Why can’t I see Create in ChatGPT?

Custom apps depend on developer-mode access and workspace policy. Check the official setup guide below or ask your workspace administrator. You can also run a free domain check on the MailVakt website.

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.

Set up MailVakt in ChatGPT

Manual setup requires ChatGPT on the web with developer-mode access. Availability depends on your plan and workspace permissions; Business and Enterprise/Edu have full MCP support, while Pro has read/fetch support.

Enable developer mode in Settings → Apps → Advanced settings. In a managed workspace, your administrator may need to enable access or create the app.
In Apps, choose Create. Name the app MailVakt, paste the server URL below, and choose OAuth for account-linked features. Scan the tools and finish creating the app.
Start a conversation and add MailVakt from the apps menu. Ask it to check your domain and review any tool confirmation before continuing.
