If I was just starting out I would recommend starting with LeadPages so you have pre-made designs which are less customizable so you can get your head around what’s going on. But if you’ve had a bit of experience or are in the more advanced level, then I think getting a mid ranged ClickFunnels plan would be more appropriate. Either way, I don’t think you should cancel one account before the other, until you have had some time to play around and try them both out.
There’s a better solution: It's not impossible with sales funnel management automation. Set up your system with the response you want, and it will be ready to send it immediately to any interested prospect—even the one who contacts you on Saturday at 3 am. As captured leads pass down the funnel, your sales automation platform can send added personalized emails that are just right for each moment.
