Expandable/collapsible sections within an email

[Matthew_Antos-L]

A colleague has asked if it's possible for us to include expandable/collapsible sections within an email built and sent with Marketo (i.e. only a heading would immediately appear, and the user could click to expand to see the full text).

Obviously, this is a fairly simple task on a webpage, but I've not seen it done in email. Is it possible?

Yes, but it will only work in more advanced email clients like Apple Mail and iOS. What is Progressive Disclosure in HTML Email Design? | Campaign Monitor

A strategy point...email should be a vehicle for action, so if the content lives somewhere else (like your site), why not use the header or teaser content to point them back there?

Hi Matthew,

It's definitely possible--you'll just have some inconsistency in how it's applied across all email clients. Do note that coding this kind of feature is not for the faint of email-hearted. That said, a couple of examples are here:

Thanks Jason, Courtney,

As I suspected. Thank you for the additional links!
