Examples

1. Cleaning a Marketing Lead List

Marketing Specialist
Background
A marketing team has a list of 500 leads exported from a legacy system that contains many typos and formatting errors.
Problem
The team needs to remove invalid entries before importing the list into their email automation software to avoid high bounce rates.
How to Use
Paste the list into the tool, select 'Comma' as the delimiter, and ensure 'Check Email Quality' is enabled.
Example Config
delimiter: comma, checkQuality: true, showSummary: true
Outcome
The tool identifies and flags malformed emails, allowing the user to quickly filter out invalid addresses and proceed with a clean list.

2. Standardizing CRM Data

Database Administrator
Background
An administrator is merging two different customer databases and suspects that many email addresses are incorrectly formatted.
Problem
Manually checking thousands of entries for syntax errors is inefficient and prone to human error.
How to Use
Upload the combined list using 'New Line' as the delimiter and run the validation to generate a summary report.
Example Config
delimiter: newline, checkQuality: true, showSummary: true
Outcome
The administrator receives a clear report of valid versus invalid emails, enabling a quick cleanup of the merged database.
