Email is tough: Major European Payment Processor's Emails rejected by GWorkspace
A basic email bug is blocking signups for a top European fintech company.
Deep Dive
Viva.com, a major European payment processor, sends verification emails without a Message-ID header—a standard recommendation since 2008. Google Workspace servers reject these emails outright with a 550 bounce error, preventing signups for users with corporate email. The company's support dismissed a detailed bug report, stating the user's workaround (using a personal Gmail) meant "no issue." This reveals a critical infrastructure flaw in a key financial service provider.
Why It Matters
If a top payment processor can't send compliant emails, it questions the reliability of core European fintech infrastructure.
