When trying to send a mass mail, a campaign or promotion to our emails list created on the online shop,
our ISP outgoing servers will mark the website's IP as spamming engine and will blacklist the IP.
This happens because (as many other ISPs) they have limitations on their outgoing servers
i.e no more emails than 200 to be sent in less than an hour.
Is there a way (in version 1.5) to break the emails list or when sending mass emails send,
for example, to 50 receipients every hour?
