About Qualisend
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.
