They offer no trial period for this service so take your chances because even if you use it for 1 day and 1 send and it doesn't work properly they will not give you a refund no matter what. Didn't send at the right time, showed them proof it wasn't working properly, that it sent 1.5 hours later at some random time and didn't care, blamed me it must be my fault and would not refund no matter what.
