Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Adyen

  • There is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic
  • Published fees are indicative rather than a rate card, with real pricing negotiated
  • Interchange++ means the card cost varies per transaction rather than being a single predictable percentage
  • Alternative payment methods carry their own rates on top, such as 3.3 percent plus $0.10 for American Express in North America

Mimecast

  • No pricing is published for any product or plan, and every route ends at a quote or demo request
  • The platform is split into separately sold products for email security, awareness training, data protection and governance
  • Collaboration threat protection, DMARC analysis, incident response and email archiving are all further add ons on top of those
