Getting the right email blast program
You could use your Hotmail, Gmail or Yahoo account, but if you need something professional and fool proof and want to avoid being labeled as a new zealand consumer email list spammer, it is a much better idea to use an email blast program provided by a professional email marketing company like Benchmark Email. Benchmark's partnerships with elite consortia like the Email Sender & Provider Coalition (EPSC) and leading deliverability experts like Return Path give you the best chance of getting a prospect to the inbox, which is a major challenge in email blast marketing . Benchmark Email even has built-in data merging features, which allow you to import contact information from different databases so you don't need to re-enter long email lists. In addition to this, you can also customize your messages in the easy-to-use HTML editor before sending them out to your customers and prospects.

Send Email blast to the right people
Another key aspect of any email blast is the target audience. Make sure you're hitting inboxes where the likelihood of response, purchase or interaction is high. If you're firing off too many emails like a loose cannon on a mobile deck, you could put off prospects and customers (if you make it to their inboxes!), tarnish your image and end up wasting a ton of time, money and effort.
Instead, use a high-quality opt-in email list that you've built over time and run a targeted email blast campaign where recipients want to receive your email. The advantage of using a professional email blast service like Benchmark Email is that you know how many recipients are opening your emails, clicking through, and bouncing in a decipherable campaign report. Not only this, you also get access to useful tools like customizing signup forms for your website, double opt-in tools like Permission Pass, and much more.
