Python - How to run a loop inside another loop with range?

Question

I don't know if my title really encompasses what I am trying to accomplish. I have a list of email addresses and I want to only email about 50 a day. So I have made the following scripts neither are working:

email_list = ['[email protected]','[email protected]','[email protected]','[email protected]','[email protected]']
for num in range(0, 2):
    for email in email_list:
        print(email)
    time.sleep(2)

email_list = ['[email protected]','[email protected]','[email protected]','[email protected]','[email protected]']
    for email in email_list:
        for num in range(0, 2):
            print(email)
        time.sleep(2)

So what I would like to do is run the script for 50 times, then wait for a specific period of time then run the next cycle.

What about

email_list =['[email protected]','[email protected]','[email protected]','[email protected]','[email protected]']
send = 0
for email in email_list:
    print(email)
    send += 1
    if send % 50 == 0:
        time.sleep(2)

This will wait 2 second every 50 mails printed

Looks like this works out of both of the answers I received. Why is it working with if send % 50 == 0?

the variable send counts how many mails were printed. send % 50 is the remainder of dividing send by 50, so it's 0 every 50 mails
