Unfortunately, we don't have a free plan.
"Free" usually means having to bombard you or your customers with advertising or selling your data to third parties to generate income. We'd rather not have to resort to that type of thing, so we offer a fantastically simple and reasonably priced service.
We DO offer a free 30 day trial and we have we also offer a 100% Money Back Guarantee during the first month of your paid subscription.
