You could use Marketo's tools.
What are you trying to do exactly? OptInMonster does a lot of things. Is it not what you want anymore?
Thanks, Josh. We're using OptinMonster for lightboxes, inline ctas and sidebars to collect email addresses on our Wordpress pages. This pushes into Marketo.
We want to be able to see the opt-in conversion rates and conduct A/B tests on these opt-ins acquisition points. OptinMonster has been really helpful, but we're not able to export data or view analytics in a helpful way.
Have you used AppSumo?
