Marketing team has gained self-service access to clean customer data and runs targeted campaigns
Amperity offers very clean data and good analytics as its best features. Amperity helps with data cleanliness by removing all duplicates, consolidating all multiple data and repetitive data, and they do a great job on cleansing our data and making it into information. Amperity has positively impacted my organization because our marketing and e-commerce team does not require the IT team's help anymore; they are very self-driven and operating under a self-service model, and I am very happy to have that solution. This shift to self-service has led to measurable results, such as the ease of pulling the data using AI functionality and the speed of getting data because everything is so easy to use.

The goal is to continue to engage with my list. Keeping in touch with new and potential customers helps stay "on top of mind" when needing services.  Just like the name states, it has allowed me to stay in "constant contact" with my subscribers. The most valuable features are creating and…

Quotes from Members

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

Pros

"Amperity offers very clean data and good analytics as its best features."
"Amperity has positively impacted my organization by helping improve visibility into customer data and supporting better decision-making."
"The ability to email clients using templates setup in the system."
"It is fun to design your newsletter based on the content you would like to deliver."
"Just like the name states, it has allowed me to stay in "constant contact" with my subscribers."
"Email marketing is the most valuable aspect."
"Every time that we send one out, we will get some kind of response."
"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."
"Customer Service: Outstanding, with email, chat and call capabilities even on weekends."
 

Cons

"Amperity needs better onboarding documentation."
"Could use better search and certain editing traits."
"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."
"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."
"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."
"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."
