I'm using OptinMonster integration with Marketo, which only allows showing 3 fields - Email, Name and Phone.
I'd like to use a different field and therefore I need to use their Custom HTML Integration. However, for using this I'm required to supply form HTML which I can't find anywhere... (I can only see the embed code)
Anyone knows if that can be solved?
If not, which other popup tools are you using and can recommend of?
