Who this is for: tool vendors, white-label and fulfillment providers, and agency-to-agency partnerships.

Before you send: agencies are the toughest crowd you can email because they run cold email themselves, so reference something real about the shop and skip the template. Run copy through the Spam Checker, verify, and keep CAN-SPAM basics on every send.
