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.

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.

Is there a limit to how many emails I can validate at once?

You can process large lists at once, though performance may vary depending on the size of your input list.

What does the quality check feature do?

It identifies common formatting errors, such as missing '@' symbols, invalid characters, or improperly structured domain names.

Can I export the results?

The results are displayed in text format, which you can easily copy and paste into your preferred spreadsheet or text editor.
