Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is fun to design your newsletter based on the content you would like to deliver."
"The fact that we have been a customer for so long indicates how vital this solution is for our organisation."
"Customer Service: Outstanding, with email, chat and call capabilities even on weekends."
"Email marketing is the most valuable aspect."
"Every email I send, gets people to click on something or contact me, and it works."
"Customer Service: Very good but I would have liked to have 24 hours accessibility."
"The ability to email clients using templates setup in the system."
"It's a very easy product to set up."
 

Cons

"When I started using Constant Contact creating email was very flaky, in terms of crashes and usability (perhaps compared to Weebly etc.). It has improved, however, still needs improvement and email creation still seems clunky and limited compared to other online solutions or website building tools."
"Could use better search and certain editing traits."
"There are certain hiccups in the program that can be improved to make it more user friendly."
"Sometimes, you will be typing in a text box and hit the backspace, but the website will think you meant to go back a page. Basically, you end up losing work when this happens and it is hard to predict."
"All Constant Contact wants to do is keep you on a monthly subscription, so if you only want to send out emails on a quarterly basis you must either pay every month you do not use the product, or you must cancel your subscription and then re-open an account every quarter."
"The solution needs better templating and email validation."
 

Pricing and Cost Advice

"The cost is fair, and you end up making enough in sales to pay for it."
"We pay $80 a month to use the solution."
