Read results, not just pass/fail

Each checker explains methodology so your team knows what to fix—and what not to panic about.

Authentication

SPF, DKIM, DMARC, DNS, and MX validation.

Reputation

Blacklist, domain reputation, and placement tests.

Content & hygiene

Spam scores, template checks, and email verification.

All checkers

Deep pages with definitions, outcomes, and how CloudJet fits.

Spf Checker

Check SPF records for your sending domain. Validate SPF syntax, DNS lookups, include chains, and alignment before mail fails authentication.

Dkim Checker

Check DKIM DNS records and selector alignment for your sending domain. Catch key rotation mistakes, missing selectors, and signature failures early.

Dmarc Checker

Check DMARC DNS records, policy (none/quarantine/reject), and alignment requirements. Fix authentication gaps before receivers enforce strict policies.

Blacklist Checker

Check if your sending IP or domain appears on email blacklists (DNSBL). Interpret listings and plan delisting with root-cause fixes.

Email Verifier

Verify email addresses before sending. Check MX records, mailbox existence signals, and risky addresses to protect domain reputation.

Spam Checker

Analyze email content and headers for spam-filter patterns. Catch trigger phrases, link issues, and authentication gaps before sending.

Domain Health Checker

Run a consolidated domain health check: SPF, DKIM, DMARC, MX, and common DNS misconfigurations for email sending.

Domain Reputation Checker

Check domain reputation signals for email sending: authentication health, blacklist status, complaint patterns, and placement risk indicators.

Dns Checker

Diagnose DNS issues for email sending: SPF, DKIM, DMARC, MX, CNAME conflicts, and propagation problems that break authentication.

Mx Record Checker

Look up MX records for any domain. Identify mailbox providers, mail routing, and receiving infrastructure behind an email domain.

Inbox Placement Test

Test inbox placement across major mailbox providers. See whether campaigns land in primary inbox, promotions, or spam before scaling volume.

Email Template Checker

Check email templates for spam triggers, broken HTML, link issues, and authentication requirements before launching campaigns or sequences.
