We use the GTW adapter for webinar registrations. Everything seems to flow smoothly, except when someone registers for a webinar a few mintues before the webinar starts. We had 2 people recently do this and neither received the confirmation email (email confirmation coming from GTW). They are registered in GTW and in Marketo both (no failures there), but no confirmation email showed up in their inboxes. Is there a time cut-off with GTW that it no longer sends confirmation emails once the webinar has started?
