Triage

Your Construction inbox, sorted the way you sort it

Kerna starts you with five categories built for this industry and hands them to you in your own language. Rename them, rewrite them, or add one of your own. Nothing is fixed and nothing is saved until you say so.

Frequently asked questions

Does Kerna connect to our project management software?

Not directly. Kerna works inside Gmail and Outlook. Extracted fields export to Google Sheets from Gmail or to Excel from Outlook, and in Outlook, Send to passes a checked form to Make, Zapier or Power Automate, where your automation takes it on.

Can site staff use it on a phone?

The Gmail add-on works in the Gmail mobile app on Android and iOS. Kerna for Outlook works in Outlook on the desktop and the web, not in the Outlook mobile apps.

Is it useful for a small contractor?

Yes. Starter is free for one mailbox, with no card.

Can the office and site teams share one mailbox?

In Outlook, on Business and Enterprise. Kerna shows who has each email and its status. It stores the status, never the email.
