What Each Metric Means

A clear explanation of every analytics metric so you know exactly what changed in your lead list and why.

CSVgo analytics show eight core metrics that summarize how your lead list was processed.

Each metric represents a specific step in the cleanup and verification workflow. Together, they explain how raw data turns into campaign-ready output.

---

1. Initial Rows

The total number of rows in the uploaded file before any processing.

Includes:

• Duplicate rows

• Rows without emails

• Unused or junk columns

This is the raw input size.

---

2. After Deduplication

The number of rows remaining after automatic deduplication.

CSVgo removes:

• Duplicate email addresses

• Exact duplicate rows

This prevents double sending and wasted verification credits.

---

3. Duplicates Removed

The number of rows eliminated because they were duplicates.

This typically happens when:

• Lists are merged from multiple sources

• Data is exported multiple times from the same tool

Removing duplicates improves deliverability and accuracy.

---

4. No Email Rows

Rows where no email address could be detected.

These rows are not discarded. They are preserved and exported separately for:

• Waterfall enrichment

• LinkedIn campaigns

• Call-based outreach

---

5. Email Rows

The number of rows that contained an email address and entered verification.

This is the base number used for all email-related metrics.

---

6. Valid Emails

Emails classified as deliverable after verification and catch-all analysis.

This includes:

• Standard valid mailboxes

• Catch-all emails confirmed as deliverable

These emails are safe to send based on recipient-side signals.

---

7. Invalid Emails

Emails classified as undeliverable.

Common reasons:

• Non-existent mailboxes

• Invalid or inactive domains

• Hard failure signals

These should not be used for outbound sending.

---

8. Deliverable Rate

The percentage of email rows marked as deliverable.

This metric reflects:

• List quality

• Data source quality

• The impact of catch-all verification

It is not an inbox placement guarantee, but a strong readiness indicator.

---

How to Use These Metrics Together

• Compare Initial Rows vs After Deduplication to spot list inflation

• Compare Email Rows vs Valid Emails to assess data source quality

• Watch Deliverable Rate across different providers or segments

• Use No Email Rows to unlock additional outreach channels

Key Takeaway

These eight metrics are designed to:

• Be transparent

• Be comparable across files

• Help you make faster campaign decisions

CSVgo analytics focus on what you can actually use, not vanity numbers.
