Transactional Emails using APIs
User Management resources
Depending on the invoked method, user management resources may require different credentials and authentication methods.
| Authentication type | References | Description |
|---|---|---|
| OAuth 2 | Authenticating with OAuth v2 | Standard OAuth 2 with access and refresh tokens. In the request you must add the following header: Authorization: Bearer {access_token}
Note: OAuth 2 requires the MailUp account credentials, not SMTP+ username and password |
| SMTP+ credentials in the request body | SMTP relay service | SMTP+ username and password must be included in each request through the "User" parameter inside the request body. "User":{"Username":"YourSmtpPlusUsername","Secret":"YourSmtpPlusPassword"}
An error may be returned when the SMTP+ user is blocked. In this case you could use the "ListUserInfo" method to get more details about that user. For example, there could be a billing issue. |
Create a SMTP+ user
To access resources and to use the methods, you must have an active account with an enabled SMTP+ user (SMTP+ users have the "sNNNNN_NN" name format). You can create SMTP+ accounts and retrieve their credentials:
- from within the MailUp platform. See: SMTP Settings
- calling a REST API endpoint
In this page we explain how to create a SMTP+ account using the REST API endpoint.

Messages
This section includes the methods that can be used to send transactional emails.
Use SendMessage when you need to specify a completely different content for each message, while you can use SendTemplate - and use merge tags - if you want to pick the body of an existing content and simply customize some of its parts.
The two methods provide the same level of performance: pick the one that better fits your needs.
Using a reply-to address different from the sender address
The use of a reply-to address different from the FROM email address must be enabled by MailUp. If you need this, please contact our support team by writing an email to support@mailup.com.
SendMessage
| Description | This method allows sending of a transactional message to multiple recipients. This method is not intended for bulk mailings. The message content is passed as input with HTML code or plain text. The message may also include attachments and embedded images. |
|---|---|
| Authentication | SMTP+ credentials in the request body |
| HTTP Method | POST |
| URL | https://send.mailup.com/API/v2.0/messages/sendmessage |
| Reference | |
| JSON request (example) | |
| JSON response (example) | Example of a successful response:{"Status":"done",Example of error: {"Status":"error", |
SendTemplate
| Description | This method allows sending of a transactional message to multiple recipients, taking advantage of placeholders to customize content. This method is not intended for bulk mailings. The message content (both HTML body and plain text) is obtained by specifying the unique ID of a message previously created and stored in the MailUp admin console. The message may also include attachments and embedded images. Only lowercase placeholders must be used in the referenced messages. If you use capital letters (e.g. "Dear [FirstName]", the text is not replaced. If you edit an email message already sent, wait 15 minutes before sending out the modified message. This time is needed to update the cache |
