What I meant was your server logs, checking that the email is actually sending where it’s meant to, my issue was I assumed it was because I got the green success message but the message wasn’t being sent properly.
An easier way to tackle it is use this plugin, select the email you’re trying to use and run the test, you will then see if the server is sending ok > https://www.ads-software.com/plugins/wp-mail-smtp/
