Campaign Studio

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:

    Campaign Studio 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


    Instances within a Campaign Factory account can employ distinct email sending services. However, one instance can use only a single email sending service.

    Email send rate limits are determined by the email service configured.

    Campaign Studio now supports the Amazon SES API for email sending to enable SES users to send emails faster than the existing SMTP-only connection.

  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 are displayed for you to add the username and password for the selected mail service. After you configure the service, test the connection and send a test email.


Campaign Studio does not support emails on port 25 because of platform hosting restrictions. Therefore, you must use the port 465, 587, or 2525.
