I have received a payment request from the email address noreply-ecom@dpd.de and I am supposed to pay import VAT. Is this an official email from DPD?

As soon as the parcel is on its way to Germany, you will receive an email from the email address noreply-ecom@dpd.de requesting you to pay the import duties. This is an official DPD e-mail address. You can pay your import duties conveniently via the payment platform of our partner eCom Solution GmbH. A link in the email will take you directly to the platform.
