Follow Up or Follow-Up: The Correct Form Depends on Usage

Follow up and follow-up are both correct, but they do different jobs in a sentence. The verb is follow up, while follow-up is used as a noun or adjective.

The one-word form followup is generally not the standard choice in edited English.

If you are writing an email, report, article, or business message, this simple rule will keep you on the safe side:

Verb: follow up
Noun or adjective: follow-up

Quick Answer

Use follow up when it describes an action:

I will follow up tomorrow.
She followed up with the client.
Please follow up on the request.

Use follow-up when it acts as a noun or describes another noun:

We scheduled a follow-up.
I sent a follow-up email.
They arranged a follow-up meeting.

Followup as one word is generally not preferred in standard professional writing.

Follow Up as a Verb

Follow up is a phrasal verb. It means to take further action, contact someone again, or check on something that has already been discussed or started.

Examples:

I will follow up with you next week.
Please follow up on my application.
She followed up after the interview.
We need to follow up with the customer.
He called to follow up on the request.

Because it is a verb, follow up stays as two separate words.

Follow Up With

Use follow up with when you mean to contact or communicate with a person again.

I will follow up with the manager tomorrow.

She followed up with the client after the meeting.

Follow Up On

Use follow up on when you mean to check or take further action concerning a subject, issue, request, or task.

I need to follow up on your application.

We should follow up on this issue next week.

Follow-Up as a Noun

Follow-up is a noun when it refers to a later action, contact, response, or appointment.

Examples:

We scheduled a follow-up.
I sent a follow-up after the interview.
The doctor recommended a follow-up.
The manager requested a follow-up.
We had several follow-ups during the project.

Plural of Follow-Up

The plural is follow-ups.

The hyphen remains in the plural form:

The team made several follow-ups.
We had two follow-ups with the client.
Regular follow-ups helped keep the project moving.

Follow-Up as an Adjective

Follow-up can also describe another noun. In this use, the hyphen connects the words into a compound modifier.

Common examples include:

follow-up email
follow-up meeting
follow-up call
follow-up question
follow-up message
follow-up appointment
follow-up interview
follow-up report

For example:

I sent a follow-up email this morning.

Here, follow-up describes the type of email.

Follow-Up Meeting or Follow Up Meeting?

The standard form is follow-up meeting.

We scheduled a follow-up meeting for Friday.

Here, follow-up describes meeting, so the hyphen is appropriate.

But when the phrase is used as a verb, write it as two words:

We will follow up after the meeting.

Compare:

Form	Example
follow up	We will follow up tomorrow.
follow-up	We scheduled a follow-up.
follow-up meeting	We scheduled a follow-up meeting.

This distinction is based on the grammatical role of the phrase.

Does Follow-Up Email Have a Hyphen?

Yes. Follow-up email is the standard form when follow-up comes before email as a compound modifier.

I sent a follow-up email after our conversation.

However, do not add a hyphen when follow up is the verb:

I will follow up by email tomorrow.

The same pattern applies to phrases such as follow-up call, follow-up question, and follow-up appointment.

Is Followup One Word?

For standard professional English, it is best to avoid followup as one word.

Use:

follow up for the verb
follow-up for the noun
follow-up for the adjective

For example:

Correct: I will follow up tomorrow.

Correct: I sent a follow-up email.

Avoid: I will followup tomorrow.

Avoid: I sent a followup yesterday.

You may encounter followup in informal, technical, or system-generated text, but that does not make it the preferred form for careful writing.

Follow Up vs. Follow-Up vs. Followup

The easiest way to remember the difference is to look at what the phrase is doing.

Form	Function	Example
follow up	Verb	I will follow up tomorrow.
follow-up	Noun	We scheduled a follow-up.
follow-up	Adjective	I sent a follow-up email.
followup	One-word form	Generally avoid in professional writing.

A quick test can help: if you can put will, should, can, or to before it, you are probably using the verb follow up.

I will follow up.
We should follow up.
She needs to follow up.

If it names a thing or describes another noun, follow-up is usually the right choice.

Follow Up in Professional Emails

Follow up is perfectly natural in professional emails. The important thing is to use the correct form.

For example:

I wanted to follow up on my previous email.

I’m writing to follow up regarding the proposal.

I wanted to check in and see if there are any updates.

If you are naming the message itself, use follow-up:

I sent a follow-up email this morning.

You can also replace follow up with another phrase when it better matches your meaning.

Professional Alternatives to Follow Up

Depending on the situation, you could use:

check in
check on
reach out
confirm
revisit
contact again
get back to

For example:

I wanted to check in about the proposal.

This may sound softer than:

I wanted to follow up about the proposal.

The best alternative depends on what you want to communicate.

Common Mistakes

Using Followup as One Word

❌ I will followup with you tomorrow.

✅ I will follow up with you tomorrow.

Hyphenating the Verb

❌ I will follow-up tomorrow.

✅ I will follow up tomorrow.

The hyphen is not normally used when follow up functions as the verb.

Removing the Hyphen From a Compound Modifier

❌ We scheduled a follow up meeting.

✅ We scheduled a follow-up meeting.

When follow-up directly modifies another noun, the hyphen makes the compound easier to read.

Follow Up or Follow Through?

Follow up means to take more action or contact someone again.

I will follow up with the customer tomorrow.

Follow through means to finish something you promised to do.

She promised to finish the project and follow through.

So, use follow up for further contact or action. Use follow through when you mean to complete a plan or promise.

How to Use Follow Up Correctly

Here are some natural examples from everyday and professional writing:

Email

I wanted to follow up on my previous message.

Business

Our sales team will follow up with the client.

Healthcare

The doctor requested a follow-up appointment.

Education

The teacher will follow up with the parents.

Interviews

She sent a follow-up email after the interview.

Meetings

We arranged a follow-up meeting for next week.

Customer Service

I am writing to follow up on my support request.

These examples show the main pattern: follow up for the action and follow-up for the noun or modifier.
