Have you ever stopped while writing an email and wondered: should it be follow up or followup? You are not alone. Many people search this keyword because the spelling changes depending on how the word is used.
It can act as a verb, noun, or adjective, which creates confusion in business writing, emails, school assignments, and even social media posts.
Some people write “followup” as one word. Others use “follow-up” with a hyphen. Many use “follow up” as two separate words. So which one is right?
The answer depends on grammar and style. In most modern English writing, “follow up” is used as a verb, while “follow-up” is commonly used as a noun or adjective. “Followup” as one word is much less common and is often considered informal or incorrect in professional writing.
This guide explains the differences in simple language. You will learn the correct spelling, where each form is used, common mistakes to avoid, and which version works best for American, British, and global audiences.
Follow Up or Followup – Quick Answer
The correct form usually depends on how the word works in a sentence.
| Form | Usage | Example |
|---|---|---|
| Follow up | Verb | “I will follow up tomorrow.” |
| Follow-up | Noun/Adjective | “Send a follow-up email.” |
| Followup | Less common single-word form | “The doctor scheduled a followup.” |
Simple Rule
- Use follow up when talking about an action.
- Use follow-up when describing a thing or event.
- Avoid followup in formal writing unless a company or style guide accepts it.
Examples
- “Please follow up with the client.”
- “She sent a follow-up message.”
- “The meeting needed a follow-up.”
The Origin of Follow Up or Followup
The phrase “follow up” comes from the verb “follow.” It originally meant going after something or continuing an action. Over time, English speakers started using it in business, medicine, journalism, and daily communication.
In early English writing, “follow up” appeared mostly as two separate words because it described an action. Later, writers began adding a hyphen when the phrase became a noun or adjective.
For example:
- Verb: “We need to follow up.”
- Noun: “We scheduled a follow-up.”
The single-word form “followup” appeared later in informal and digital writing. Some industries, especially healthcare and software systems, use it as one word because databases and forms often remove spaces or hyphens.
Still, most dictionaries and professional editors prefer either:
- follow up (verb)
- follow-up (noun/adjective)
That is why spelling differences exist today.
British English vs American English Spelling
Both British English and American English mostly use the same spelling rules for this keyword. The main difference is style preference and punctuation habits.
American English
American English strongly prefers:
- follow up (verb)
- follow-up (noun/adjective)
Examples:
- “I will follow up next week.”
- “We received a follow-up call.”
British English
British English also uses the same forms, though some British publications use fewer hyphens in modern writing.
Examples:
- “The doctor asked for a follow up appointment.”
- “The company sent a follow-up letter.”
Comparison Table
| Usage Type | American English | British English |
|---|---|---|
| Verb | follow up | follow up |
| Noun | follow-up | follow-up or follow up |
| Adjective | follow-up meeting | follow-up meeting |
| Informal Single Word | Rare | Rare |
Key Difference
American writing keeps the hyphen more often. British writing sometimes removes it in casual text.
Which Spelling Should You Use?
The best spelling depends on your audience.
For American Audiences
Use:
- follow up for verbs
- follow-up for nouns and adjectives
This looks professional and matches major US style guides.
For British or Commonwealth Audiences
You can safely use:
- follow up
- follow-up
Both are widely understood. British readers may accept fewer hyphens in casual writing.
For Global Business Writing
The safest option is:
- “follow up” for actions
- “follow-up” for things
This avoids confusion and looks clean in emails, websites, and reports.
Best Professional Choice
If you want one simple rule for work writing:

Common Mistakes with Follow Up or Followup
Many writers mix the forms incorrectly. Here are the most common mistakes.

✅ “I sent a follow-up yesterday.”
Mistake 2: Using a Hyphen with Verbs
❌ “I will follow-up tomorrow.”
✅ “I will follow up tomorrow.”
Mistake 3: Forgetting the Hyphen for Nouns
