Verify and clean email lists

Integration details

Description

Qualisend verifies email addresses and cleans lists so your messages reach real inboxes and bounces stay low. Ask it to check a single address, a batch, or a whole list — you get a clear deliverable / risky / undeliverable / unknown verdict for each, with typo suggestions and disposable- and role-address detection. It runs the full check: syntax, domain and mail server (MX), disposable and role detection, catch-all, and a real mailbox (SMTP) check. Large lists run in the background and return a result summary you can review. On the Pro plan it also checks whether a sending domain is set up correctly (SPF/DMARC), generates the DNS records you need (SPF, DMARC, BIMI, MTA-STS), and analyzes raw email headers to diagnose deliverability. With the Blacklist Monitoring add-on it can check whether a domain or IP is on major blacklists. Each verification uses one Qualisend credit, and you connect your own Qualisend account.

Tools

12 tools agents can invoke

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.
analyze_email_header
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.
check_blacklist
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.
check_domain
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_disposable
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.
generate_dns_record
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.
lookup_smtp_code
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.
get_verification
Return the number of verification credits available in your Qualisend workspace.
get_credit_balance
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.
check_typo
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_emails
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.
verify_list
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_email
