When a player in a gaming account says the verification email never came, or a client of a Sliema accounting firm says they did not receive an invoice, you need an answer in seconds. Mailpro’s SMTP statistics give you message-level visibility, so support teams can check what happened instead of guessing.
What you can see
| Data point | Typical use |
|---|---|
| Accepted / delivered | Confirm the receiving server took the message |
| Hard bounce | Invalid address; fix it in your application |
| Soft bounce | Temporary issue such as a full mailbox; retry automatically |
| Opens and clicks | Measure engagement with receipts or onboarding emails |
| Timestamps and recipient | Answer “when did it go?” support questions |
See SMTP server statistics and SMTP message tracking for the full list.
Proof of delivery
For regulated Maltese businesses, being able to show that a notice was sent and accepted can matter in a dispute. Delivery logs are not a legal guarantee that someone read a message, but they are strong evidence it was sent and received by their provider. Our article on proving invoice delivery with SMTP logs explains how accounting teams use them.
Reading patterns
Bounce clusters
A spike in bounces to one domain may mean that provider is filtering you. Check your SPF, DKIM and DMARC and review the common SMTP errors.
Seasonal volume
Tourism-driven systems send far more in summer. Watch whether delivery times stay stable as volumes climb in July and August, and consider a dedicated IP if you send heavily year-round.
Engagement on transactional mail
Low open rates on critical emails, such as password resets, may point to spam-folder placement rather than disinterest.
A support workflow that uses the logs
- A customer says they did not receive an email.
- Support searches the recipient address in the SMTP logs.
- If delivered, support asks the customer to check spam or promotions folders, and notes the timestamp.
- If bounced, support confirms the correct address and resends.
- If never sent, the issue is in the application, and support escalates to developers.
This routine turns a vague complaint into a two-minute check, which matters for high-volume Maltese platforms whose customers are spread across many countries.
Privacy of logs
Logs contain personal data such as email addresses and subjects. Under GDPR you should retain them only as long as needed. Mailpro stores them on private Swiss infrastructure outside US jurisdiction, and Switzerland’s EU adequacy decision means Maltese controllers need no extra transfer mechanism.
Webhooks for your own systems
If you want delivery events inside your own platform, set up a webhook to receive them in real time.
