**No, this is not real.** It is a phishing scam.

Here is how you can tell it is fake:

**1. The Website Link is Fake**
Legitimate DHL emails will always come from an official `@dhl.com` address (e.g., `dhl.com-notifications@...` or similar). The link provided (`https://dhl.com-redelivery.eu/p/8KX2Q`) uses a suspicious domain structure. Official DHL payment portals do not use subdomains like `dhl.com-redelivery.eu`.

**2. The Fee Amount is Too Low**
Customs fees (VAT and duties) are rarely as low as **1.99 EUR**. Scammers use small amounts like this to trick you into thinking it's a legitimate, minor charge. Real customs fees are usually much higher.

**3. High-Pressure Tactics**
The message claims you must pay "within 24 hours or it will be returned." This is a classic psychological trick used in phishing to make you panic and click the link without thinking.

**What you should do:**

1.  **Do NOT click the link.**
2.  **Check your tracking directly:** Go to the official DHL website (dhl.com) or use the official DHL app. Enter your tracking number there to see the actual status of your package.
3.  **Contact DHL directly:** If you are worried about a real package, log in to your account on the official DHL website to see if there are any actual holds or fees listed.

**Summary:** If you didn't expect an email about a customs fee, or if the link looks suspicious, it is 100% a scam. Delete it immediately.
