That was among the conclusions made by JupiterResearch, a division of JupiterKagan, in its vendor evaluation report, "E-mail Marketing Buyer's Guide, 2006," which was released Thursday. In it, JupiterResearch assesses 28 ESPs on "overall value, suitability and breadth of addressing the distinct needs of marketers."
"As the e-mail market becomes increasingly mature, ESPs that lack tight integration with their clients, or a satisfying process and service experience, are susceptible to client churn," said David Daniels, VP-research director and lead author of the report, in a statement.
More than half of e-mail marketers (55%) said that the reputation of the ESP is their most important consideration in making a selection.
