Whichever you choose, you add its SPF, DKIM and DMARC records to your domain. We set up the connection and test delivery before go-live.
All charges are billed in US dollars. Plan prices are the published CandidatesPrep rate card. Your storage and email providers bill you directly in USD, and any tax on those follows their terms.
Recording sizes come from measured CandidatesPrep sessions: about 1.2 MB a minute for the screen, and at most 6 MB a minute more with the camera at its 0.8 Mbps cap. Still scenes usually come in well under that.
