Most internet service providers (Gmail, Yahoo, MSN/Hotmail, etc.) place limits on the number of recipients for a single message on a given day. This restriction has given a boost to email marketing services such as Constant Contact, Mail Chimp, Vertical Response, and I-Contact. These services not only allow users to send mail to large numbers of readers with the press of a button, but also provide statistical feedback on the number of “opens,” along with an array of other benefits, not the least of which is the ability publish an attractive newsletter with interesting graphics.The industry leaders among small businesses and not-for-profits (as well as in Tres Dias communities) are Constant Contact and Mail Chimp. The few independent comparisons that exist give Mail Chimp a clear heads up when it comes to cost (a “forever free” policy for fewer than 2,000 subscribers), weigh the two services as equal in functionality (templates, editing software, list management, etc.), but place Constant Contact in the lead when it comes to customer support.Our conversations with a handful of communication chairmen in TD communities confirm these findings. Users of Mail Chimp had consistently positive comments about the price and usability and say that customer support is acceptable. Our own experience with Constant Contact underscores the quality of customer support (a “live” person answers the help-line phone on the first couple of rings), but also confirms that the service can get pricey with the add-ons (image storage, archiving, etc.).We invite your response to this article and the previous article.
