First time mass-emailing using Sendgrid with rails

I am running a rails app on heroku and would like to send an email to 160 users. This is the first time I am doing this so I would to very whether the method below will lead to a successful outcome.

Sendgrid is all sent up and I have a controller setup that executes the following:

@users = User.all
@users.each do |u|
  Email.send_email(p).deliver
end

I am assuming that since the number of recipients is relatively low I would be able to get by without using delayed_job or some other background processing.

SendGrid actually makes it easy to send out emails without having to use a background worker. You can do it using the X-SMTPAPI header and setting an array of email addresses in the to field. For example:

X-SMTPAPI: {
  to: ["[email protected]", "[email protected]", "[email protected]"]
}

In this example, each of these three emails will receive a separate copy of the email. No background workers, no complexity.

There's a gem called sendgrid that does a good job of adding some useful helpers to action mailer. Have a look at the "multiple recipients" section of the README

I would advise that you invest the time into some background processing, as this could potentially be a hit or miss, all depending on the emailing service.
