How do I sort replies by language?

  1. Export the replies as a CSV or .xlsx, or paste the cells with the header row first. It needs an Email column and a column of reply text.
  2. Press Detect the languages and read the counts.
  3. Download one file per language, the whole list with a language column, or the replies left untagged.
  4. Send each file to whoever replies in that language, and check the addresses before you write back.

Example

You enter
Example replies from seven addresses: six full sentences in English, German, French, Spanish, Italian and Dutch, and one that says Ok.
You get
Seven rows read: 6 replies tagged and 1 left untagged. English, German, French, Spanish, Italian and Dutch are found once each; Ok has too few words to tell.
Limits
Runs in your browser. Only common words in seven languages are counted.

How does it tell the language?

It lower-cases the reply, drops accents, and counts common function words such as the, und, pour, gracias, grazie, obrigado and bedankt. The language with the most matching words wins, as long as it has at least two and no other language ties it. Quoted history is removed first, so your own email does not count.

Why are some replies left untagged?

A reply such as Ok or Not interested has too few words to tell, and a reply that mixes two languages can tie. Those rows are left blank rather than guessed, and you can download them as the rest.

To find opt-outs in the same replies, use the unsubscribe request finder.

What is it useful for?

Lists that reach across countries get replies in several languages. Sorting them lets the right person answer, and shows which regions respond. See also email list by country for the same split by address.

Who uses this tool, and for what?

Cold email senders
Hand German and French replies to the teammates who speak them.
Sales ops
Route replies by language in a mixed-country campaign.
Agencies
Show a client which markets answer, with one file per language.

What can’t this tool tell you?

  • It covers seven languages; others are left untagged or tagged by mistake when they share words.
  • It counts common words, so very short or mixed replies are left blank.
  • It does not know the sender's country, only the words they wrote.
  • Check the rows if the language matters; it can be wrong.

Common questions

Which languages can it detect?
English, German, French, Spanish, Italian, Portuguese and Dutch.
Why is a short reply not tagged?
It needs at least two common words from one language, and none tied with another.
Does it handle replies with a quoted email below?
Yes. Quoted lines and anything under a line like On Monday ... wrote: are ignored.
Which column does it read?
A column whose header says reply, message, body, text, response or content, otherwise the column with the most text.
Does it translate the replies?
No. It only tags the language.
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
