Hi. if they get your mail you will always be sent a response, first you get an automated reply, then a ticket number. Double check your spam filter in case it's been caught there.
Are all your titles different? Were they within ebids agreed title length or could they have been truncated?
Have you double checked the .txt or .tsv file you saved to upload to make sure the formatting is ok? I'm sure ebid will sort this out with you once they get your email. Meanwhile can i recommend you take a look at the USA bulk lister on
