From the google docs on importing:
• You can import 3,000 contacts at a time. • Non-ASCII or non-Latin characters may not be accepted. • Any information formatted as a group or distribution list won't transfer into your Gmail Contacts list. • Importing information that matches the email address of an existing entry will replace the information in your Contacts list with the most recently uploaded information. Looks like you have about 133 files to split and script into it :) On Aug 19, 2009, at 1:17 PM, Mahmoud Abdur-Rahman wrote:
This is already the approach I've followed and it worked. I created a contact (CSV) file and imported it into a gmail account. It was around 1700+e-mail addresses which correspond to one segment of the customers. I got the list and I copied them and started to omit the information I don't need. But when I tried to work with the second group in order it didn't work as there're 30,000+ e-mail addresses. I tried to split them into 2 groups, it didn't work. Simply the gmail and Yahoo! are not able to import them due to the large number. I didn't get your concern about the ethics and privacy. I didn't crawl those e-mails or buy them. They're our customers and we want to invite them to our page. They gave us their e-mail addresses so willingly and I guess we're not misusing them.
