One of the features I didn't like in Constant Contact, besides a temperamental WYSIWYG, was that you were limited to only one autoresponder series. That limits the ability to automate your email lead nurturing, as well as decreases the effectiveness of segmenting your list. Both of which are important to a strategic online marketing campaign.
This morning, Constant Contact sent an announcement to their Solution Providers that they have updated their features and you can not only create an unlimited number of autoresponder series, you can have an unlimited number of emails in that series.
This is great news for my clients who prefer using Constant Contact for their email marketing. I look forward to helping them implement new online marketing strategies.
