It enables me to create and manage an auto-responder series along with list growth management tools.
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…

Retargeting campaigns have reduced booking cancellations but new users still need clearer guidance
I believe that retargeting is the best feature that Insider offers. The ease of use and the results are why the retargeting feature stands out for me. Insider reads the results near real-time and provides AI segmentation. We only need to prompt, and then Insider will work to determine which segment is best for each campaign. Insider has helped me to reduce cancellation bookings by about 15% year-over-year. This is tracked through Insider; however, we also add additional attribution using AppsFlyer. We see significantly fewer employees needed for outbound calls because with Insider, we perform a reconfirmation of booking schedules automatically. This allows us to reduce the need for customer service outbound agents, and Insider has also helped us reduce cancellations.

Quotes from Members

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

Pros

"Every time that we send one out, we will get some kind of response."
"Just like the name states, it has allowed me to stay in "constant contact" with my subscribers."
"It is fun to design your newsletter based on the content you would like to deliver."
"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."
"Email marketing is the most valuable aspect."
"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."
"Insider is simple to use, making it easy to learn and navigate the platform, so the learning curve is fast."
"Insider has helped me to reduce cancellation bookings by about 15% year-over-year."
 

Cons

"There are certain hiccups in the program that can be improved to make it more user friendly."
"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."
"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."
"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."
"Could use better search and certain editing traits."
"I think that Insider can be improved on the UI side because for someone with experience, Insider would be a very great tool."
"I did not enjoy using Insider AI to generate copies, push copies, and messages."
 

Pricing and Cost Advice

"The cost is fair, and you end up making enough in sales to pay for it."
