Email Deliverability Troubleshooter

Work through the most common reasons your email lands in spam: SPF, DKIM, DMARC, reverse DNS, blocklists, and content, with a fix for each.

0 / 15 checks passed0%, High risk

Self-assessment, not a live scan. This checklist relies on what you mark off, it does not query your DNS, inspect message content, or check any blocklist. A 100% score reflects best-practice coverage, not a guarantee of inbox placement, which also depends on engagement and recipient-side reputation. For a DNS-backed result, pair it with the DMARC / SPF / DKIM lookup tools.

SPF

SPF record published in DNS

SPF ends with -all or ~all (not +all)

Sending IPs are covered by your SPF record

DKIM

DKIM key published for your sending domain

DKIM key length is 2048 bits or larger

DKIM signature covers From/Subject/body

DMARC

DMARC record published (_dmarc.yourdomain)

DMARC policy is quarantine or reject (not none)

DMARC aggregate reports configured (rua=)

Reputation

New sending IP/domain was warmed up gradually

Mailing list uses confirmed opt-in

One-click unsubscribe header present

Content

Text-to-image ratio is reasonable (>60% text)

No link to suspicious or blacklisted domains

Subject line avoids spam trigger words

Frequently asked questions

What is the most common reason email lands in spam?

Missing or misaligned DMARC policy is the most frequent culprit for legitimate mail landing in spam. A valid SPF record + DKIM signature + a DMARC policy of at least p=quarantine signals to receiving servers that your domain is managed and authenticated.

Will fixing SPF/DKIM/DMARC guarantee inbox delivery?

Authentication is necessary but not sufficient. Content filters, your sending IP's reputation, recipient engagement rates, and volume patterns all contribute. Authentication removes the biggest structural blocker, content and reputation work comes after.
