its sounding like something has fallen over somewhere… Which is weird because my tests all worked ok prior to adding the 100ish users (I just launched the website).
the contact us form is Contact Form 7… The other emails that aren’t working are being triggered by either WooCommerce or WordPress. I’ll do some testing to figure out what is causing the issue.
Do you know if there is a log somewhere to tell me what emails have been “sent” so I can confirm that the website has attempted to queue them?
