This article provides estimated processing times for email address list files.
Verifying email addresses is a complex, time-intensive process whereby our systems interact with external mail systems.
Whilst we have control over our own systems, we have no control over remote mail systems and how they behave from a functionality and performance perspective.
Business email addresses tend to take longer to validate than consumer free email services.
There may also be occasions when our services are very busy however we do our best to try and ensure files are processed as quickly as possible.
For these reasons, it is not possible to provide a definitive time for completion of the verification process. However, we can provide some approximations based on our experience.
In the table below we have provided average processing times for various file sizes:
Amount of unique emails within list
|1,000||30 Minutes 3 Hours|
|2,500||1 Hour 4 Hours|
|5,000||2 Hours 5 Hours|
|10,000||3 Hours 6 Hours|
|25,000||4 Hours 7 Hours|
|50,000||5 Hours 8 Hours|
|75,000||6 Hours 9 Hours|
|100,000||7 Hours 10 Hours|
|200,000||8 Hours 11 Hours|
|250,000||9 Hours 12 Hours|
|300,000||10 Hours 13 Hours|
|400,000||11 Hours 14 Hours|
|500,000||12 Hours 15 Hours|
Please be aware these are approximate times only and are not guaranteed. Your file may take less or more time.
