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…

I have not used Segment for more than a year, so I am not aware of its current evolution, but I know there was a migration from Segment to Adobe as a strategic decision by XP bank, which pointed out unified databases as an improvement area compared to Segment, where they effectively utilized AI for creative marketing campaign generation. The necessary improvements in Segment based on my experience focus on providing more tools for the marketing team, particularly using AI to create campaigns through images and short videos, enhancing communication with end customers via offer banners in a more automated and effective manner.

Quotes from Members

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

Pros

"Just like the name states, it has allowed me to stay in "constant contact" with my subscribers."
"Customer Service: Very good but I would have liked to have 24 hours accessibility."
"It is fun to design your newsletter based on the content you would like to deliver."
"Every time that we send one out, we will get some kind of response."
"The fact that we have been a customer for so long indicates how vital this solution is for our organisation."
"The ability to email clients using templates setup in the system."
"Customer Service: Outstanding, with email, chat and call capabilities even on weekends."
"Every email I send, gets people to click on something or contact me, and it works."
"Segment has improved our data quality and our ease of collection, and most importantly, it has saved us time by not having to maintain a custom tool for server-side tracking."
"Customer support is fantastic."
"I like the straightforward way of connecting with various data sources and destinations. That's the most valuable feature. It has built-in integrations for a lot of them, so the overall effort required for integrations is relatively low."
"Segment's scalability is amazing, and it's fully capable of handling all of the different use cases that we have in our company and we have a very complicated company."
"With Segment, we were able to clean the data and also break the data into different classes to reach specific targets with a specific message, and the outcome was very superb."
"Segment has positively impacted my organization by enabling my client to improve their marketing and understanding of their customers through the use of Segment without needing IT as a bottleneck."
"Segment has positively impacted my organization by reducing implementation time to one-third of what it previously took."
"On the one hand, Segment has saved marketing costs, which has allowed me to use that investment elsewhere, and on the other hand, it has allowed me to do much more personalization than I could do manually."
 

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."
"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."
"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."
"There are certain hiccups in the program that can be improved to make it more user friendly."
"Segment can be improved in the initial phase regarding data quality checks between different channels' attribution versus Segment itself."
"I chose a rating of eight out of ten because these video tutorials would really illustrate how to use the tool to its full potential, and perhaps some more hands-on support from the Segment team would push it to a ten."
"Segment could be improved by allowing community-based integrations, particularly for integrations available only via webhook that are not natively available, such as those from attribution platforms."
"The cost is very high, but it is worth it."
"I have not used Segment for more than a year, so I am not aware of its current evolution, but I know there was a migration from Segment to Adobe as a strategic decision by XP bank, which pointed out unified databases as an improvement area compared to Segment, where they effectively utilized AI for creative marketing campaign generation."
"As data volumes, event tracking, and integrations increase, the platform can become expensive for growing organizations."
"Regarding Segment's AI capabilities, I think its accuracy and reliability of output were lacking."
"Segment scalability is good when it comes to geographic enablement but it is not scalable in terms of data. As I mentioned before, when different streams of data change, it might not incorporate once the data is set up."
 

Pricing and Cost Advice

"The cost is fair, and you end up making enough in sales to pay for it."
"The pricing was on the higher side but it wasn't excessively high."
