• 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…

• 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…

• 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…

• check_disposable

• 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…
