It is beyond belief that CC has changed things so much that campaigns (one or a series of email messages to be sent to a List of Contacts) which have been created with the "old" editor have to be completely redone in the "new" editor.  The "old" campaigns will no longer work after the deadline.  Period.

Years ago, Constant Contact was a viable marketing option. However, many people have started 'opting out' of receiving online marketing through Constant Contact and other popular email marketing companies. When you send out your email marketing campaign to "your" group of clients, if these clients have already opted out to received emails through Constant Contact from a campaign sent by someone else, your campaign is not sent to them.

Today, roughly 20% of the people in your email group will receive your campaign.

I am going to respond from the other end. As a small business owner, we get hit daily with emails which we call the new telemarketing way of doing things. We do not like it, if you cannot pick up the phone and get to know my business you will receive a delete button. Today's social media and technology world has created something that now is a non-personal way of selling. Just a piece of advice. 

Constant Contact has a number of features that are great for mid-sized to large businesses, but for small and micro businesses the learning curve is too steep and non-intuitive. The paywall becomes an issue too soon for small businesses on a shoestring budget as well. In short, Constant Contact will have a small business person learning about and paying for lots of features they'll never use. I prefer mail Chimp. It's intuitive for all of the features I'll ever use at the small business micropreneur stage, and by the time I hit the paywall, my business will be able to easily afford a subscription.

We used Constant Contact in my prior business – a complex mid-sized high tech start-up (that did not survive the recession). It was a challenge for the sales staff to learn, and the features we needed were not cheap, but not outrageously expensive. It DID have a number of contact handling features that we needed for a mid-sized business – some fairly powerful sorting, scheduling, and reporting tools.

However for a small business or micropreneur there is such a thing as too much power. More power generally means more features to learn, and without a dedicated sales and marketing person (or part of a person), Constant Contact is just too much OOOMPH to master. The lighter weight software options are sometimes better.

As an IT consultant I have seen Constant Contact mail get blocked because the origin has been blacklisted for spam.

In many cases unscrupulous clients of Constant Contact break the rules and send unsolicited mail and do not ask recipients if they want to receive the mail first. Thus they get blacklisted.

For that reason I can't recommend them and actually rate them lowly for not vetting clients properly and having such high spam ratings.
