Hello @DanielT293 ,
Trial accounts can only do up to 100 sendouts during their trial period (e.g. 1 email to 100 contacts, 2 emails to 50 contacts, 5 emails to 20 contacts, etc.) To send to your contacts, you'll need to make a smaller list or reduce the size of your main list to 100 or less. Paid accounts have unlimited sendouts.
