What Is the Email Deliverability Checker?

The Email Deliverability Checker reviews pasted email text for a small set of content signals. It looks for phrases from a fixed trigger list, uppercase letter sequences, and repeated exclamation marks. The result is a score out of 100 with warnings that can guide a quick copy review before you send a campaign.

Although the tool is named a deliverability checker, it does not test inbox placement. It does not inspect domain authentication, sending reputation, recipient addresses, email headers, or server configuration. The score is a rule-based writing aid, not a probability that an email will arrive. Use this email spam word checker to spot potentially overpromotional wording, while handling technical deliverability checks through appropriate separate processes.

How to Use the Email Deliverability Checker

Paste your draft into Paste your email content. A nonblank entry immediately displays the Deliverability Score. There is no Analyze button. Edit the text directly to see how the score and warnings change. The interface displays detected trigger phrases as labels, an uppercase warning when applicable, and an exclamation warning when there are more than two exclamation marks.

The score starts at 100 and subtracts 10 points for each distinct listed phrase found, 15 points if the text contains a sequence of at least four uppercase letters, and five points for every exclamation mark beyond the first two. It cannot fall below zero. Matching is case-insensitive for phrases and uses substring checks, so a trigger can be detected inside a longer word. Repeating the same listed phrase does not create additional phrase penalties.

Practical Email Copy Review Examples

  • A promotional email containing buy now and limited time will flag both phrases. Use the warnings to consider whether the offer is being described clearly rather than aggressively.
  • A draft containing a four-letter uppercase acronym can trigger the uppercase rule even when the acronym is legitimate. Review the context instead of deleting useful information automatically.
  • A message with several exclamation marks can be revised for a calmer tone, then checked again immediately.

The fixed list also includes phrases such as free, winner, click here, act now, urgent, and guarantee. These matches are broad cues, not proof that a message is spam. A useful review considers whether the wording is accurate and appropriate for the recipient, rather than chasing a score at the expense of meaning.

Tips for Interpreting the Score Responsibly

  1. Treat the result as a checklist prompt. A score of 100 means no deductions under these specific rules, not confirmed inbox delivery or approval by a mailbox provider.
  2. Check flagged phrases in context. Substring matching and ordinary business language can produce warnings that do not require removal.
  3. Keep claims truthful. Replacing a trigger phrase with a synonym does not fix a misleading offer, false urgency, or an unsupported promise.
  4. Review technical sending factors separately. Domain authentication and reputation are outside the tool, and a clean copy score cannot diagnose them.
  5. Recheck the final version you plan to send. Small wording changes affect the local score, but this tool does not run a live sending test, track campaign results, or certify compliance. Keep that boundary clear when sharing its output with colleagues.

Frequently asked questions

Does a score of 100 guarantee inbox placement?

No. The score only reflects the implemented text rules and does not test actual delivery.

Does it check SPF, DKIM, or DMARC?

No. It only examines the pasted text for fixed phrases, uppercase sequences, and exclamation marks.

Why was an ordinary word flagged?

Phrase matching uses substring checks, so a listed term can match inside a longer word.

Do repeated trigger phrases lose more points?

The same listed phrase is counted once. Different listed phrases each deduct 10 points.
