There are thousands of types of form tools available. While we can’t create an exhaustive list of all forms we integrate with, we can confirm SparkLoop is able to work with the following form tools.
Form Tools that work with SparkLoop
Mailchimp (all SparkLoop tools except Upscribe)
HubSpot (but needs to be embedded as plain HTML, not the default iFrame option)
SendInBlue (embeddable forms, but not SendInBlue's inbuilt landing pages tool)
Email Octopus (embeddable forms, but not Email Octopus' inbuilt landing pages tool)
Campaign Monitor (but not their pop-up forms)
Gravity Forms (but need to enable HTML5)
Wix native forms (but only the native forms, any other form embedded in Wix won't work)
Opt-In Monster forms
Custom-coded forms (using our manual tracking instructions)
Forms we can't support due to bugs and/or missing functionality
Beehiiv embed forms (however, Beehiiv's own website tool does work)
Forms we can't say whether they'll work or not
... any other form tool not mentioned on this list
You'll need to test the above forms yourself. We can't help with this.
