I love the platform - I am currently using on a trial basis.
I build websites for clients from home and I wish you offered a one off annual fee payment to allow the build of unlimited sites using PRO PLAN.
I do not charge my clients a monthly hosting fee and I build sites fast and sell them cheap (Probably 3 a week on average) - I just charge for site creation.
I prefer your platform to the one I am currently using - you offer me everything I could need but the current price plan is definitely an issue.
Client preview would also be great and no monthly costs - just a one off annual fee to yourselves would be ideal - I am sure this would bring you an awful lot of business from web designers, developers etc.
I personally, do not need a white label solution as long as Strikingly branding can be removed (I also invoice my clients directly) so I would not need that functionality via Strikingly
