## Tools (as reported by the server, not verified)

- `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
- `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
- `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:
