but mail goes spam folder.how send mail goes inbox.please guys me out this,i spend lot of time on it.

which folder email goes depends on domain & ipaddress email coming , email service provider. if domain/ip trusted service provider not spammed. also, after setting few emails "not spam" domain, email service no longer spam emails
