Find spam in form submissions and sign-up lists

Flag spam, scams and junk entries in an export of sign-ups, comments or contact-form messages. Free, no sign-up.

CSV, Excel, Parquet or JSON. Up to 100 MB or 100,000 rows per file.

No file handy?

Always free. For your privacy, we don't keep anything: your file and results are deleted automatically within an hour.

Contact forms, waitlists and event registrations fill up with ads, scam links and keyboard-mash test entries. Cleaning the list by hand before importing it into your email tool or CRM is tedious, and simple keyword filters miss a lot.

Ask a yes/no question, such as whether the entry is spam, and every row gets a Yes or No with the probability behind it. Entries in the uncertain middle are flagged for you to check instead of being deleted automatically.

How to do it

  1. Export your form submissions or sign-up list as CSV or Excel.
  2. Select the name and message columns and choose "Yes or no". Describe what counts as spam for you.
  3. Preview, then download and filter on the Spam column before importing the clean rows elsewhere.

Example

Real results from the sample file (form submissions). The last row shows a case the model wasn't sure about, flagged for you to check:

Tips for better results

  • Spell out what Yes means: ads, scams, adult content, gibberish, test entries. The clearer the definition, the cleaner the result.
  • Phrase the question so Yes means spam. Questions like "Is this free of spam?" are easier to get wrong.
  • Raise the "needs review" cut-off if deleting a real person by mistake would be costly.

Questions

Will it delete anything?

No. It only adds columns to your file. You decide what to remove, for example by filtering on Spam = Yes.

Can it check email addresses?

It can read them, but it judges text, not whether a mailbox exists. Use an email verification service for deliverability checks.

What about borderline entries?

Rows where the probability is in the middle are marked "needs review", so you can look at those few instead of the whole list.
