Looking for more guidance on UTM best practices as we work towards more scalable solutions.
Currently we use velocity script tokens that contain the entire link (since I know not doing so can often cause issues) and we do a data value update right before the email send to update UTM variables referenced in said link.
What I've found odd is that click tracking does work, but it appears to be inconsistent (sometimes the mkttoken hash is appended to the url for tracking; sometimes not).
Is there anything that I'm missing as far as why the clicks would come through sometimes but not always when using the same implementation protocol? Marketo support has advised that our execution is correct so wondering if anyone has struggled with this issue or might have a better solution.
As you can imagine, we're trying to make the click tracking work for script tokens because it would be an immense amount of work to make each email dynamic given the number of custom links/UTM combos we use now and in the future.
Appreciate the help!
