    I have found Google Tag Manager as the go to solution for managing all of your event and conversion tags for your website. Not only does it make it easy to manage all of your tags in the one place, it is fairly intuitive to use and there is plenty of videos and help documentation online to help set up what ever you need. No scenarios come to mind at the moment on where it is less appropriate to use.

    Klaviyo is a leader in the space, but I might recommend it to a colleague for its price point. There are other options that are more affordable and provide most of the tools Klaviyo offers. I also think it can be complicated to use for a new user.

    Pros
    Google
    • Selecting elements on a site [object, class, cookie, etc] (to later fire an event, send some data, etc) is very easy with triggers. Want to add an event when someone clicks on a button? Super easy. It was many many DOM selectors and you can even add custom functions if you need to do something more specific
    • In general, firing events in different circumstances is very easy mixing triggers and tags. You can track almost any element of the DOM and do whatever you want with it.
    • Testing is a great functionality. Only you can see what's on the site and you can debug it easily by seeing which events or tags were triggered and all the DOM elements involved (and why they matched the trigger).
    • Working in environments (staging, production) and versioning is easy to do, deploying changes in 2 clicks.

    • Klaviyo's template builder is very intuitive yet straightforward enough that an inexperienced user can catch on quickly.
    • Their flow builder is also quite intuitive and allows us to build intricate, highly targeted flows.
    • I appreciate their built-in compliance warnings & checks as they apply to opt-out methods, SMS compliance, and overall deliverability.

    Cons
    Google
    • There are several good integrations, but there can always be more. Native tracking for call tracking solutions, analytics providers, non-Google advertisers would be top of my list.
    • Documentation is just dreadful. Luckily there are some awesome folks out there doing crowdsourced tutorials (shout out to Simo Ahava) but by and large the Google Tag Manager instructions are worth what you pay for them.

    • Needs more visible critical notifications as we once exceeded our monthly email limit right during the Black Friday campaign. The notification was not visible enough for us to catch it on time, as a result, some emails scheduled to be sent over the weekend were never sent
    • Better library of dynamic values available for use inside emails

    I haven't found another option for us to use especially one that is free. Down the road we may go a different route but for now GTM is a good option and does what we need it to do. It'd be nice to get more support or more integrations but with the free version there's only so much one can expect to get I suppose.

    Klaviyo is simply a great solution for e-com email marketing & customer relationship management:
    1. User journey visibility: We can see our clients' customers on their individual user journeys (open email, site visits) to better understand and accommodate your customers.
    2. Flow automation: Creating automated emails that follow up with new leads, those who abandoned carts, purchased.
    3. Email design: So easy to use, and more friendly than some other visual builders that we've used.
    4. Metrics visibility: We can see our clients' metrics very easily and adjust efforts accordingly.

    Usability
    Google
    No difficult obstacle to overcome but Google Tag Manager can still be difficult for many users to deploy. Sure the basic HTML script can be deployed quite easily, but when you start to require triggers, variables, etc, it can be a little daunting.

    The only reason why I did not give it a 10/10 is that it cannot distinguish purchases that came through subscription recharges instead of purchases that were driven directly by email sends. Other than that, the automation qualities, design features, and segmentation options make this an incredible email platform, and I am very happy with it

    GTM does not provide support. This is one of GTM's biggest issues but it's due to the level of customization for each website. If your team thinks they would heavily rely on the need for a support staff it is probably better to invest in a paid service with a team that can support your needs.

    Their support is always quick and we have recurring meetings with our advisor. they were great when we first started at walking us through the platform and helping us understand how to do the overall setup. They also have a wide variety of articles that cover must issues in a very clear manner that will get you out of a predicament really fast.

    I thought there was a little bit too much emphasis on AdWords stuff, not enough on the generic application of GTM.

    Planning and communication will help greatly with an in-house implementation. If there are large teams, try to limit the number of people involved to 1-2 developers (back-end dev may be necessary depending on your platform), one analytics marketer and one project manager.

    Don't cut corners, do it right the first time, if you take your time to build everything the way you want it then it will run itself. The platform will help you increase revenue as long as you use the tools it provides. Don't be scared to ask questions, the support team will help you get to the next level

    We moved to GTM from a standard Google Analytics implementation. GTM is much more flexible and easier to make changes, especially as the changes relate to multiple sites and environments. While there is a learning curve when figuring out how to use GTM, I believe the change has been worth it because it helps us understand at a more fundamental level how our tracking works and gives us a lot more control over what we track and how.

    Klaviyo's ability to really tackle the entire marketing contact ecosystem on one platform is what really won us over. The price for everything was competitive, not necessarily the cheapest but competitive, and the ability to see that data flow from every interaction was what was crucial to us. Additionally, Klaviyo is the core of our B2C business. We were not focused on anything other than how we interact with customers directly, and Klaviyo was a direct win for us. The one negative is Klaviyo's ability to work with our B2B side of our business, because it doesn't integrate with platforms like HubSpot. That is a massive downside, but the upside justified the investment.

    Return on Investment
    Google
    • GTM is very useful to determine if a particular element on the site is useful (i.e. is it being watched, is it being clicked, does it help customers navigate through more pages). As an SEO person, I can use this information to decide what to optimize for but also to track progress and see improvements in engagement.
    • With the use of Google Tag Manager, I was able to easily inject an A/B testing tool which lead to several improvements in lead generation.

    • Klaviyo brought our email channel to the top performing channel over Paid Ads several times (according to G Analytics), before Klaviyo Paid Ads were always top and the email channel struggled to even stay in 2nd place.
    • Klaviyo did cost quite a bit more than our old email platform but the ROI was much higher so it paid for itself.
    • Klaviyo implemented tools that allowed us to have a higher customer satisfaction with things like letting customers choose to receive less emails instead of unsubscribing.
