What SamuelGuard focuses on

SamuelGuard checks the practical signals that commonly affect deliverability and turns them into readable findings rather than leaving you with a raw score.

  • Spam risk score with top findings.
  • Delivery health and authentication checks.
  • Subject line, content, link, image, and message-shape analysis.
  • Blacklist and sender-domain reputation checks.

When to use it

Use SamuelGuard when you are testing an invoice template, campaign email, transactional message, or business email and want clear next steps.

  • Before sending a newsletter.
  • After changing email platforms or DNS records.
  • When invoices or client emails start landing in spam.
  • When you want saved reports and recurring domain monitoring.

What accounts add

Free public tests are good for quick checks. Accounts make SamuelGuard more useful when email testing becomes part of your workflow.

  • Dedicated account inbox.
  • Saved and private reports.
  • Longer retention.
  • Domain monitoring and API access on higher plans.

Why plain English matters

Deliverability is full of acronyms and misleading guesses. A useful report should explain what each issue means and what to do next.

  • Prioritise the fixes that affect trust first.
  • Separate authentication issues from content issues.
  • Use repeat tests to confirm improvements.
  • Keep reports understandable for non-technical teams.
