We’ve completed our primary analysis! Now, let’s test the accuracy of email verification services.
2 - Accuracy analysis
We rank vendors by their email verification accuracy. Vendors with the higher verification accuracy are listed on the top.
How do we check their email verification accuracy?
We invest huge time in conducting an in-depth audit of their services. We ensure full perfection while measuring their verification accuracy, turnaround time, customer support and detection capabilities. We’ve shown our process of calculating verification accuracy down there:
Step 1
At listcleaningadvice.com, we prepare a "master email list" consisting of various email addresses, including valid emails, invalid emails, catch-all emails, spam traps, role-based Emails, and disposable emails. Before conducting their audit, we never disclose this secret email list to the vendors.
Step 2
We upload "Master Email List" to the vendor's website for verification.
Step 3
After obtaining the results, they are compared against our "Master email list" and perfectly figure out the vendor's accuracy.
Step 4
This Audit is performed every 3 months with the new data.
This method of comparison is very accurate, and very easy to understand. Let’s have a look at it!
Let's get you to the most accurate, and very easy to understand table showing the full comparison of the best Email Verifier websites!

3 - Turnaround time Assessment
Turnaround time is the time taken by the vendor to verify email addresses. We measure the accurate turn around time for processing 10,000 email addresses. Won’t you like to know how we calculate the turnaround time?
How do we calculate turnaround time?
Step 1
We upload a list of 200 email addresses, consisting of Gmail, Yahoo, Hotmail, Business, and Personal email addresses to the vendor's website.
Step 2
We note the exact time a vendor takes to process these 200 email addresses.
Step 3
We further compare our obtained turnaround time to what that vendor claimed.
In many cases, vendors do not disclose turnaround time on their websites. In such cases, we consider the industry's average time and compare it with the actual time taken by that vendor to process 10k email addresses.
| Turnaround time - If claimed by Vendor | Turnaround time - If not claimed by Vendor |

5 - Security Assessment
The security of the data is critical! An email verification provider must abide by data security and privacy laws. For security analysis, we consider data privacy and security policies, GDPR compliance, TOS, etc. We also take a physical address and other relevant information from the vendors' accounts.
" Data privacy and security - Maintaining data privacy has gone tough now. Hence, it's essential to know whether the email verification service provider ensures data privacy and security. Therefore, we profoundly analyze the data privacy and security checks deployed by email verifiers, which helps you select a value from the worthless.
" GDPR compliance - GDPR is now a compulsion for processing large-scale data, and under the GDPR law, it is necessary to hire a Data protection officer. Every email verification service processes large-scale data of specialized categories that makes it mandatory for the email verification vendor to be GDPR compliant. You can trust this quality benchmark! We carefully research and record all the GDPR information listed by the email service providers because safeguarding our readers is our priority.
6 - Other factors
Besides accuracy and compliance, we consider some other relevant factors (deeper ones) while selecting the best email verification service. That adds an extra layer to the perfection of our ultimate listing system.
Ease of use
While rating the vendor based on ease of use, we consider features like:
- Dashboard functionalities.
- Customer Support.

Features
While buying services from any email verification company, it is necessary to be knowledgeable about some productive features such as:
- File formats accepted for uploading the list.
- File formats available for downloading the clean list.
- Integrations option available
On the basis of three major features we mentioned above, we rate the vendor in the following manner:
Free trials
- If any email verifier website isn’t facilitating free trials and permitting you to take a tour of their services, then we don’t recommend it, as it’s a pure gamble. Considering free trials, we rate on the basis of following points:
- The Volume of free credits available. I.e. 50, 100, 500 etc.
- Time - period of free credits available. I.e. one-time, daily, monthly etc.
- Whether or not credit card details are required for availing free credits.
Pricing models
- We compare different pricing models like pay-as-you-go, prepaid credits, monthly and annual plans to extract the transparency of the pricing models.
While giving star ratings on the basis of the price, we equally consider accuracy as the deciding factor, and after evaluating both factors perfectly, we list only those email verifier companies, which give true value for your money.
