Using acymailing all good but as I have many followers on my newsletter, it takes one day to send to all people. Very long. Is there a way to take less time?
Please tell us how many mails you need to send in which desired timeframe. Also let us know how you configured your send process.
Ideally would like to send newsletter to around 900 emails, in 4 hours. About configuration what do you want to know ? In which window ? I'm in french language.
Please look the following screenshot is it that you want to see ?
Set you automatic send process to 75 mails each 15 minutes. Then go to Configuration->License and make sure your automatic send frequency is set to 15 minutes. This config will send up to 1.200 mails in 4 hours.
