Quick answer:
“Follow up” is the correct verb.
“Follow-up” (with a hyphen) is the correct noun or adjective.
“Followup” as one word is generally incorrect in standard English.
Many people search followup or follow up because both forms appear constantly especially in emails, messages, and business writing.
You’ll often see lines like “Just following up” or “This is a followup email”, which adds to the confusion.
The issue isn’t pronunciation. It’s grammar. English treats actions and things differently, and small spacing or hyphen changes affect correctness.
Since “follow up” is widely used in professional and online communication, writers want a clear rule they can trust.
This article explains the difference in simple terms, with real examples and practical advice, so you can use the correct form confidently every time.
Followup or Follow Up – Quick Answer
✔ Follow up → verb (an action)
✔ Follow-up → noun or adjective (a thing or description)
✘ Followup → incorrect in formal writing
Examples:
- I will follow up tomorrow. (verb)
- This is a follow-up email. (noun)
- We scheduled a follow-up call. (adjective)
If you’re describing an action, use two words.
If you’re naming something, use the hyphenated form.
The Origin of “Follow Up”

The phrase follow up comes from the verb follow, meaning to come after, combined with up, which adds the sense of completion or continuation.
As English evolved, this phrasal verb became common in both spoken and written language.
Over time, writers also needed a way to name the action itself, which led to the hyphenated form follow-up.
However, the closed compound “followup” never became standard. Major style guides and dictionaries still treat it as informal or incorrect in professional writing.
This history explains why the spacing and hyphen matter.
