send email from a table

Hello, I am trying to send an email to the client from a table with the data of a work order, I use a gmail email, but the emails do not go out or arrive, if I check the spam tray they are not there either and I need it to be sent that email from the table, I go to the whitelisting and put the data and it tells me that gmail is already registered, I would like you to help me to see if I am doing something wrong.

Thanks a lot
