Landingi is a good option for landing page beginners because of the good price, smooth onboarding and additional services. You can easily find your way in the editor as it guides you to select a landing page goal and then a template (there are plenty available). All the elements on the page are customizable to the pixel, no coding required.
Plans start at $29/month for aunlimited landing pages, but you'll need to pay $49 for crm integrations, A/B testing, autoresponders and more goodies.
They also offer services like landing page design ($390) or landing page import ($99), where you send your own design (PSD, HTML or JPG) and they import it into your Landingi account.
A 16 days free trial is available and support is always nearby should you need it.
