Transactional (API/SMTP)

Getting Started

This section will guide you through the essential setup steps required to start sending emails using our powerful infrastructure.

Account Access & Onboarding

Kasplo does not support open sign-ups. All clients are manually onboarded to ensure optimal setup and deliverability. Upon onboarding, you will receive your SMTP credentials and access to your client portal.

DNS Configuration

For successful email delivery and sender authentication, clients must configure the following DNS records:

• SPF (Sender Policy Framework): Authorizes Kasplo servers to send emails on behalf of your domain.

• DKIM (DomainKeys Identified Mail): Ensures email integrity and helps prevent spoofing by digitally signing messages.

• DMARC (Domain-based Message Authentication, Reporting & Conformance): Enforces policies on SPF/DKIM alignment and provides visibility through reports.

• Tracking Domain: Customizes and masks tracking links for better branding and improved deliverability.

You will receive all necessary DNS record values during onboarding. Please add them to your domain registrar’s DNS settings to activate sending.

Webhook Configuration

To receive real-time email events (such as opens, clicks, bounces, etc.), clients must provide a valid Event Notification URL.

Kasplo will post structured JSON payloads to this endpoint for all supported events.

Data Retention

Event logs and metadata are retained for 30 days by default. Extended data retention plans are available upon request.

Authentication Methods

Kasplo supports two methods of authentication:

SMTP Authentication:

• Set the SMTP Host: smtp.kasplo.com

• Decide on Encryption:

  • For no encryption, select Port 587.

  • For TLS encryption, select Port 2525.

• Enter the credentials provided post-onboarding.

• Save your configuration and test your connection.

API Authentication:

• Generate and manage your API keys from the Settings section in your client portal.

• Use the key as a Bearer token in the Authorization header for all API requests.

Once these steps are completed, you’re ready to start sending with Kasplo. For more advanced configurations and examples, explore the following sections in this documentation.
