QualisendVerify whether sales@acme.com is a real, deliverable email addressQualisendCheck if these emails are deliverable and flag the bad ones: jane@gmail.com, info@acme.com, test@notarealdomain123.comQualisendIs acme.com set up to reach the inbox? Check its SPF and DMARC

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.
