I have an excel online file with a full list of 4236 users' email addresses. Now I want to send emails to those users from a shared mailbox. I created that list into a table format so that I can get the email addresses as dynamic values using "list rows present in a table" but I want to get/send only 30 emails per session and give 1 min delay and get/send next 31-60 serial emails again with 1 min delay and again 61-90 serial emails.
currently, I am using an easy but time-consuming method by creating multiple tables and

but I need help to create a dynamic flow that will only send email 30 emails after that with a 1 min delay.
