Технические названия из tools/list. Нужны только разработчикам.

verify_emailVerify 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.
verify_emailsVerify 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.
verify_listVerify 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.
get_credit_balanceReturn the number of verification credits available in your Qualisend workspace.
get_verificationLook 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.
check_domainCheck 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.
generate_dns_recordCreate 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.
analyze_email_headerRead 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.
check_disposableTell 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.
check_typoSpot 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.
lookup_smtp_codeExplain 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.
check_blacklistCheck 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.
