As you read on, you might think I’ve contrived a situation with an infinitesimal chance of happening in real life, just for the love of blogging. But this just happened to a user who posted on the Nation! So here’s the weirdest Marketo Forms factoid you may ever learn: if the 20th field added to a f...

You see a series of Unsubscribe Email activities, roughly 5 minutes apart, covering more or less all the emails someone received: Each one’s Details show they used the List-Unsubscribe header: Turns out that’s standard behavior of the newish Manage Subscriptions feature in consumer Gmail. When you g...

Feels weird to be writing about this at such a late date, but there’s misinformation going around, perhaps AI-influenced. The spur for this post was the erroneous claim that Marketo Forms 2.0 uses REST API names as Form Field names. That is, if the REST API name is email the corresponding form field...

Marketo recently added a bunch of new {{trigger.tokens}} that can help reduce the number of nearly-redundant trigger campaigns, always a good thing. Some of the tokens are relatively “raw,” though: they output unique IDs, not friendly names. Massaging those into values suitable for people like sales...

Let me start by noting this technique is only for people at your email domain, not for lead email addresses. Guessing leads’ names is what spammers do. If you forgot to require First Name and Last Name on a lead gen form, complete their profile responsibly. Sometimes, due to technical gaps, you only...

Native Visibility Rules and Progressive Profiling pack immense power. But one thing they can’t do is change whether a field is required: if a field is displayed per VR and/or ProgPro rules, it simply picks up the Required setting from Form Editor. This means you need JS for advanced behaviors. Say C...

You have a robust multi-subscription model using Marketo Custom Objects, where each Subscription+Person combo has robust metadata about when somebody subscribed/unsubscribed, why, and how. The boss goes, “Can we get a scheduled report of people who subscribed to any newsletter in the past month?” Yo...

window.postMessage and corresponding window.onmessage listeners enable secure communication between cross-origin windows, including IFRAMEs. The postMessage API is ubiquitous, used by popular JS widgets like media players (YouTube, Spotify), meeting schedulers (Calendly), chat popups, and forms[1]. ...

A client found a single recipient domain where every Marketo email went to Spam due to failing DKIM validation. (A bad DKIM signature should really result in the message being dropped completely, so sending it to Spam was dangerously generous!) We knew the DKIM DNS record (m1._domainkey.example.com)...
