related to #1047

@kristoferlund I couldnt test it because we need to verify our domain https://docs.sendgrid.com/for-developers/sending-email/sender-identity

And also I think it's better to manage templates ourselves with creating some HTMLs it can be easier to get to know their services and temlates

@mohammadranjbarz I believe we already have verified domain.

Could you tell me more? What are the benefits of managing the templates in the code? Or perhaps, what are the drawbacks of using SendGrid templates? The big benefit is that we can give Justina or Ahmad or a designer the access to sendgrid and allow them to modify templates without us having to rebuild the code.

Final comment. We should follow the Nest.js design patterns and build the email sender service as a real service. Now you have constructed it as a utility function.
