Hello @RebaG21 ,
It looks like you already spoke with chat support, and they were able to assist you. For the sake of visibility, I also wanted to post here that the trial system only allows up to 100 sendouts. So if you send 1 email to 100 contacts, 3 emails to 33 contacts, 4 emails to 25 contacts, etc. you won't be able to send more until you upgrade to a paid plan. On paid plans, there are no restrictions on the numbers of emails you can send to the contacts you have (with respect to anti-spam etiquette).
