Our Adobe campaign classic installation is an on-premise. Whenever an email delivery is sent out with population more than 10k, the email delivery get speread across few days (there is no multi-wave setup). We have checked the send log history - if the send start at 9:01 am, then first few hundred email goes out and then few fails (due to soft/hard bounce) and then no email gets delivered for 1 hour. And it resumes sending again after an hour (10:01 am) and the same thing. As a result, the 10k gets speread across multiple days and delivered across different time. Some may be even in the middle of the night - which is already a problem for the customer. We did not find any issue with the MTA/MTA child (there is no error log/restart during those hours)! Any idea what we can check/ doing wrong
Hi @supratim320 ,
It seems delivery is scheduled to deliver certain percentage or number of emails every hour.
Please check again the delivery 'Properties'. Is it set waves?
If you are not able to find anything, then try to use new/fresh delivery activity. Before adding HTML content, check delivery properties, remove any additional code written in the properties. Then do the HTML part and do the testing.
