Email marketing has proved to be one of the most effective digital promotion techniques, with its capacity to reach a vast audience very quickly and at the lowest cost. That is why it's important not to underestimate the technical aspects of email delivery.
Now common email providers like Yahoo! Mail or Gmail do not allow you to send unlimited emails at once: they have some strict limitations both for the number of messages and the number recipients you can handle per day.
So if you're starting an email campaign and you need to mail out a newsletter to a large number of accounts, you need to use a professional SMTP service. That is, a monitored outgoing server that allows sending unlimited emails with no concerns, maximizing your delivery rate.
It is generally used for legitimate mailings, such as for email list subscribers. Since the bulk email software usually sends email via direct send and via bulk email service, the use of a bulk email software for spam is almost impossible, because of the large amount of emails that are sent in a spam campaign.
Bulk email software usually refers to a standalone software, while there are bulk email sending web-based services as well.
Most Bulk Email Software programs are hosted by third party companies who sell access to their system, some examples of this type of platform include Mailchimp, Aweber, Get Response, Constant Contact, and Campaign Monitor. Customers pay per send or at a fixed monthly rate to have their own user account from which they can manage their contacts and send out email campaigns. Generally the advantage of this type of program is the reliability of the third party vendor and their application.
Some Bulk Email Software programs are self-hosted like UltraMailer or Sendy. The customer buys a license or develops their own program and then hosts the program. Generally the advantage of this type of program is the lack of ongoing monthly fees to the owner/developer of the program. The disadvantage to using this option is that delivery rate is reduced as often users use one server to send bulk emails. There are various settings to tweak to avoid a server being labeled as spam.
