What Qualisend does in ChatGPT
The Qualisend plugin checks email addresses from inside ChatGPT. You give it one address, a few, or a whole list, and each gets a verdict: deliverable, risky, undeliverable or unknown. It also suggests fixes for typos and flags throwaway and role addresses like info@.
Each check covers syntax, the domain and its mail server, catch-all setups and a real mailbox test. Large lists run in the background and come back with a summary. It runs on your own Qualisend account, and every address it checks costs one credit.
On the Pro plan it can also check whether a sending domain has SPF and DMARC set up correctly, generate the DNS records you need, including SPF, DMARC, BIMI and MTA-STS, and read raw email headers to find delivery problems. There is also an optional add-on that watches whether your domain or IP address ends up on well-known spam blacklists.
