Receiving spam from Postulate?
We work hard to keep spammers off our platform, but despite our best efforts, abusive messages occasionally get through. If you've received unwanted email sent via Postulate, we want to know about it — your report helps us keep the email ecosystem clean for everyone.

Including the complete headers helps us identify the sender and take action faster. We investigate every report and respond within 24 hours.
How we think about abuse
Anti-abuse isn't a side project for us — it's core to our product. Every spammer that sends through our infrastructure hurts the deliverability of every legitimate customer. Protecting good senders means being aggressive about catching bad ones.
We don't pursue the illusion of 100% prevention. Instead, we invest in the interventions that have the highest impact: automated detection that catches most abuse before it leaves our servers, and fast human response for everything else.
What we do proactively
Outbound filtering — all email is scanned for spam signals before it leaves our servers.
Rate limiting — per-account sending limits that scale with trust. New accounts start with conservative limits.
Bounce and complaint monitoring — accounts with abnormal bounce rates or complaint ratios are automatically restricted and reviewed.
Authentication enforcement — all outgoing mail is signed with DKIM and validated against SPF and DMARC policies.
Feedback loops — we process complaints from major mailbox providers and act on them automatically.
How we handle violations
We differentiate between restricting and banning. When we detect suspicious activity, we first restrict — pausing sending, reducing rate limits, or blocking specific features. This protects the ecosystem while giving legitimate senders caught in false positives a path back.
Confirmed abuse results in permanent account termination. We cooperate fully with law enforcement and anti-spam organizations when applicable.
