How to trace ignored or rejected contacts ?
First of all, have your main list ready in an excel sheet. Once you imported the list on the platform, you can export it from the list management and view & edit. Then, just open it in excel.
Copy all the email addresses from the list that results from the platform and paste them under the contacts in your main list.
In excel, click on Conditional Formatting, select highlight cell values, duplicate values and finally format only unique or duplicate values, click OK.
The highlighted contacts are going to be in colour, the ones that were ignored or rejected won't be.
And there you have it! You can now know wish adresses weren't uploaded into the system and you can now test them yourself.
