every Monday → send
Yesterday → sent
Tomorrow → send after will

“Have You Sent” vs. “Have You Send”

The correct phrase is:

Have you sent the email? ✅

Not:

Have you send the email? ❌

After have or has in the present perfect, use the past participle. Since sent is the past participle of send, it is required here.

Examples:

Have you sent the invitation?
Has she sent the file?
Have they sent the payment?

“Send Me” vs. “Sent Me”

These phrases have different meanings because they use different forms of the verb.

Send me the file.
This is a request or instruction.

She sent me the file.
This tells us that she already sent it.

Compare:

Send me the address. → Please send it.
She sent me the address. → She already sent it.
I will send you the address. → I plan to send it.
I have sent you the address. → It has already been sent.

Common Mistakes With Send and Sent

Here are some mistakes English learners frequently make:

❌ I sent it tomorrow.
✅ I will send it tomorrow.

❌ Did you sent the email?
✅ Did you send the email?

❌ Can you sent me the link?
✅ Can you send me the link?

❌ I have send the document.
✅ I have sent the document.

❌ She send me a message yesterday.
✅ She sent me a message yesterday.

The easiest way to avoid these mistakes is to check the helping verb and the time of the action before choosing send or sent.

A Simple Way to Remember Send vs. Sent

Think of send as the basic form and sent as the form used for completed actions.

Send → present/base form
Sent → past/past participle

For example:

I send emails every day.
I sent an email yesterday.
I will send another email tomorrow.
I have sent the email already.

If you remember these four patterns, most everyday uses become easy to distinguish.
