Validate email address live on the landing page

[Anonymous]

Hi all,

Anyone knows if it's possible to do the following:

When a person keys in his email address in the Marketo landing page form:

• If his email address is already in the Marketo list relevant to the landing page form, he will receive an on-site message saying "he has already signed up"
• If his email address is not in the list, then he will go through the standard form submission process.

This will have to happen live. Any developers here who can point me in the right direction. What do you think I have to do to make this work?

Regards

Fred

Hi Fred,

maybe this approach would help you: Show Custom HTML Form for Known People - Marketo Docs - Product Documentation

But this works only for leads who are cookied.

Thanks Matjaž!

That works for a Known person, however, if you want to tie it to the specific Registration list for that Page, you would need to develop some jquery.

Hi Josh,

Thanks for your insight.

Another newbie question: I'll think Form 2.0 will make this work, but do you know how I can possibly retrieve and compare against a specific registration list using jquery?

Thanks in advance.

FTR: it's not a question of "jQuery" but JavaScript. (jQuery is merely an additional JavaScript library that's not important here, or really anywhere these days.)

Anyway, it is not possible to retrieve list membership directly from the browser using JavaScript.

Were it not for REST API limits, it might be feasible to query a separate server using JavaScript. That server, in turn, would use the API to look up lead membership. But alas, this method can't be used on a public form.

What you can do is:

• submit the form, then check every, say, 1 second for a total 10 seconds for the web session to be associated by refreshing the Thank You page
• once it's associated, you'll see {{lead.tokens}} in the page (that's how you know Marketo has finished merging the lead)
• have a Smart Campaign triggering on Filled Out Form; on the Flow, start with a Wait step of 30+ seconds, then run Change Data Value on a field, for example, memberOfLists
• since memberOfLists won't change until after the 10s polling period has elapsed, you're assured that if you see the name of the list, that means they were already in the list.
• profit accordingly

While bit clunky, this approach could be implemented quickly by a skilled developer.

Hi Sanford,

Thanks for the insightful answer (:

I guess the alternative approach you suggest is not something that can be deployed live, in the sense it takes place when the button is clicked, and based on whether the person is already in the list or not, I can show something different (like different form, url etc.). Am I right to say that?

Btw, here's an example of such a form in action:

Note this doesn't use the server APIs in any way (I would never do that) merely the Forms 2.0 JavaScript API as I described above.

Do you have a sample of your code online Sanford?  I think this is interesting and could potentially soluse-casesecase.

It will be a blog post soon.

Hi @SanfordWhiteman,
is there anywhere the blog post you wanted to write? I can't find it.

We are also wondering if there is the possibilty to display to a (sales) person on marketo landingpage, if a customer is on a list or not just by typing in the customers email address.

Well we could create a link with a querystring of the email address which will be then pushed automatically to the email address field and by clicking on submit the browser will think, that the sales is the customer because of the munchkin cookie. And then we are able to show specific lead.tokens on the landingpage.
But does this also work "live" and does this also work for static lists somehow?

Thanks and BR
Julia

This is a bad idea. You do not want to deliberately associate sessions with the lead when you know for sure it’s not actually the lead behind the browser!

If you want a page that displays {{lead.tokens}} that’s meant for use by internal people, create a new Domain Alias that does not share a private domain with your other LP Domain(s). For example, if your Primary LP domain is pages.example.com register a new domain pages.example-sales.com. Never run Munchkin on any example-sales.com pages. That way a salesperson who clicks an alert link to https://pages.example-sales.com/lead-peek will see the lead’s token values, but there will be no other lingering traces of the lead.

Hi @SanfordWhiteman 

thanks for that idea. Is there somewhere a step by step guide? I do not understand how a sales person can see results of different persons on that special website.

P.S. We did this form thing I described in the past for another thing and we were aware of that muchkin-tracking problem. So we implemented a script on this special website, which expires the munchkin-cookie directly after the form fill out. So that no sales person is crashing the activity log of our customers.

There’s no need to expire the cookie. You just don’t post the Munchkin cookie with the form data, so the re-association never happens.

However, as I mention above it’s better to have a domain that never runs Munchkin at all, so there’s never an association to worry about.

You send them an alert with a mkt_tok-enized link to the LP.

Did you ever publish this Sanford?

[Nav_Singh1]

Great! I'll keep an eye out for it. I think this is probably the only way to accomplish what I'm trying to do. Thanks.

No.... why would I have suggested it if it couldn't be used?  You have ​some guaranteed latency when you perform a remote lookup in response to a button click, and this method might be on the high end of user-facing delays on occasion, but it can be used "live."
