Hi All,
I have installed phpList on my own host provided by GoDaddy. Also make configuration of each single parameter and everything working properly and smoothly.
Unfortunately, before couple of hours I had face unexpected issue, which is received mail delivery failure when I process with new campaign whereas same campaign with template was in use today morning.
It anyone suggest a solution for me?
Thanks for all of you guys.
You should look into the number of messages per hour that GoDaddy allows. I believe it is something like 250 or so.
Set your sending speed to something like 200/hr, and see how that works.
After sending emails and creating a history of bounce rates, you can ask godaddy to increase the number of emails that you can send an hour/day.
Thanks a lot for your prompt response, i have waiting 24 hours but unfortunately i got nothing 
is any another suggestion?
