That looks like a **phishing scam**, not a real DHL message.

Here’s why:

- **Suspicious link:** The domain is `dhl.com-redelivery.eu` — that is **not** an official DHL website. Real DHL uses domains like `dhl.com`, `dhl.de`, `dhlparcel.nl`, etc.
- **Generic greeting:** It doesn’t address you by name, which is a common sign of spam.
- **Urgency tactic:** “Pay within 24 hours or it will be returned” is designed to pressure you into acting quickly.
- **Odd fee amount:** Customs fees are usually more specific and tied to your actual shipment; €1.99 is a common “hook” amount used in scams.

**What you should do:**
- **Do not click the link.**
- **Do not enter any payment or personal information.**
- Delete the message.
- If you’re actually expecting a DHL parcel, check the tracking directly on the official DHL website or app using your tracking number.

Stay safe — this is almost certainly a fraudulent attempt to steal your card details.
