Configuring your own email transport

Campaign Studio offers SparkPost (a best of breed email transport) to its users. Some companies may have an existing relationship with another provider, which is why you can bring your own.

To configure your own mail transport:

  1. Sign into your Campaign Studio Account.

  2. Navigate to Settings by clicking the gear in the upper right corner.


  3. Click Configuration > Email Settings.

  4. Under Mail Send Settings, select the Service to send mail through:

    Select a service to send emails through

    Campaign Studio offers the can send mail through the following services:

    • AmazonSES
    • Elastic Email
    • Gmail
    • Mailjet
    • Mandrill
    • Campaign Studio (Only selected if you’re leveraging Campaign Studio’s Transport)
    • Momentum
    • Other SMTP Server
    • Postmark
    • Sendgrid (either using an API key or SMTP credentials)
    • SparkPost
  5. If you’re selecting an integration which requires an API Key, enter the key into the displayed field, and then click Test connection.  You can send a test email, which goes to the default E-mail address to send mail from.


    If you select any of the other native integrations, you must enter the required information in the displayed fields. The required information may vary from service to service. Some may require the API Key, others may need a Username, Host, and Port.

Other SMTP Server

If you have an SMTP server you’d like to use (such as your own servers), and Campaign Studio doesn’t have a native integration, use Other SMTP Server.


This option requires the Host and Port for the Mail Server.  You must select the encryption type used by the SMTP Server (None, TLS or SSL) and the authentication mode used by the SMTP Server (None, Plain, Login or Cram-MD5). If you select an authentication mode other than None, more fields for the credentials will display for you to add the username and password for the selected mail service. Once you’ve configured the service, test the connection, and send a test email.
