Frequently Asked Questions #

Q: Why am I seeing the error “SMTP Credential creation is blocked. Please contact support…”?

This message appears when your account has hit usage thresholds or restrictions on SMTP credential creation. This could be due to exceeding the daily email limit (e.g., 1,500 emails/day) or internal controls to prevent abuse. Please contact support to review your account status and request increased limits or to resolve any compliance flags.
