Sending over 413+ million emails per month
Dead Simple Webhooks
Parse & process our webhook callbacks with ease. Email event information alongwith the email message for which event occurred is sent back. Super simple to integrate this data with your custom application or CRM.
Corelate Data Smartly
You can pass custom headers while sending emails using our Email Send API call. These headers are returned back in webhook call. They can be used to co-relate data in your application - what event happened when to whom for which campaign. Especially useful if you are building a webapp with email integrated in it or are an ESP.
Retry for 24 hours
In case of failure, we retry sending webhooks once every hour for next 24 hours. You dont have to worry about losing data due to failure in webhoook processing. Also we retain event log data for 90 days and more.
Custom Event. Custom Endpoint.
You can create multiple webhook endpoints for specific event processing. You can also pass the same email event to multiple applications or endpoints of yours.

Simple email sending & validation API, powerful analytics, smart alerting system and power deliverability optimisation tools make SendPost standout as the most forward thinking email API service.
