The Red Hot Tool of the Week is a weekly email that features an online tool for small business owners. It can be a productivity app, statistics/metrics/analytics software, marketing tool, sales booster, customer service app, website add-on, collaboration tool, or anything that small business owners might use. We give it a test drive, and if it makes the cut, it gets featured as a Red Hot Tool. An easy-to-digest summary is sent out via email to subscribers.

The Red Hot Tool of the Week is a free service of the Bonfire — if you’re not yet receiving the Red Hot Tool emails, you can subscribe here. Small Business Bonfire members can access the complete list of featured tools in the Red Hot Tool archive (membership in our small business community is also free).
