**No, this is definitely a scam (phishing).** Do not click the link and do not enter any personal or payment information.

Here’s why it’s fake:

1. **The URL is a dead giveaway**: The link is `https://dhl.com-redelivery.eu/...`. Genuine DHL websites end in `dhl.com`, `dhl.de`, etc. This link tries to trick you by putting "dhl.com" **before** a hyphen, but the actual domain is `redelivery.eu`. Legitimate companies never use hyphens in this way to try to mimic their domain.
2. **The timing and amount**: Scammers use small, urgent amounts (like €1.99) to make you act quickly without thinking. Real customs fees are calculated based on the item's value, VAT, and handling charges, and they are rarely exactly €1.99.
3. **The threat**: “Returned to the sender within 24 hours” is a common social engineering tactic to rush you into acting before you can verify.
4. **Lack of specifics**: The text doesn't include a tracking number or your name, which a genuine notification would have.

**What you should do:**
- **Do not click the link**, do not reply, and do not provide any card or personal details.
- **Delete the text message**.
- If you *are* expecting a package, check the status directly by going to the official DHL website (type `dhl.com` into your browser manually) or using the official DHL app, and look up your tracking number.
- You can also report the SMS to DHL's official phishing report email (e.g., `phishing@dhl.com`) or forward it to your phone carrier's spam reporting number (e.g., 7726 in the US/UK), though deleting it is enough.

Legitimate customs fees for international shipments usually require you to log into your account or pay through the official carrier's website using a tracking number, never through a link in an SMS like this.
