Does this need a local Claude Desktop server?

No. MailVakt is a hosted remote connector. Add its URL through your Claude account; there is no local server or package to run.

Will MailVakt change my DNS or send email as me?

No. Domain checks read public DNS and return findings and suggested fixes. You make any DNS edits yourself. For an inbox test, you send a message to a temporary test address; MailVakt does not send it for you.

Does fixing these records guarantee inbox placement?

No. Authentication is one part of deliverability. Sender reputation, message content and recipient behavior also matter. MailVakt helps you find and address configuration problems.
