SamuelGuard lets you test a real email against common spam and deliverability signals, including authentication, content, subject line, message shape, and sender reputation.
A useful spam score checker should look at more than trigger words. Inbox providers consider technical setup, sender reputation, content patterns, links, HTML structure, and recipient expectations.
You forward your email to a unique SamuelGuard test address. SamuelGuard analyses the received message and turns the findings into a spam risk score with readable explanations.
A number is useful, but the fix matters more. SamuelGuard connects each point of risk to something practical, so you can improve the next version of the email.
Spam score testing is useful before sending invoices, newsletters, client updates, product emails, and transactional messages that need to land reliably.
No checker can guarantee inbox placement, because mailbox providers use private signals and recipient behaviour. SamuelGuard shows visible risks you can improve.
No. You can run free one-off public tests without an account. Accounts add saved history, private reports, monitoring, and API access.
SamuelGuard gives you a spam risk score, delivery health, authentication checks, blacklist checks, content warnings, and practical fixes you can act on before the next send.
