Hello, i am using a online reservation booking plugin in my website (avlutfiyebozdogan.com.tr). When the customer books an appointment, emails need to be send both customer and administrator. I tried a few times and reached out the plugins support team. They see that there is nothing wrong with the plugin. Emails seem to be sending in email logging plugin (and I am using Brevo smtp ). I reached out my hosting provider, they checked and replied me that there is nothing wrong about hosting too. Like I mentioned before, emails seem to be sending but customer and administrator can not recieve any email. I checked spam folders also. Can you inform me about how to solve this?
