Delay in routine while sending email - solution in Python program?

Question

Hello community, hello MSFT-team, I think the problem is already know as I read here: Why sending a mail using Azure email communication service is too slow? I fixed the issue now form me by modifying the sample code as following:

poller = client.begin_send(message)
#result = poller.result()

for the moment that works fine for me and users don't have to wait 10-20 sec. for a response. But I'm not sure if that is a good solution and what problems that might cause. Any ideas or suggestions for a better solution? Cheers Michael
