    Optimizely
    Based on my experience with Optimizely Feature Experimentation, I can highlight several scenarios where it excels and a few where it may be less suitable. Well-suited scenarios: - Multi-Channel product launches - Complex A/B testing and feature flag management - Gradual rollout and risk mitigation Less suited scenarios: - Simple A/B tests (their Web Experimentation product is probably better for that) - Non-technical team usage -

    For businesses requiring advanced email marketing features like sophisticated automation, in-depth analytics, and extensive customization, VerticalResponse might fall short due to its limited featuresVerticalResponse is ideal for small businesses or freelancers who need a simple, straightforward email marketing tool. Its ease of use and basic features make it suitable for those without extensive technical expertise in email marketing

    Pros
    Optimizely
    • It is easy to use any of our product owners, marketers, developers can set up experiments and roll them out with some developer support. So the key thing there is this front end UI easy to use and maybe this will come later, but the new features such as Opal and the analytics or database centric engine is something we're interested in as well.

    • I love the ease of list builder because we often times have a lot of data to import. It would be simply impossible without this tool, considering the amount of customer data we have for any one given email.
    • We really enjoy the ease of use of the HTML wizard as well. It helps even a novice be able to make a beautiful and attention grabbing email.
    • The dashboard is functional and easy to find when you need with a quick search.

    Cons
    Optimizely
    • Would be nice to able to switch variants between say an MVT to a 50:50 if one of the variants is not performing very well quickly and effectively so can still use the standardised report
    • Interface can feel very bare bones/not very many graphs or visuals, which other providers have to make it a bit more engaging
    • Doesn't show easily what each variant that is live looks like, so can be hard to remember what is actually being shown in each test

    • The type face is small. Not sure if this is to avoid overwhelming the reader, but I could see this being an issue with vision-impaired people or people who don't see small print well.
    • Sometimes I find it takes multiple clicks to make one simple change. I wish there was a search field at the top of the screen that allowed me to jump directly to a client's entry to update it there.

    Product is easy for both technical and non-technical people to use. A cost effective solution for sending out large number of messages. We can manage unsubscribes by individual accounts, so we can have multiple multiple accounts combined to maximize our buying power on credits. Effective API for sending/receiving data makes tool a valuable asset.

    Usability
    Optimizely
    Easy to navigate the UI. Once you know how to use it, it is very easy to run experiments. And when the experiment is setup, the SDK code variables are generated and available for developers to use immediately so they can quickly build the experiment code

    I truly love this product. We are moving to an all-in-one system next year and my greatest fear in doing so is how much I will miss this platform. Although we are excited for things ahead, I will always keep Vertical Response in my back pocket incase I don't love the new platform as much

    At Vertical Response the help desk associates are courteous, knowledgeable and helpful. You can tell they enjoy what they do. And clearly, they are well trained because most times, the first point of contact is able to resolve any issue you may have. There have been very few times where an associate has needed to get back to me or escalate me to a supervisor

    When Google Optimize goes off we searched for a tool where you can be sure to get a good GA4 implementation and easy to use for IT team and product team. Optimizely Feature Experimentation seems to have a good balance between pricing and capabilities. If you are searching for an experimentation tool and personalization all in one... then maybe these comparison change and Optimizely turns to expensive. In the same way... if you want a server side solution. For us, it will be a challenge in the following years

    In addition to using Vertical Response personally I also manage email marketing for clients that already use Mailchimp, Robly and Constant Contact. While most of these platforms all offer similar features I choose Vertical Response first if the client does not have a platform in place. Typically I am also teaching the client how to use this tool and the Vertical Response visual interface is very easy for me to teach a client how to navigate and create their own campaigns.

    Return on Investment
    Optimizely
    • We have improved various metrics throughout the course of our experimentation program with Optimizely and therefore sharing numbers is tricky. Essentially we only implement versions of the product that perform the best in terms of CVR, revenue/visitor, ATV, average order value, average basket size and so forth dependent on the north star we are trying to move with each release.

    • We were able to blast out promotions our company was having to customers which created an increase in business.
    • By blasting out any service issues, it keeps our customers informed so that they are not wondering what is going on.
    • Allows us to store unsubscribed emails so that we are not constantly pestering people who do not want to be emailed.
