Basically, what I got from a colleague was such a script
<script charset="utf-8" type="text/javascript" src="//js.hsforms.net/forms/shell.js"></script>
<script>
hbspt.forms.create({
portalId: "1234567",
formId: "1111-2222-3333-4444"
});
</script>
which loaded a hubspot iframe form. This, however, is not what I would currently enjoy. I would prefer using my already created form and just sending a signal from that to HubSpot. The form has an email field, checkmark (about email etc) & send button.
How can I send the email from my form? (new to HubSpot btw)
