I can successfully send emails using the python sdk through my local machine but when I move the same code to aws lambda it times out(tried for 6 minutes max) and I do not get any error or email. Point to be noted, I used the same ET_Client object to get data from data extension and that worked fine in lambda.
I have referred this link: https://github.com/salesforce-marketingcloud/FuelSDK-Python/blob/master/objsamples/sample_triggeredsend.py
Also, I was able to send triggeredsends a day before and was trying to automate it and sent 200+ triggeredSends simultaneously. Is this a case of blacklisting or something else?
