Centralized customer data has powered predictive audiences and proactive marketing campaigns
The best features Segment offers are the audience building features. We've also launched predictive audiences, which is so far really promising for us and marketing has a lot of ideas for activating these types of audiences. We're going from using historical data to using current data to get more predictive with how we're activating. In my experience, the audience building tools compared to other solutions I've seen or used are really sophisticated. I've used other CRMs in the past for this, and I would say the type of data you're not getting as much of is what you do when you're activating or creating the audiences within the CDP. I think predictive audiences require a 360 view of the customer in order to create these types of AI audiences because they use a lot of different data points. How it's helping the team is by giving us more ways to reach our customers and being more proactive in the type of campaigns that marketing can launch. They have a lot of good ideas and some good things in the pipeline.

Quotes from Members

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

Pros

"Optimizely is a great product that has inspired a great community and is the standard for A/B testing."
"Dead simple A/B testing with no code knoweldge needed."
"Optimizely can work for a lot more things than only testing; it is a pretty easy yet powerful tool."
"Customer service is the best in the testing industry; transparent support along with a very strong community."
"ROI: Infinite! (Got 3X conversion improvement using suggestions given by the product during the free evaluation period)"
"Customer service is wonderful."
"Customer service is excellent!"
"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 has positively impacted my organization by reducing implementation time to one-third of what it previously took."
"Inserting some very simple code snippets has made this part of it a breeze for our developer so he can concentrate on the hard stuff."
"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."
"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'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."
 

Cons

"Better communication with 3rd party implementation"
"When testing images or anything involving JavaScript or more than text, they can really slow down the load performance of a page."
"Does not allow multipage variants (i.e. allows only variants in elements inside one page)."
"Verifying goals could be easier."
"Exporting statistics provide more statistical data."
"There were previously issues with experiments saving as expected in Classic."
"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 only challenge was the session functionality."
"The design of the website is such that you lose context when clicking around (e.g. when clicking on docs)."
"The challenge is the lack of flexibility in the SDKs, given the capabilities of the destinations."
"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."

What needs improvement with Segment?
