The maximum parseable + loggable length of a Marketo webhook response is 10,000 bytes

Something for my fellow push-it-to-the-limit Marketo pros. Discovered this when sending a ton of debug info back from a FlowBoost webhook. (Not to map that info →

No, you cannot use the {{Lead.Email Address}} token in the From: header!

Apparently, people still try this. The business case might be okay (though old-fashioned) but it’s technically doomed. →

Temporarily show hidden field values (for debugging conversion tracking scripts)

Outdid myself with this one, I must say. Already using it with multiple clients — plus running the code on random websites out of curiosity. Think you’re gonna love it. →

You didn’t hear it from me, but this is how you’d set a mktoVariable from a script running in the Preview pane

Not that you’d ever want to do anything like that. →
