Yes—if your email provider supports webhooks, event callbacks, or an event API.
What that usually means
Your provider can notify your backend about events like:
- Delivered
- Opened
- Clicked
- Bounced
- Deferred / delayed
- Spam complaint
- Unsubscribed
How it works
- You configure a webhook URL in your backend.
- Your email provider sends an HTTP POST to that URL when an event happens.
- Your backend receives the event and processes it.
Common provider terms
Different providers call this differently:
- Webhooks
- Event webhooks
- Message events
- Inbound/Outbound event callbacks
- Tracking webhooks
Things to check
- Whether your provider supports the specific event you want
- Whether delivery events are available for your plan
- How to verify webhook authenticity
- Retry behavior if your backend is down
- Whether events are near-real-time or delayed
Example setup
If your provider is something like SendGrid, Mailgun, Postmark, Amazon SES, SparkPost, etc., they typically support some form of event webhook.
If you want, tell me which email provider you use, and I can tell you exactly whether it supports delivery events and how to wire it up.
