Email newsletters and other marketing blasts provide online operators with a “push” technology for reaching out to prospects, and are a great way to stay in touch with past customers, letting them know about your latest offers. These sales tools can also be used to solicit new business and for sending confirmations of current transactions, solidifying customer’s positive perceptions about your company and its responsiveness.

This ultimately increases website traffic and sales; but various legal and technological complexities have made running and tracking e-mail campaigns difficult — until now...

Calling itself “E-mail marketing software for designers and their clients,” CampaignMonitor.com allows users to create custom e-mail messages with their own tools, or via templates that let clients send their own blasts.

CampaignMonitor automatically handles newsletter signups, “unsubscribes” and bounces, so that e-mail lists are as accurate and as “clean” as possible. Subscribers can be grouped together for niche targeting, allowing for greater flexibility in e-mail marketing communications.

Sophisticated tools and actionable reports reveal more than standard open and click rates, to track and report on conversions and sales occurring as a result of an e-mail blast.

While other e-mail marketing tools may provide similar features, CampaignMonitor stands apart from the pack in that its offering is a customizable white-label that can be rebranded to your desired look and feel — allowing users to set the price that their clients will pay — and then forwarding a payment covering your monthly profits as a reseller.

Myriad downloads, plugins and extensions make integrating CampaignMonitor into your existing infrastructure a snap, while guides, templates and other resources will get users up and running in no time.

Used by leading Internet companies including eBay, Facebook, Intel and Twitter, CampaignMonitor offers a variety of plans starting at $15 per month, with a free trial of the service available.

If you want a powerful, yet easy to use solution for e-mail marketing, this may be it.
