Website Building
#1

i builded my site, parked a domain and set on wordpress an email address to be notify for posting comments.
no emails arrived. my plan is a free plan hosting and i have 50 month mails to send/receive.
what’s my mail server? or how to receive or send emails?
thankz.

Hit general settings on 000webhost.com and enable SENDMAIL

No mail server - you’ve got 50 PHP SENDMAIL a month

You’ve got email forwarders you can setup within your control panel.

So if you get 50 comments on your site and you’ve got the comments > email enabled once you hit that your account MAY be suspended; better off without it surely and just checking WordPress daily?
