The CSV importer can email you the results of the CSV import. This is useful for cron jobs.

In your .env.example file or using Docker environment variables, configure the CSV importer as follows:



Update the settings to match your email configuration. The first thing you'll want to update is the MAIL_MAILER. The mail mailer indicates the system that is used for mailing. The CSV importer supports the following mail systems: smtp, sendmail, mailgun, mandrill, sparkpost and log.

Make sure that you always change the MAIL_FROM address. If this is wrong, mail might never work!


The default value will store messages in your log files instead of sending them.


SMTP is the de-facto standard for sending email. If you want to use GMail or Outlook as mail system, set the mailer to smtp. Make sure you change the host, port and credentials and of course, MAIL_ENCRYPTION must be null, ssl or tls, depending on your provider.


Uses the built-in sendmail configuration. If you choose this, you can leave the other values alone.


Mailgun is an API that can send emails. Their service allows for 10,000 free messages each month.

To configure these, fill in the MAILGUN_DOMAIN, MAILGUN_SECRET, and MAILGUN_ENDPOINT values in your .env file. The MAILGUN_DOMAIN is the domain you've verified with Mailgun, the MAILGUN_SECRET is your Mailgun API key, and the MAILGUN_ENDPOINT is the Mailgun API endpoint,, if you are sending email from Mailgun's U.S. infrastructure, or, from their EU infrastructure. Make sure MAIL_FROM is set to an email address that is from your Mailgun's verfied domain.


Mandrill is a paid service by MailChimp. Find the MANDRILL_SECRET and fill it in. That should be enough to enable email over Mandrill. Note that I haven't actually tested this.


Sparkpost is another paid service. Find the SPARKPOST_SECRET to configure sending email over Sparkpost. Note that I haven't actually tested this.
