Trials are the size of Starter

Cancelling in a trial
Cancelling during a trial ends it at once and you are not charged. Nothing is deleted, so you can pick a plan again later.

What Folderly does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- A free trial of the core product
- How long the free tiers last
- Whether free tools need an account
- A free trial of the core product
- The terms of the new-registration special pricing
- The length of an enterprise pilot
- How many free tests Pulse covers
Where the sources disagree
We report each version rather than pick one.
- The overview page says special pricing is available for new account registrations. Its terms mention a pilot term for enterprise proposals. Neither describes a free trial.
- Free tests: the overview and home pages offer demos only, while the pricing page and Inbox Insights page show free tests. We treat the free tests as separate products and the core product as demo-led.
