I apply 'Send an email (V2)' and send emails to the people in the list ---> 2 times with the same template.
1st time: Send to 3 emails > Success and all 3 people in the list received emails.
2nd time: Send to around 1,000 emails > Success BUT no one received any emails.
I'm quite not sure that is the number of emails too much? How's the limitation for the number of emails? Or the issue was caused by any other reasons? How to solve this issue?
Thank you in advance for helping me.
