Send an email

To send an email, send a POST request to:

https://api.sendpulse.com/smtp/emails

Request parameters:

Email array parameters:

Example of sending a custom template:

{
  "email": {
    "html": "PHA+RXhhbXBsZSB0ZXh0PC9wPg==",
    "text": "Example text",
    "subject": "Example subject",
    "from": {
      "name": "Example name",
      "email": "sender@example.com"
    },
    "to": [
      {
        "name": "Recipient1 name",
        "email": "recipient1@example.com"
      }
    ]
  }
}

Example of sending a system template with custom variables:

{
  "email": {
    "subject": "Test",
    "template": {
      "id": 123456,
      "variables": {
        "name": "George",
        "code": "123456"
      }
    },
    "from": {
      "name": "Mike",
      "email": "mike.johnson@domain.com"
    },
    "to": [
      {
        "email": "recipient1@example.com",
        "name": "George"
      }
    ]
  }
}

In this example, a template parameter is used instead of html and text parameters.

Example of sending email copies:

{
  "email": {
    "html":"dGVzdCBBUEk=",
    "text": "text",
    "subject": "subject",
    "from": {
      "name": "test",
      "email": "test@test.com"
    },
    "to": [
      {
        "name": "recipient 1",
        "email": "recipient1@test.com"
      }
    ],
    "cc":[
      {
         "name":"recipient 2",
         "email":"recipient2@test.com" 
      }
    ],
    "bcc":[
      {
         "name":"recipient 3",
         "email":"recipient3@test.com" 
      }
    ]
  }
}

Example of sending an email with attachments:

{
  "email": {
    "html": "PHA+RXhhbXBsZSB0ZXh0PC9wPg==",
    "text": "Example text b",
    "subject": "Example subject b",
    "from": {
      "name": "Example name",
      "email": "sender@example.com"
    },
    "to": [
      {
        "name": "Recipient1 name",
        "email": "recipient1@example.com"
      }
    ],
    "attachments":{
        "file1.txt":"file1 text content",
        "file2.txt":"file2 text content"
    }
  }
}

Example of sending an email with attachments_binary:

{
  "email": {
    "html": "PHA+RXhhbXBsZSB0ZXh0PC9wPg==",
    "text": "Example text b",
    "subject": "Example subject b",
    "from": {
      "name": "Example name",
      "email": "sender@example.com"
    },
    "to": [
      {
        "name": "Recipient1 name",
        "email": "recipient1@example.com"
      }
    ],
    "attachments_binary":{
        "file1.txt":"bXkgdGV4dA==",
        "file2.txt":"bXkgdGV4dA=="
