Emails that I send arrive to "Promotions" tab

Hello! I configured email routing and I’m routing it to Gmail account. To have ability to send emails from my configured routed email, I added it in Gmail settings http://sharex.sdzkhel.ml:40115/gMdmQw70t7RxgSU/direct, but, for some reason, if I send someone an email, it will arrive in “Promotions” tab. How should I fix it? Thanks
