Core Concepts

Contacts

Contacts are email recipients in your marketing system. Each contact has basic information (name, email, surname) and a subscription status. If double opt-in is enabled, new contacts start with a pending status and receive a confirmation email.

Segments

Segments group contacts based on specific criteria (email, name, subscription status, engagement metrics, etc.). Segments support complex filtering with operators like equals, contains, gte, lte, opened, clicked, etc.

Profiles

Sender profiles represent the email identity used to send campaigns. Each profile has basic information and is associated with your account.

Contact Groups

Groups are a way to organize contacts (deprecated in favor of segments).

Subscription Status

Contacts can have different subscription statuses that determine whether they receive emails. Status can be used as a filter when listing contacts.

Common Patterns

Create and Manage Contacts

# Create a new contact (direct)
curl -X POST "https://developers.hostinger.com/api/reach/v1/contacts" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "email": "[email protected]",
    "name": "John",
    "surname": "Doe",
    "phone": "+15551234567",
    "note": "Met at conference"
  }'

# Create a new contact (scoped to a specific sender profile)
curl -X POST "https://developers.hostinger.com/api/reach/v1/profiles/{profileUuid}/contacts" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "email": "[email protected]",
    "name": "John",
    "surname": "Doe"
  }'

# List contacts (paginated)
curl -X GET "https://developers.hostinger.com/api/reach/v1/contacts?page=1" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN"

# Filter contacts by subscription status
curl -X GET "https://developers.hostinger.com/api/reach/v1/contacts?subscription_status=active" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN"

# List contact groups
curl -X GET "https://developers.hostinger.com/api/reach/v1/contacts/groups" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN"

# Delete a contact
curl -X DELETE "https://developers.hostinger.com/api/reach/v1/contacts/{uuid}" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN"

Python SDK:

from hostinger_api import Hostinger

client = Hostinger(api_token="YOUR_API_TOKEN")

# List contacts
contacts = client.reach.contacts.list(page=1)
for contact in contacts:
    print(f"{contact.name} <{contact.email}>")

TypeScript SDK:

import { Hostinger } from "hostinger-api-sdk";

const client = new Hostinger({ apiToken: "YOUR_API_TOKEN" });

const contacts = await client.reach.contacts.list({ page: 1 });
for (const contact of contacts) {
  console.log(`${contact.name} <${contact.email}>`);
}

PHP SDK:

use Hostinger\Api\HostingerApi;

$client = new HostingerApi('YOUR_API_TOKEN');

$contacts = $client->reach->contacts->list(['page' => 1]);
foreach ($contacts as $contact) {
    echo "{$contact->name} <{$contact->email}>\n";
}

Work with Segments

# List all segments
curl -X GET "https://developers.hostinger.com/api/reach/v1/segmentation/segments" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN"

# Create a segment (e.g., engaged subscribers who opened emails)
curl -X POST "https://developers.hostinger.com/api/reach/v1/segmentation/segments" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Engaged Subscribers",
    "logic": "and",
    "conditions": [
      {
        "field": "subscription_status",
        "operator": "equals",
        "value": "active"
      },
      {
        "field": "email_engagement",
        "operator": "opened"
      }
    ]
  }'

# Get segment details
curl -X GET "https://developers.hostinger.com/api/reach/v1/segmentation/segments/{segmentUuid}" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN"

# List contacts in a segment (paginated)
curl -X GET "https://developers.hostinger.com/api/reach/v1/segmentation/segments/{segmentUuid}/contacts?page=1&per_page=50" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN"

Manage Profiles

# List all sender profiles
curl -X GET "https://developers.hostinger.com/api/reach/v1/profiles" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN"

Best Practices

Contact Management

• Use the direct POST /contacts endpoint for general contact creation; use POST /profiles/{profileUuid}/contacts when the contact must be tied to a specific sender profile
• Prefer segments over contact groups for organizing contacts — groups are legacy
• Enable double opt-in for compliance with email marketing regulations (GDPR, CAN-SPAM)
• Clean your contact list regularly by removing bounced and unsubscribed contacts

Segmentation

• Use and logic for narrow, precise targeting
• Use or logic for broader audience reach
• Combine engagement operators (opened, clicked) with time-based operators for re-engagement campaigns
• Create segments before campaigns to preview audience size

Profiles

• Verify sender profiles to improve deliverability
• Use consistent sender identity across campaigns

Troubleshooting

Contact Not Receiving Emails

• Check subscription status — contact may be unsubscribed or pending
• If double opt-in is enabled, contact must confirm their email first
• Verify the contact's email address is valid and not bouncing

Segment Returns No Contacts

• Verify conditions and operators are correct
• Check that logic field (and/or) matches your intent
• Ensure contacts exist that match all/any conditions

422 Validation Error on Contact Creation

• Missing required fields (email is required)
• Invalid email format
• Duplicate email address in the system
