Emails

How Nova sends emails

Unlike many areas in Nova where we leverage built-in CodeIgniter libraries, for email we use a custom library implementing SwiftMailer for sending all emails from Nova. We've built this in such a way that it should mirror the way that CodeIgniter handles email.

When Nova needs to send an email, the controller where that page lives will have a method called _email that handles all of the email situations for that controller.

Configuring emails from Nova

Nova and CodeIgniter provide a wealth of configuration options for how email is handled. You'll find all of the available configuration options in either Nova's System/Email tab of Site Settings or in the email config file found in the application/config directory. We've provided sensible defaults for emails, but your specific server and situation may dictate changes.

Changing the files used for emails

You might be surprised to find out that Nova treats emails almost identically to how it treats pages in the system. That means there's a view file that's used to structure and lay out the emails that are sent to players. This also means you can use seamless substitution to change the structure and layout of the emails.

Email issues

Over the last couple of years, email has become a significant pain point for more and more Nova games. We've heard about tons of people dealing with a whole host of email issues:

• "No one gets emails sent by Nova"
• "Some users get the emails sent by Nova, but others don't"
• "Some emails from Nova take hours to arrive"
• "I get an error when Nova tries to send emails"

By default, Nova uses PHP's mail() function for sending all mail. When the system was originally built, this was a reliable way of handling email. Over time and with the drastic rise in spam, more and more email service providers are cracking down on the ways that email has been sent from PHP applications. As a result, people have started to see situations where email isn't being properly delivered. So how do we fix these issues?

Third-party email service providers

The answer we've begun advocating is using a third-party email service provider. These are companies that offer to handle the sending of emails (also known as transactional emails) from a system like Nova to whatever recipients are on the email. We highly encourage users to use a third-party email service provider, and here's why:

1. They specialize in sending emails
2. They will increase your deliverability rate, often dramatically
3. Your emails are less likely to be labeled as “spam” and/or blocked completely (quite common)

Who's out there?

It can be a little daunting to step into the world of third-party email service providers, so here's a little primer on who's out there, ranging from completely free services to some that charge you monthly for the number of emails you send.

• SendGrid
• Mailgun
• Postmark
• SparkPost
• MailChimp
• Amazon SES
• SendPulse
• MailJet
• SendinBlue SMTP
• ElasticEmail

Any of the above SMTP services will work in Nova. If you're having issues today with emails not being delivered, you can get up and running in short order by signing up for one of the above services and plugging in the details in your email config file in Nova.

Using SMTP in Nova

In order to get Nova working with your SMTP service of choice, you simply need to update the application/config/email.php config file with the information you got from the service when you signed up:

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'http://smtp.example.com';
$config['smtp_user'] = 'username';
$config['smtp_pass'] = 'password';
$config['smtp_port'] = 25;

Save the file and upload it back to your server and you should be all set!

You can run a test by using the contact form to send something to yourself. If everything is working, you should get the contact page email like normal. If you don't get the email, you may need to use the SMTP service's dashboard to figure out if the email got to the service. (This goes back to what we talked about earlier about some services requiring additional setup in order to get it working properly.)

Not interested in third-party email service providers?

If you don't want to pull the trigger on a third-party email service provider, there are other methods you can try that have seen limited success:

• Under Site Settings on your Nova site, click on the System/Email tab. Scroll down to the bottom of the page and input an email associated with your domain as the "Default Email Address." For example, if you run a game at the domain uss-enterprise.com, you'd enter the email nova@uss-enterprise.com. (You may need to sign in to your hosting account to create a matching email address for this solution to work properly.)
• If you have the ability, try refreshing your DKIM/SPF records. If you don't know what that means, or if you don't have the ability, contact your web host. (This solves an issue where Google won't deliver your site's emails.)
• If your Nova sends hundreds of emails, your server might have a sending limit that blocks some emails from being delivered. Remember, every time you publish a post Nova has to send an email to each user on your site, not only one email. Either contact your web host and ask them to increase the limit or upgrade to a hosting plan with a higher sending limit.
