Email not getting through with Success message

Hello,

I’m using your plugin for a simple mail contact in a showcase website.

I’ve set up the plugin and the email is not getting through, I tried gmail.com and yopmail.com for the contact mail but none are working. I’m still getting a success message though. I’ve checked the spam folder as well and it’s just not there. Do you have any idea what it could be ?
