Know your spam score before you hit send.
MegaScore runs your email through a real spam engine and returns the exact score a receiving server would compute — the fired rules, an AI fix for each, and continuous domain-auth + blacklist monitoring.
Real engine scoring
Not a word-counter — a genuine spam engine scores your actual MIME and shows every rule that fired.
One-click AI fixes
Each issue comes with a plain-English fix you can apply instantly, from content to authentication.
Always-on monitoring
SPF/DKIM/DMARC, 50+ blacklists and reputation are checked on a schedule, with alerts when something slips.
A Mail-Tester-grade check, built in
Paste or send a message and get a combined score out of ten — authentication, reputation and content in one verdict — with a real inbox seed test for the truest result.
- Score your real sent MIME
- Seed-inbox real-send test
- Combined /10 auth + reputation + content
- Per-workspace history & trends
Stop bad sends before they leave
An optional egress gate scores every campaign email at send time and can warn or hold anything that would land in spam — off, warn, or strict, per workspace.
- Off / warn / strict policies
- Holds risky sends automatically
- Fail-soft — never blocks a healthy send
Questions, answered
Is this a real spam engine or a checklist?
A real, self-hosted spam engine scores your message the way a receiving mail server does, then layers on our own authentication and blacklist checks for a complete picture.
What is the MegaScore /10?
It combines three halves of deliverability — sender authentication, domain/IP reputation, and message content — into one number you can act on, with the fired rules listed.
