EDU email filter: find .edu and .ac.uk addresses in a list
In short: Upload a list with an Email column. Addresses on .edu, edu.xx, ac.xx and k12.xx.us domains are tagged by ending, and you download the academic rows, the rest, or the whole list with two new columns. Limit: It reads the end of the domain; it does not know which institutions exist.
Upload the list and the tool reads the domain of every address. It tags .edu, edu.au-style endings, ac.uk-style endings and US k12.xx.us school domains, then lets you download the academic rows, the rest, or the whole list with a group column. It reads the shape of the domain, so a school on a .org or .com is not found.
Price: this tool is free. Checking a whole email list is from $9/mo, and the first 100 checks are free with Google, no card. Check your list free nowSee pricing

How do I filter .edu emails from a list?
- Upload the .xlsx or CSV, or paste the cells with the header row first. It needs an Email column.
- Read the counts and the table of domain endings found.
- Download the academic addresses, the list without them, or the whole list with academic_group and academic_note columns added.
- Check the rows you keep before you send.
Example
- You enter
- Example list of six addresses: students.example.edu, cs.example.ac.uk, example.edu.au, district.k12.ca.us, example.com and example.org.
- You get
- Six rows read: 4 academic addresses and 2 others. One each is found on .edu, ac.uk, edu.au and a k12.ca.us school domain; example.com and example.org are not found.
- Limits
- Runs in your browser and reads the domain text only.
Which domains does it count as academic?
Four shapes. A domain ending in .edu. A domain ending in edu and a two-letter country ending, such as edu.au. A domain with ac as the second-level label under a country ending, such as ac.uk or ac.jp. And US school domains in the form k12, a state and .us. Subdomains count, so cs.example.ac.uk is read the same as example.ac.uk.
Why filter academic addresses out, or keep only them?
Students and alumni change or lose their mailbox when they leave, so an old academic list decays quickly. Sellers of student tools want only these rows, and sellers of business software often want none of them. Splitting first lets you send each group its own message and verify each group separately.
For consumer providers such as Gmail and Yahoo, use the free vs business email filter. To drop a named domain, use remove emails by domain.
What does it not find?
A university that uses a normal commercial domain (a .com, .org or .de name) looks like any other company, and so does a college in a country that does not use edu or ac endings. The tool does not look anything up; it reads the text after the @ only.
Who uses this tool, and for what?
- Cold email senders
- Keep academic rows out of a B2B list, or pull them into their own campaign.
- Sales ops
- Tag education leads in a mixed export before routing them.
- List builders
- Separate alumni and student rows that decay faster than staff rows.
What can’t this tool tell you?
- It reads the end of the domain; it does not know which institutions exist.
- Schools on .com, .org or other ordinary domains are not found.
- An academic ending says nothing about whether the mailbox still works.
- Only the endings listed on the page are read; other country conventions are not.
Common questions
- Does it find .edu.au and .ac.uk addresses?
- Yes. Any edu or ac second-level label under a two-letter country ending is found, along with plain .edu.
- Does it find school district addresses?
- US school domains in the k12.xx.us form are found. Districts on other domains are not.
- Does a .edu address mean a student?
- No. Staff, faculty, alumni and departments all use the same endings.
- Can I keep the academic rows and drop the rest?
- Yes. Download the academic addresses file for just those rows.
- Does it check that the mailbox exists?
- No. It reads the domain text only. Use the check button to verify the addresses.
- Is my list uploaded anywhere?
- No. It is read in your browser.
A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
- Upload the cleaned file as it is: CSVs up to 100,000 rows
- A real SMTP mailbox check on every row, with catch-all detection
