Email never makes it to inbox

Hey lemosop; Try the solution offered here: https://elftest.net/contact-form-7-and-anti-spam/.

I’ve taken that from the bottom of this thread (and it worked for me): https://www.ads-software.com/support/topic/contact-form-7-not-sending-emails-no-confirmation-no-error?replies=18

I’ve had problems in the past where emails haven’t made it to some email addresses, but they do make it to say Gmail.

This in my case pointed to the messages being rejected as spam at the DNS level (nothing to do with the contact7 plugin, but the domain SPF settings).

Anyhow, sending via a separate email account using SMTP, such as a Gmail account always works for me. Try this: https://www.ads-software.com/extend/plugins/configure-smtp/
