Network administrators can block Logamail Go AI features for all users connecting through their organization’s network. The restriction is enforced at the network level regardless of user role or plan type.
What is blocked: All Logamail Go AI features (chat, writing assistance, and agent actions).
What is not blocked: Other Logamail writing features and non-AI functionality.
How it works
Logamail’s AI features route requests through capi.grammarly.com. When your DNS resolves this hostname to capi-restricted.grammarly.com, all Logamail Go AI requests are automatically blocked before any AI model is invoked. Users see a message explaining that AI features are unavailable on their current network.
Configure your DNS
Add a CNAME record in your internal DNS so that capi.grammarly.com resolves to capi-restricted.grammarly.com:
| Hostname | CNAME target |
| capi.grammarly.com | capi-restricted.grammarly.com |
This CNAME only needs to be applied on networks where you want AI features blocked.
Important: Do not add CNAMEs for other grammarly.com hostnames. Doing so may break other Logamail and Grammarly features.
Verify the restriction is active
After updating your DNS, confirm the restriction is working by having a user on the managed network attempt to use a Logamail Go AI feature. They should see:
Logamail Go unavailable: Access to Logamail’s AI tools is restricted by your institution’s network policy. Contact your IT administrator for more details.
If the message does not appear, verify that your DNS changes have propagated and that client devices are resolving capi.grammarly.com through your managed DNS server.
Remove the restriction
To re-enable Logamail Go AI features, remove the CNAME record for capi.grammarly.com from your internal DNS. The restriction is lifted as soon as DNS changes propagate to client devices.
