When following up an email given there's no response after the initial email, reply() goes to myself, given I'm the one who sent the last email.
So for example, client A sends email to client B. Client A runs script below and reply goes to client A, but it should go to client B as it's only following up since there was no initial reply from B. At least that's how it goes in Gmail interface. I want to send a follow up.
I could run a separate sendmail, but that'll start a new thread unless you can specify the in-reply-to header or the user has responded to the existing thread, which they have not in my case.
Example code:
message.reply("incapable of HTML", {
htmlBody: "<b>some HTML body text</b>",
replyTo: theirEmailAddress,
});
However, replyTo actually just specifies the reply-to part of the email being sent, so the response that we receive. It has nothing to do with the actual to field aka recipient.
If I do replyAll, then the header for the email is:
from: me@me.com
to: them@them.com
cc: me@me.com
So from that, I get a bunch of emails from myself. I tried specifying cc as none but that didn't change the cc field.
threads[0].replyAll("Just wanted to follow up and see if you got my last email.", {
htmlBody: followUpText,
cc: null,
});
How do I follow up an email, and send it to the original recipient of the last email?
