How Certain makes it more stressful

Requires in-depth technical experience

Certain was designed by programmers, so it’s non-intuitive and difficult to use if you don’t have a programming background. You will need to have advanced HTML/CSS knowledge to use Certain effectively.

Old and complicated technology

Certain is a very clunky and outdated platform that makes simple operations complicated. Certain is a technical solution, and you will only be able to leverage the edit features with advanced HTML/CSS. 

Long and challenging implementation

Certain is very sophisticated, and your marketing operations and web teams will need to be involved during implementation. Certain takes significant amount of time and investment to properly set up the solution for your company, so it doesn’t make sense to adopt their solution if you’re running a few events.
