AI-generated overview

Checks whether an email address is deliverable using DNS and SMTP verification, then gives a send recommendation.

What it does: Parses one or more email addresses and runs an Email-Verifier check on each. It reports status, score, MX records, SMTP check, accept-all and disposable flags, and turns the result into an actionable recommendation. For multiple addresses it produces a summary table with per-address status and recommendation.
When to use it: Use when someone wants to know if an email address is valid or deliverable before sending. It suits single-address checks, batch verification of a list, and assessing bounce risk.
Requirements: Requires access to the Email-Verifier tool or service, which performs the DNS and SMTP checks. Verification consumes credits (1 per email, charged only for valid, invalid or accept_all results). No scripts are included.

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

Parse the input. Extract the email address(es).
Call Email-Verifier for each email.
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

# 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

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."
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

# 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.
