Preview form prefill for testing

[BenCirillo]

Hello, 

I am migrating our email preference center over to a Marketo form and landing page. I am going to use Boolean fields with form prefill enabled. 

Is there a way to preview the form as different users to test the prefill function and make sure it is behaving properly? Similar to the way you can test tokens on an email as different users. I tried previewing the landing page using the View as Person option, but it had no impact on the form. I just want to be able to verify that the form works the way it should before unleashing it on the wider world.

Hello!

No, I don't think you can. Form Pre-Fill only works after real email sends, not via sample sends (where you could define another person to populate email tokens from). But what you can do is e.g. to create a bunch of test people in your database with email addresses you can receive and send a test email to a list of these addresses. ben.cirillo+1@gmail.com, ben.cirillo+2@gmail.com ... - and give these records in your database different preferences and such - just to see if the pre-fill works.

Michael’s right: it’s not possible to preview native Pre-Fill within the Marketo UI because the feature is restricted to pageviews originating from tracked clicks — and even then has additional restrictions, i.e. your session can’t be associated with another lead.

Remember, you can only test click tracking itself with a real email, not a sample!

(Even if you’re using my cross-domain Pre-Fill JS instead, that too can’t be tested unless you have a properly associated Munchkin session.)

I do have a couple of different leads associated with variations on my Gmail account, like Michael suggested. Would I be able to send an email to all these leads and test on the same device if I cleared cookies after each view?

Sure! But not all cookies, just the Munchkin cookie.

Or you can open the link in an Incognito/Private window and close that window after each test.
