How to Configure Your Own ESP/Transport

Mautic offers SparkPost (a best of breed email transport) to its users.  However, we know that some companies may already have an existing relationship with another provider, which is why we make it easy for you to bring your own!  To get started, make sure you’re logged into your Mautic Account, and navigate over to Settings by clicking the gear in the upper right corner:

Next, you’ll click Configuration and then head into Email Settings and select the Service to send mail through via the drop down under Mail Send Settings:


Natively, Mautic offers the ability to send mail through the following services:

  • AmazonSES
  • Elastic Email
  • Gmail
  • Mailjet
  • Mandrill
  • Mautic (This would only be selected if you’re leveraging Mautic’s Transport)
  • Momentum
  • Other SMTP Server
  • Postmark
  • Sendgrid (either using an API key or SMTP credentials)
  • SparkPost

If you’re selecting one of our integrations that only requires an API Key, all you need to do is enter it into the field that appears, then click Test connection, and you’re all set!  You can even send a test email, which will go to the default E-mail address to send mail from:


If you select any of the other native integrations, you’ll need to enter the required information in the fields that appear – the required information may vary from service to service.  Some may only require the API Key, others may need a Username, Host and/or Port.


Other SMTP Server

You may have noticed Other SMTP Server as an option.  This is for any SMTP Server that you’d like to use, in case Mautic does not currently have a native integration for what you’re using (maybe your own servers):

This option requires the Host for the Mail Server and the Port for the Mail Server.  You’ll need to select the encryption type used by the SMTP Server (None, TLS or SSL) as well as the authentication mode used by the SMTP Server (None, Plain, Login or Cram-MD5).  If you select an authentication mode other than None, additional fields for the credentials will appear below for you to add the Username and password for the selected mail service.

Once you’ve configured this service, test the connection, send a test email, and you’ll be good to go!
