Sigmail

什么是 Sigmail？

Most email signatures are dead space. Sigmail turns them into trackable, animated funnels. We've run these across cold outbound campaigns and the results have been insane. One client saw 2x clicks to opens. Others are consistently hitting 40% click-to-open rates. Open rates held at 40-60% with zero deliverability impact. The signatures are lightweight, work across Gmail, Outlook, and any SMTP-based platform, and every link is tracked. Your emails are already being sent. Make them work harder.
