Verify email addresses and clean lists to improve deliverability and sender reputation.
Список инструментов сервера (12)
Технические названия из tools/list. Нужны только разработчикам.
| verify_email | 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. |
| verify_emails | 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. |
| verify_list | 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. |
| get_credit_balance | Return the number of verification credits available in your Qualisend workspace. |
| get_verification | 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. |
| check_domain | 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. |
| generate_dns_record | 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. |
| analyze_email_header | 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. |
| check_disposable | 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. |
| check_typo | 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. |
| lookup_smtp_code | 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. |
| check_blacklist | 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. |
