Yes!
We use the term "pause" subscription because the reality is -- you can still access your account as often as you like. You just can't create new drafts. You may however continue to access and edit previously created drafts.
You will still be able to access your account, but your remaining optimizations will stop refreshing at the end of the current payment period.
Please note that your remaining credits do not roll over to the following payment period. If you cancel your subscription it is recommended to use your remaining optimizations prior to the end of the payment period.
