camapaign email very slow

[marshalshamim]

Hi team,

The campaign email that I have sent is very slow. One email is getting processed in one hour.
I did not find any sloution from previous posts.

How can we fix such issue. It was working fine till today. It suddenly stopped the campaign emails.
It says sent or attempted as 10 and in progress as 1.

Did you set the number of emails to be sent by batch ?

How much time between your batchs ?

How frequently is your cron ?
