If you absolutely *must* load embeds from different domains

Whenever you can, standardize your form embeds on a single Marketo LP domain. But there’s one case where you clearly can’t: different Marketo instances.

Combining Progressive Profiling with (the equivalent of) Known Visitor HTML

Progressive Profiling and native KV HTML don’t play well together, but if you build a KV HTML equivalent using a little CS + JSS, you get the best of both worlds.

Patching a bug with input masks + multiple Marketo forms on the same page

Unbeknownst to (I’m pretty sure) anyone, whether input masks work or not depends on form load order.

The dreaded “Submission failed, please try again” error and how you caused it 😊

Panic-inducing for sure, but every time I’ve seen this error there’s a straightforward cause and easily deployed solution. You just need to know where to look.

Transforming Marketo-incompatible webhook responses using AWS API Gateway + JSONPath + Velocity (!)

Velocity ain’t just a Marketo thing! Having a command of VTL loops and conditions lets you use a totally different environment — Amazon Web Services — to better integrate prepackaged webhooks.

Retracing how a web standard got rumor-milled into incorrect, anxiety-producing conventional wisdom.

Transforming a Marketo ˂select˃ into a so-called “image dropdown” using ddSlick

Non-standard form elements add visual panache. But familiarity, accessibility and (especially) mobility remain concerns, so tread carefully.
