Dynamic Variables

Dynamic variables can be included in the campaign content.

For example:

Hello %%first_name%%,

Your email address is %%email%%.

<a href="%%unsubscribelink%%">Unsubscribe</a>

Common variables supported by the campaign system include:

Variable	Description
`%%email%%`	Subscriber email
`%%first_name%%`	First name
`%%last_name%%`	Last name
`%%city%%`	City
`%%country%%`	Country
`%%post_code%%`	Postal code
`%%state%%`	State
`%%mobile%%`	Mobile
`%%phone%%`	Phone
`%%fax%%`	Fax
`%%title%%`	Title
`%%company%%`	Company
`%%create_date%%`	Subscriber creation date
`%%list_name%%`	List name
`%%list_id%%`	List ID
`%%email_id%%`	Email/subscriber ID
`%%message_id%%`	Message ID
`%%campaign_id%%`	Campaign ID
`%%from_name%%`	Sender name
`%%from_email%%`	Sender email
`%%today_date%%`	Current date

The campaign system also supports custom fields, Spin Tags, and Dynamic Content Tags where those features are enabled.

Unsubscribe Link

An unsubscribe link can be included in the HTML content.

Example:

<a href="%%unsubscribelink%%">Unsubscribe</a>

It is recommended that marketing campaigns include the appropriate unsubscribe link required for your use case and applicable requirements.

Campaign Links

URLs contained in campaign content are automatically detected when a campaign is created or updated.

For example:

<a href="https://example.com/special-offer">
    View Special Offer
</a>

The URL is associated with the campaign in the campaign links table.

GET /getCampaign also returns the detected links:

{
  "links": [
    "https://example.com/special-offer"
  ]
}

Both <a href=""> and <area href=""> links are detected.

HTML and Plain-Text Content

Each campaign contains two versions of the message.

HTML Version

Use:

email_content

Example:

<h1>Hello %%first_name%%</h1>

<p>Check out our latest offers.</p>

<a href="https://example.com/offers">
    View Offers
</a>

Plain-Text Version

Use:

text_content

Example:

Hello %%first_name%%,

Check out our latest offers:

https://example.com/offers

Providing both versions helps clients that cannot or do not display HTML email.

Campaign Groups

campaign_group can be used to organize campaigns.

For example:

Newsletter
Promotions
Transactional
Customers
Product Updates

Example:

curl -X POST \
"https://YOUR-DOMAIN/API-PATH/addCampaign" \
  -d "campaign_group=Promotions" \
  -d "campaign_label=Black Friday 2026" \
  -d "email_subject=Black Friday Special" \
  -d "email_content=<h1>Black Friday Special</h1>" \
  -d "text_content=Black Friday Special"

You can later retrieve campaigns belonging to a specific group:

GET /getCampaigns?campaign_group=Promotions

Typical Workflow

A common API workflow is:

1. Create Email Campaign
        ↓
POST /addCampaign

2. Receive Campaign ID
        ↓
Campaign ID: 125

3. Schedule Campaign
        ↓
POST /scheduleCampaign

4. Supply Campaign ID
        ↓
email_campaign_id_fk[]=125

5. Select Lists or Segments
        ↓
list_id_fk[]=10
or
segment_id_fk[]=15

6. Select SMTP
        ↓
smtp_list[]=smtp-user

7. Campaign is scheduled for delivery

Creating an email campaign does not send it automatically.

The /addCampaign API creates the email content. Use the Schedule Campaign API to select recipients, SMTP accounts, sender information, tracking settings, and delivery time.

Error Responses

If a required parameter is missing, the API returns an error.

Example:

{
  "success": false,
  "message": "campaign_label is required"
}

Other possible errors include:

campaign_group is required
campaign_label is required
email_subject is required
email_content is required
text_content is required
campaign_id is required
Campaign not found or access denied
Campaign in Running State is not editable.
Campaign in Running State cannot be deleted.

Security and Account Access

Campaigns are restricted to the authenticated account.

A user cannot retrieve, modify, or delete an email campaign belonging to another account.

Always use the same authentication method required by the other API functions on your account.

Complete Example

Create the campaign:

curl -X POST \
"https://YOUR-DOMAIN/API-PATH/addCampaign" \
  -d "campaign_group=Newsletter" \
  -d "campaign_label=Weekly Newsletter" \
  -d "email_subject=This Week's News" \
  -d "email_content=<h1>Hello %%first_name%%</h1><p>Here is this week's news.</p><p><a href='https://example.com/news'>Read More</a></p><p><a href='%%unsubscribelink%%'>Unsubscribe</a></p>" \
  -d "text_content=Hello %%first_name%%. Here is this week's news. https://example.com/news"

The API returns the Campaign ID:

{
  "success": true,
  "Campaign ID": 125
}

Retrieve it:

GET /getCampaign?campaign_id=125

Update it:

curl -X POST \
"https://YOUR-DOMAIN/API-PATH/updateCampaign" \
  -d "campaign_id=125" \
  -d "email_subject=Updated: This Week's News"

When the campaign is ready, use its Campaign ID with the Schedule Campaign API:

email_campaign_id_fk[]=125
