reply_to has no effect about sendgrid-ruby

[coderdave]

Update: I figured it out. I had my yahoo address set up in my gmail settings under "Send mail as"! So gmail was seeing that and used my gmail account instead.

Thanks for the help.

Hello @coderdave,

Could you please provide us with a code snippet so we can try to reproduce?

Also, this library will be replaced by the new version in a few weeks, you can check it out here: https://github.com/sendgrid/sendgrid-ruby/tree/v3beta

With Best Regards,

Elmer

I'm just setting up a basic hash. I would like to send from [email protected] but let them "reply_to" a different address, but it doesn't work. (Also the from_name isn't work either)

def send_it
  # send from [email protected] if it's coming from a yahoo.com account :(
  from = self.from.include?("@yahoo.com") ? "[email protected]" : self.from
  email = {
    from: from,
    from_name: self.from_name, # sendgrid isn't using the name set here, it uses the from email address
    reply_to: self.from, # no affect
    to: self.to.split(",").uniq,
    bcc: self.bcc.present? ? self.bcc.split(",").uniq : nil,
    subject: self.subject,
    text: strip_tags(self.message),
    html: self.message
  }

  MailerJob.new.async.perform("SendgridMailer", nil, email)
end

Hello @coderdave,

Thanks for the additional information.

Where are you setting up the SendGrid::Mail object? In the MailerJob? If so, can I take a look at that code?

Thanks!

Elmer

  sendgrid = SendGrid::Client.new do |c|
    c.api_key = ENV["SENDGRID_APIKEY"]
  end
  email = arg
  sendgrid.send email

[thinkingserious]

email needs to be a SendGrid::Mail object. Please see: https://github.com/sendgrid/sendgrid-ruby#usage

[coderdave]

Ah, ok, I'll try that. Thanks.

[thinkingserious]

Thanks! Please let us know how it goes.

I finally got around to upgrading to v3. When I tested using reply_to, it still doesn't work.

mail.reply_to = SendGrid::Email.new(email: '[email protected]')

I get the email (to my gmail account) which is fine (and the custom name works) but when I try to reply to the email, it doesn't respect the reply_to I set up. It uses the regular reply email address that I used.

Is there something else I need to set?

@coderdave,

Before you make the call to API, could you please provide the output of:
puts JSON.pretty_generate(mail.to_json)

[coderdave]

[43] pry(main)> puts JSON.pretty_generate(mail.to_json)

{
  "from": {
    "email": "[email protected]",
    "name": "bing bong berry"
  },
  "subject": "hopefully can reply to",
  "personalizations": [
    {
      "to": [
        {
          "email": "[email protected]"
        }
      ]
    }
  ],
  "content": [
    {
      "type": "text/plain",
      "value": "Hello, Email!"
    }
  ],
  "reply_to": {
    "email": "[email protected]",
    "name": "bing bong berry"
  }
}

[thinkingserious]

Please try putting that payload in a file named post.json

and run the following (after substituting your API key):

curl -X "POST" "https://api.sendgrid.com/v3/mail/send" \
        -H "Authorization: Bearer $SENDGRID_API_KEY"  \
        -H "Content-Type: application/json" \
        -d @post.json

Same effect, email went through but it replies to "[email protected]"

[thinkingserious]

Hmm, I can not reproduce the error with Gmail as the client. Do you mind sharing the raw headers of the email you receive in Gmail?

[coderdave]

Ok, I see what's going on. It looks like the reply-to is being set but unfortunately, gmail doesn't respect it. That's too bad. Are there any workarounds for that?

And it's strange that when I reply, it replies to my gmail account, not the [email protected] one.

Thanks for following up with your solution!
