  • Voluntary listing
  • Upon request

Our team works to add new vendors on regular basis, vendors are either listed upon request or through the voluntary listing.

Step 1

We continuously search for reputed vendors in email verification business.

Performance Analysis

2 - Performance Analysis - Prime factors

After the preliminary listing of the vendor, an in-depth audit of their services is conducted. During the audit process their email verification accuracy, turnaround time, customer support and detection capabilities are measured.


Finding Accuracy of their Email Verification Results - Email verification accuracy is the most important factor while selecting a provider. Accuracy is measured by different multiple validation capabilities of the vendor. Here is how we calculate verification accuracy.

Step 1

At BulkEmailVerification we have a master email list which consists of various type of email addresses viz. Valid emails, Invalid emails, Catchall emails, Spamtrap emails, Role-based emails, and Disposable emails.

Step 2

The master list is uploaded to the vendor's website for verification.

Step 3

Once the results are obtained, they are compared with our master email list and vendor's accuracy is calculated.

Below is the example of comparison.
Example of Accuracy analysis
LCA - Email List BulkEmailVerification Findings Vendor Findings Vendor's Accuracy (%)
Valid emails 875 870 99.43 %
Invalid emails 75 60 80.00 %

3 - Turnaround time Assessment

Turnaround time is the time taken by the vendor to verify emails addresses. At LCA, turn around time is calculated for processing 10,000 email address.

How do we calculate turnaround time?

Step 1

A list of 10,000 email addresses, which consists of Gmail, Yahoo, Hotmail, Business and Personal email addresses is uploaded to the vendor's website.

Step 2

Time taken by vendors to process these 10k email addresses is noted.

Step 3

This turnaround time is compared against other vendor’s turn around time.

In many cases, vendors do not disclose turnaround time on their website. In such cases, we consider industry average time and that is compared with the actual time taken by that vendor.
