It wasn’t until an angry client called to ask why, after multiple times reaching out, the company refused to respond, that the landscape architecture company realized something was wrong. After some investigating, the company found that their IP address had been blacklisted. Another website on their shared server was sending out spam, resulting in their IP being reported. Their website company was successful in getting the landscape architect’s website removed from the blacklists, but only two days later, their IP was blacklisted again, causing them to miss emails. They were able to recover some, but not all of the estimated 43 leads they had missed over the course of almost two months of being on the blacklists. This is the origin of the name 43Leads.
