By default, when you send a newsletter campaign, Noptin will send out the email to as many subscribers as it can.
This can cause a problem for those of us who use a shared hosting provider, since most of them have a limit on how many emails you can send per hour.
Since Noptin version 1.4.1, you can now set a limit for how many emails Noptin is allowed to send per hour. To do this:-
- Open Noptin > Settings > Emails.
- Find the “Emails Per Hour” field and set the maximum number of emails you want to send per hour. You can also leave this field blank if you want to send as many emails as possible.
