Sending email through an API is only half the job. The other half is knowing what happened next, and letting your software respond. For businesses and developers in Antigua and Barbuda, where many recipients are overseas and a missed message can mean a missed booking, that feedback loop matters.
Three ways to get the data
1. The Mailpro dashboard
Every message sent through the API appears in your account’s reports, with real-time statistics on delivery, bounces, opens and clicks. Good for managers who want an overview without touching code.
2. Status queries
Your application can ask the API for the delivery status of a transactional email. Useful for support tools: a staff member looks up a guest and sees whether their confirmation was delivered.
3. Webhooks
Mailpro can push events to your system as they happen. See the three types of Mailpro webhooks. Your code can then act immediately.
What to do with the data
| Event | Automatic response | Island example |
|---|---|---|
| Hard bounce | Flag the contact and try another channel. | A tour operator texts the guest’s +1 number when the confirmation email bounces. |
| Soft bounce | Wait for retries, then alert staff if still failing. | A villa manager’s system warns the team 24 hours before arrival. |
| Delivered, not opened | Send a reminder or SMS before a deadline. | A CIP agent’s portal reminds a client that documents are waiting. |
| Click | Update the CRM record or trigger a follow-up. | A charter broker notes interest in a Sailing Week package. |
| Unsubscribe or complaint | Stop marketing messages at once. | A retailer’s loyalty app updates the customer’s preferences. |
Metrics worth tracking over time
- Delivery rate by message type: confirmations, receipts and alerts should be close to all delivered. A drop usually points to authentication or address-quality issues.
- Bounce rate by source: addresses taken over the phone or on paper bounce more than those typed by customers online.
- Time to delivery: important for login codes and time-sensitive alerts.
- Volume by season: tourism traffic peaks from December to April and around the April regattas and Carnival. Plan capacity and monitoring accordingly.
Build a simple monitoring routine
You do not need a data team to use API statistics well. A practical routine for a small Antiguan business or agency:
- Daily: an automatic alert if hard bounces on confirmations pass a threshold you set, for example a handful in one day.
- Weekly: a glance at delivery and complaint rates by message type.
- Before each high season: a check that DNS authentication is intact, API keys are current and webhook endpoints respond.
- After an outage or storm: a review of queued and failed messages, and a resend of anything time-sensitive that did not go out.
Agencies that manage several clients on the islands can use separate API keys per client, so each business’s figures stay distinct.
Handle event data responsibly
Webhook payloads and logs include email addresses and activity data, which are personal data under Antigua and Barbuda’s Data Protection Act, 2013. Secure your webhook endpoint with HTTPS, restrict access, and delete logs you no longer need (the retention principle in section 9). Mailpro keeps its own copy on Swiss infrastructure, outside US jurisdiction.
