Certified mail is the most underrated, underutilized aspect of credit repair. Most credit repair companies don’t employ certified mail (read about 98% here). If it works so well then why don’t they use it? Money – plain and simple. Certified mail is very expensive and other credit repair companies would rather make a few extra bucks or try to undercut each others’ prices for the cheapest service rather than use certified mail and get better results for the client!
