What Spamarrest does better
Honestly, little to mention today.
- Historical precedence — Popularized SaaS challenge-response in 2002. Real credit.
- US presence — If US-based and prefer local, they're there.
What FrozenSpam does better
- 10x cheaper — €4.90 vs $39.95 for equivalent features (and FrozenSpam has 5 layers where Spamarrest has 1).
- Identifiable service — Emmanuel replies personally. Trustpilot reviews on Spamarrest mention repeated service issues.
- Stable transparent pricing — Spamarrest multiplied prices ~8x over a few years. FrozenSpam contractually commits to 30-day notice on any change.
- Modern 5-layer architecture — DNSBL + SPF/DKIM/DMARC + antivirus + backscatter guard + CR. Spamarrest is CR-only since 2002.
- Outbound auto-whitelist — Zero false-positive guarantee. Spamarrest doesn't have it.
- France hosting + native GDPR — For any European customer, dealbreaker vs US.
