A4.2/5.0
Scored across 12 tools
Disambiguation5/5
Every tool has a clearly distinct purpose: header analysis, blacklist check, disposable check, domain health, typo detection, DNS generation, credit balance, verification status, SMTP code lookup, and three verification levels (single, small sync batch, large async batch). No two tools overlap in function or trigger confusion.
Naming Consistency5/5
All tool names follow a consistent snake_case verb_noun pattern (e.g., check_domain, verify_email, generate_dns_record). The naming is predictable and makes the tool's purpose immediately clear.
Tool Count5/5
12 tools is well-scoped for an email verification service. Each tool serves a distinct function—verification, diagnostics, and DNS helpers—without bloat or missing essentials. The count is within the ideal range.
Completeness4/5
The surface covers verification at multiple scales (single, small batch, large async), plus supporting checks (disposable, typo, blacklist, domain health, header analysis) and SMTP code lookup. Minor gap: batch verification only returns a summary, not per-email results, which may require additional calls or dashboard use.
Available Tools
12 toolsanalyze_email_headerAnalyze an email's headersARead-onlyInspect
Read the hidden technical details of an email (its 'headers') to show the route it took, how long each step took, and whether it passed spam/authentication checks - handy for figuring out why a message was slow or went to spam. Paste the message source / 'Show original'. No credit used. Available on the Qualisend Pro plan.
Inputs: raw (required).
check_blacklistCheck a domain or IP against email blacklistsARead-onlyInspect
Check whether a sending domain or IP is currently on any of the major email blacklists that can push your mail to spam - a point-in-time reputation check across lists like Spamhaus, SpamCop, and Barracuda. No credit used. Requires the Qualisend Blacklist Monitoring add-on. Read the result carefully: listed_on are confirmed listings, while undetermined_on are lists that did not answer (commonly Spamhaus refusing a shared resolver). clean is true only when every list answered and none matched, so a non-empty undetermined_on means those lists are UNKNOWN - do not report them as clear or as listings.
Inputs: target (required).
check_disposableCheck if an email is throwaway / generic / freeARead-onlyInspect
Tell whether an email address is a throwaway/temporary one, a generic team inbox (like info@ or support@), or a free consumer address (like gmail) - useful for spotting low-quality sign-ups. No credit used. Available on the Qualisend Pro plan.
Inputs: email (required).
check_domainCheck a domain's email setupARead-onlyInspect
Check whether a domain is set up to send email that reaches the inbox - its mail servers plus its SPF and DMARC sender-authentication, and what's missing. A plain deliverability health check for a sending domain. No credit used. Available on the Qualisend Pro plan.
Inputs: domain (required).
check_typoSuggest a fix for a mistyped emailARead-onlyInspect
Spot a likely typo in an email's domain (like gmial.com) and suggest the correct one, so you don't lose contacts to misspelled addresses. No credit used. Available on the Qualisend Pro plan.
Inputs: email (required).
generate_dns_recordCreate an email-authentication DNS recordARead-onlyInspect
Create the exact DNS setting a domain needs so its email is trusted and harder to spoof - SPF, DMARC, BIMI, or MTA-STS. Returns the record to copy into DNS, with where to put it. No credit used. Available on the Qualisend Pro plan.
Inputs: type (required), domain (required), all, ip4, +10 more.
get_credit_balanceGet credit balanceARead-onlyInspect
Return the number of verification credits available in your Qualisend workspace.
Inputs: no named parameters.
get_verificationGet a verification resultARead-onlyInspect
Look up the status and result of a verification you started, by job_id (returned from verify_email/verify_emails). For a single check it returns the final verdict once the mailbox probe completes; for a batch it returns progress + a result-mix summary.
Inputs: job_id (required).
lookup_smtp_codeExplain a mail-server error codeARead-onlyInspect
Explain a mail-server reply/error code (like 550 or 5.1.1) in plain English, and say whether it's a temporary hiccup or a permanent failure. No credit used. Available on the Qualisend Pro plan.
Inputs: code (required).
verify_emailVerify an email addressAInspect
Verify a single email address - syntax, domain/MX, disposable + role detection, typo suggestion, and mailbox reachability. Returns a deliverability verdict (deliverable / risky / undeliverable / unknown). Consumes 1 credit.
Inputs: email (required).
verify_emailsVerify a batch of email addressesAInspect
Verify up to 50 email addresses at once and get a deliverability verdict for each, synchronously. Consumes 1 credit per address. For larger lists (up to 1000), use verify_list.
Inputs: emails (required).
verify_listVerify a large list of email addressesAInspect
Verify a large list of up to 1000 email addresses. This runs ASYNCHRONOUSLY: it creates ONE bulk job, returns a job_id immediately, and the mailbox probes run in the background. Poll get_verification with the job_id for progress and a result summary (counts by verdict). Consumes 1 credit per address. For lists larger than 1000, use the Qualisend dashboard or bulk API.
Inputs: emails (required).
