According to a survey conducted by Pew Research Center, 78% of internet users use the internet on a daily basis. Out of that 78%, 62% of users read or send email on a typical day(1).What this means is that bulk email marketing has become increasingly beneficial for businesses and private marketers.
At this rate, it seems this trend will continue to rise as bulk email marketing begins overtaking traditional mailing services. Bulk email marketing can be sent 24/7 without any interruption. So, you are not obligated to work around someone else's schedule. Instead, you set your own schedule for your particular campaign.
Velocity Marketing Software allows for you to set the speed of your campaign. You can either set it to send out at very slow or very fast. If possible, it is suggested that you send your campaign out at a slower pace. This way, there is a better possibility that more of your emails will be received instead of blocked by your ISP.
The benefits of bulk email marketing are growing as time goes on and more and more businesses adopt this form of advertising as standard practice.
