Today MarketingSherpa released two new Buyer's Guides -- Buyer's Guide to Email Service Providers 2006 and the companion report, Buyer's Guide to Independent Email Deliverability Firms. More details at http://sherpastore.com/store/page.cfm/2003

The Buyer's Guides are designed to help marketing and publishing professionals select the right email service providers (ESP) for their needs, and judge email deliverability by using a third-party firm. The Guides assist marketers:

1) Easily compare and contrast 85 email services offered by 64 vendors to North American email marketers

2) Create a short-list of the ESPs for any budget featuring the services considered mission-critical (such as RSS feeds, Web analytics integration, and/or email design and strategy.)

3) See who hundreds of named clients from AARP to Ziff Davis use to send their email newsletters and marketing campaigns. (Complete list of named clients is available at http://sherpastore.com/store/page.cfm/2003 )

4) Determine appropriate pricing, and weigh the in-house versus outsourcing dilemma.

5) Hire an independent third-party deliverability firm to doublecheck ESP vendor delivery claims prior to making final vendor selection.
