Hello Anand,
Thank you for the reply.
This value means the number of email messages sent at a time per step. The default delay between steps is 10 seconds. So it means that if you have 20 subscribers (e.g.) and you keep the 10 value in the
Number of email messages that can be sent at a time text input field, e-mails to the first 10 subscribers will be sent first, there will be the delay of 10 seconds and emails to the rest 10 subscribers will be sent. You can try increasing or decreasing this number and see if it helps you.
If you still experience this issue, I suggest that you should better contact us via
Customer Help Desk and provide temporary access to your server by clicking on the
Add record link on the
Access information page of your Help Desk account so that we could examine the issue in more detail.
Thank you.
