Is there a limit concerning the number of contacts imported?

Hello !

How many contacts could I import for a broadcast mailing. I've 300 000 emails for my advertising action. Can I do it in one shot ? or may I have to send step by step (10 000 by 10 000 for example) ?

Thanks a lot

I have heard of users importing up to 100,000 recipients. I guess you could import 300,000 as well but it is always better to use smaller lists.
