Email Verifier

Email Verifier

Check whether an email address is deliverable before you send to it.

Examples

• /hunter:email-verifier [email protected]
• "Is [email protected] a valid email?"
• "Check if [email protected] is deliverable"
• "Verify these emails: [email protected], [email protected], [email protected]"
• "Can I send to [email protected]?"

Steps

1. Parse the input. Extract the email address(es).

2. Call Email-Verifier for each email.

3. Present the result with an actionable recommendation:

# Verification: [email protected]
| Check | Result ||-------|--------|| **Status** | valid || **Score** | 91 || **MX Records** | Valid || **SMTP Check** | Valid || **Accept All** | No || **Disposable** | No |
## RecommendationSafe to send. This email address is deliverable with high confidence.
## Next Actions1. Find more contacts at stripe.com2. Enrich this contact with personal details

4. Interpret the result clearly based on the status field:

   • valid (score 80+) -> "Safe to send. This email address is deliverable with high confidence."
   • accept_all -> "Proceed with caution. This mail server accepts all addresses, so delivery is not guaranteed even though SMTP checks pass."
   • unknown -> "Unable to determine deliverability. The mail server didn't respond clearly -- consider sending a low-priority test first."
   • invalid (score below 50) -> "Do not send. This address is likely invalid and will bounce."
   • Disposable email (disposable: true) -> Add: "This is a disposable/temporary email address. It may stop working at any time."
   • Pending (HTTP 202 response) -> "Verification is still in progress. Try again in a few seconds."

5. For multiple emails, verify each separately and present a summary:

# Verification Summary
| Email | Status | Score | Recommendation ||-------|--------|-------|----------------|| [email protected] | valid | 91 | Safe to send || [email protected] | accept_all | 62 | Proceed with caution || [email protected] | invalid | 12 | Do not send |
**Results:** 1 valid, 1 accept_all, 1 invalid

Credit Cost

Costs 1 verification credit per email — only charged for valid, invalid, or accept_all results.

Success Criteria

Verification status returned with a clear, actionable recommendation the user can act on immediately.
