I have the beta version of PageDyno and was having a problem with linking my API in my mailing list provider. The response was great and the technical team sorted it all out very rapidly. There was, of course, a need to get into both accounts but that was overcome easily.
The ‘Pagedyno’ product is great (which is what I expected as I also use Productdyno).
Thanks to all at PromoteLabs.
