Sending sms notifications through my email using send SMTP mail message is not working

I’m trying to use SMTP mail message activity to send an SMS notification to my phone through my google gmail email. I see the message in gmail sent folder but I don’t receive any SMS on my phone. I have a t-mobile phone number. I use the following in the Reciever section / To filed: “”. In host section, I use port: 587, Server :“”.
