Getresponse doesn't provide a free plan, but as mentioned above, it offers a free trial — it's limited to 30 days, but you can try out all of the Getresponse features using it (for lists that are 1,000 subscribers or less in size)

Monthly payment plans are bracketed by list size, starting at $15 per month for unlimited messages to up to 1,000 subscribers. Full details are available on the Pricing page. With the discounts we offer, you can get 18% off a 12-month plan or 30% off a 24-month plan.

GetResponse allows its members to build basic landing pages (like simple sales funnels), and ClickFunnels allows its members to email new leads and customers. Still, when it comes to email marketing, GetResponse is more versatile. And when it comes to building sales funnels, ClickFunnels is more effective.
