When using a local welcome or community service, I think it is worth understanding exactly what information or benefits are being provided and whether there are any recurring communications involved. People moving into a new area may appreciate the service, but expectations can be different depending on how the program operates. I would keep the original registration details and any confirmation messages in case something needs to be clarified later. Before signing up, I’d also look at https://welcome-wagon.pissedconsumer.com/review.html and compare what other users have experienced so I could make a more informed decision.
