I am using Contact form 7 plugin for wordpress but all emails created from this plugin are spam for gmail. How Can I resolve ?
You use smtp login or you send emails with php mail ? This maybe a "problem" of your server.If on your server are hosted more websites and some of them send spam emails is possible the ip of your host to be blacklisted on gmail or something like that. Anouther problem can be the smtp login.If you use bad login details the email is possible to go to spam section on gmail. Let us know what config you use for wordpress.From what email you send emails ? Is a gmail account or is a email account from your domain ?
