Using filters to exclude data

Learn how to apply filters in timetoreply to exclude irrelevant data and focus on the most important insights.

📊 Step-by-Step in Google Sheets

1. Open your spreadsheet

Let’s say your sender addresses are in Column B (starting from B2).

2. Create a new column next to it called Sender Type

3. Use this formula to classify the sender

Paste this formula into the first cell under Sender Type (e.g., C2):

excel

CopyEdit

=IF(REGEXMATCH(LOWER(B2), "noreply|no-reply|do-not-reply|notification|automated"), "System Notification",

 IF(REGEXMATCH(LOWER(B2), "linkedin"), "LinkedIn",

 IF(REGEXMATCH(LOWER(B2), "newsletter|digest|updates|info@|news@"), "Newsletter",

 IF(REGEXMATCH(LOWER(B2), "free|winner|claim|congratulations|promo"), "Spam",

 "Other"))))

4. Drag the formula down

Click the little square on the bottom-right of the cell and drag it down to apply it to all rows.

🔍 What this does:

  • LOWER(B2) makes everything lowercase (to avoid case mismatches).

  • REGEXMATCH looks for specific patterns (like "noreply" or "info@").

  • It then labels them as:
    • System Notification

    • LinkedIn

    • Newsletter

    • Spam

    • Or Other (likely a real person)

✅ Bonus Tips

  • Want to filter out all the skewed entries? Just filter the Sender Type column to exclude “Other”.
  • Want to create your own rules? Add more terms in the REGEXMATCH function like this: newsletter|digest|info@|weekly.
