Why Are My Results Not in the Same Order as Uploaded?
Some email addresses take longer to validate than others. The most straightforward email address to verify will appear earlier in your results list, while more complex addresses will appear later. For this reason, your results will appear in a different order than in your original uploaded file.
ZeroBounce uses a multi-threaded email validation process to verify various complex email addresses as quickly as possible. Major ESP domains such as Yahoo, Gmail, and Hotmail validate quickly, while smaller company domains generally require further testing.
Can my results data be kept in order?
Creating a numbered column in your original spreadsheet is recommended if the order of the emails in your results is vital. This numbered column is associated with the email address, similar to the owner's name or IP address.
When you upload your file for email verification, we preserve that column and include it in your results file. You can then use that column to quickly re-sort your results.
What impacts email validationⓘ speeds for results?
ZeroBounce can validate emails quickly, verifying roughly 100,000 mixed email addresses in just 45 minutes. However, some addresses will return a result more rapidly than others.
The following factors can impact how quickly you obtain email verification results:
- The complexity of the email address (unique characters, length, customization)
- The email domain (major freemail domains are faster than smaller domains)
- Spam prevention tactics such as greylisting
- Email server configuration
What can I do to speed up email verification?
To expedite the email verification process, it's recommended to separate your email list by domain type. This is because it's much easier and quicker to verify addresses that use major freemail domains, such as Google or Yahoo.
By separating your freemail domains from less common ones, you can upload separate files for faster validation. You can then upload a dedicated list of more complex domains, which generally require additional testing.
Ultimately, the additional time taken on more complex domains allows you to obtain an accurate result. Not all company domains require complicated verification steps. The duration it takes to verify these addresses depends upon the nature of the email address and the specific domain configuration.
