Pros
I've been employed at Constant Contact for about 4 years and never have I seen a company that is so committed and focused on it's employees and it's customers. Constant Contact "gets it". It's one of the few companies that understands that it's all about the employees and customers. The company culture is amazing, everything is transparent and out in the open. The company employees really good people, not just talented people, but people who know how to work as part of a team and are really mission driven. It's really hard to explain but it's similar to what you would see in a west coast company like Facebook or Google, Constant Contact just doesn't get the publicity that those companies do and they don't brag about it. Constant Contact has all the workplace perks that the Sillicon Valley companies have (lots of food, lots of fun, amazing perks like on-site massages, manicures, beer cart fridays, bashes for company milestones, bi-weekly company wide meetings led by the CEO) This is a growing company with a really bright future and it's care and respect for both it's employees and customers really can't be put into words. You have to see it to believe it. The company has also grown countless numbers of employees and is a great place to develop and expand your career.
Cons
No real cons and not a lot ot complain about, I'd say because the company values it's employees so much, sometimes it appears that everyone has an opinion or there are two many cooks in the kitchen. Also, the company's acquisition of Singleplatform has put a great deal of stress on it's existing employees. This is something that management is figuring out.
