以纯文本形式发送的动态 sendgrid 模板

Question

I'm sending email through sendgrid, but when I receive the email, the email is in plain text format, and I would like to send it in html format. The variable data is the data I pass to sgMail.send.

module.exports = {
data: {
    to: '',
    from: '',
    subject: '',
    text: '',
    templateId: '',
    dynamic_template_data: {
        value_precip: undefined,
        value_humidity: undefined,
        value_windSpeed: undefined,
        value_condition: undefined,
        value_activiti: undefined
    }
},

set: function(to, from, subject, text, templateId, params) {
    this.data.to = to
    this.data.from = from
    this.data.subject = subject
    this.data.text = text
    this.data.templateId = templateId,
    this.data.dynamic_template_data.value_precipitation = params.value_precipitation
    this.data.dynamic_template_data.value_humidity = params.value_humidity
    this.data.dynamic_template_data.value_windSpeed = params.value_windy
    this.data.dynamic_template_data.value_condition = params.value_condition
    this.data.dynamic_template_data.value_activiti = params.value_activiti

},
    send: function() {
    try {
        sgMail.send(this.data)
    } catch (error) {
        console.log(error)
    }

   }
}

I don't know what may be causing this problem, if anyone can help me I would be grateful!

Answer 1

It looks like SendGrid uses html attribute to decide if the content type should be html even though they ignore the content. So, just include that attribute in the payload. Seems weird, but it worked for me.

PS: I didn't try it with JavaScript, I'm using Python.

Answer 2

It's simple, just remove the text .

As mentioned by a contributor of SendGrid. Read more

Given that dynamic templates contain both HTML and plain text content, text should not be passed when using a dynamic template.
