Writing CSS rules for generating HTML code when sending emails through the command line in Go

Question

Writing CSS rules for generating HTML code when sending emails through the command line in Go

When trying to compose HTML with CSS for email delivery using Go command line execution, errors related to CSS properties are popping up. For instance, it's showing "not found" error in the terminal for properties like background: rgb(255, 255, 255) or padding.

The code snippet that illustrates some of the HTML and CSS properties being utilized is as follows:

<div style="margin: 0; padding: 0; background: #ffffff; font-family: Montserrat, sans-serif; font-size: 16px; color: #313131">

Additionally, the method used for sending emails via the command line is provided below:

A situation arises where a customer can configure their own template in an editor, potentially introducing various CSS properties. This scenario may lead to errors due to these random properties.

In light of the aforementioned errors, one query stands out - does the command line require specific CSS rules for successful email transmission?

Update:

The error output received while executing the EmailSend() function is displayed below:

sh: 
padding: not found
sh: 
background: not found

Answer №1

As previously mentioned by Adrian in the comments above, I used the go command itself to parse html and css properties. Here is a simplified solution for sending emails through the command line with html and css.

func (request *EmailRequest) EmailSend(notificationTemplateData interface{}) (bool, error) {    
    subject, errParse := ParseTemplate(request.EmailSubject, notificationTemplateData)
    body, errParse    := ParseTemplate(request.EmailBody, notificationTemplateData)
    if errParse != nil{
        return false, errParse
    }
    err := ExecuteMailCommand("mail -s \"$(echo \" "+subject+" \nMIME-version: 1.0;\nContent-Type: text/html;charset=\"UTF-8\";\n\")\"  "+request.EmailTo, body)
    if err != nil {
        return false, err
    }

    return true, nil
}

func ExecuteMailCommand(command string, body string) error {
    cmd := exec.Command("sh", "-c", command)
    cmd.Stdin = bytes.NewBufferString(body)

    stdout, err := cmd.CombinedOutput()
    if err != nil {
        fmt.Printf("%v\n", err)
        return err
    }

    fmt.Printf("%s\n", stdout)
    return nil
}

The function ParseTemplate remains unchanged in the code above.

Thank you!
