template: is an incomplete or empty template

I have a following piece of code in which i am trying to send an email using gopkg.in/gomail.v2. I am perfectly able to send the email when the email template is placed in the root directory of the project like this

./
    main.go
    template.html



// Info defines
type Info struct {
    Age  int
    Name string
}

func (i Info) sendMail() {
    fp := filepath.Join("template.html")

    t := template.New(fp)

    var err error
    t, err = t.ParseFiles(fp)
    if err != nil {
        log.Println(err)
    }

    var tpl bytes.Buffer
    if err := t.Execute(&tpl, i); err != nil {
        log.Println(err)
    }

    result := tpl.String()
    // ... email sending logic
}

func main() {
    info := &Info{
        Name: "name 1",
        Age:  20,
    }

    info.sendMail()
}

but when i change the template directory to emails/template.html and change the filepath to
fp := filepath.Join("emails", "template.html")
then I get the error from t.Execute()
template: "emails/template.html" is an incomplete or empty template

I have also tried fp, _ := filepath.Abs("emails/template.html") but got error

template: "/mnt/data/go/test/emails/template.html" is an incomplete or empty template the path mentioned is correct though.

I changed 

if err := t.Execute(&tpl, i); err != nil {
        log.Println(err)
    }

to 


if err := t2.ExecuteTemplate(&tpl, "template.html", i); err != nil {
        log.Println(err)
    }

and it worked

If I want to use t.Execute(&tpl, i) instead, then I have to specify the templates name as filename while creating the template

t := template.New("template.html")
