Contact
Email hello@loftlie.com. There is no contact form here on purpose — a form would mean storing your message on this server, and an email address does the same job without that.
Corrections
The most valuable thing you can send. Include the club and a link to the manufacturer’s page showing the correct figure, and it can be verified and fixed quickly. A correction without a source takes much longer to act on, because it has to be researched from scratch before anything changes.
Missing equipment
If a club, shaft or ball isn’t listed, say which one and where its specifications are published. New models are added continuously, but coverage of older equipment depends heavily on what manufacturers still have online.
Advertising
Enquiries about advertising or sponsorship are welcome at the same address. How the site is funded, and the limits placed on that, are set out on the about page.
