We've been house hunting for the last year, and every time we book a viewing we're added to the agency's mailing list for other properties, without ever having been asked. In some cases we get multiple emails from different agents at the same agency (I've been told this is because at some companies the agents compete with each other rather than work together). Most of the properties they send us don't fit our search criteria - and the ones that do are already sent to us via Rightmove so the agency emails are completely unnecessary. Agents also cold-call us several times a week "to see how our search is going".
I passively resist all of this unwanted attention by blocking calls, auto-deleting emails etc, but I avoid actively complaining because I don't want to get on the wrong side of agents who I might one day buy a house from.
As the GDPR deadline date approached we did get an email from a couple of small independent agents asking us to confirm we wanted to remain on their mailing list, but the majority haven't bothered. We still get their emails, and there is no "unsubscribe" link to opt out.
It seems to me they're ignoring the legislation. Is everyone else finding the same thing in their area?
