Same here. I have firstname.<digit>@gmail and I keep getting emails for the non-dot variant. And to add to the frustration, in order to unsubscribe some services require you to send an email from the same address. I've never hated Gmail's "convenience" feature of ignoring dots more. If they really wanted to offer it, they should have also given the option of adding/removing dots while sending emails too.

Someone even has a Paypal account on my dot-less email. It beats me how a payments company can let somebody add an email without verification and not offer an easy to way to remove it.
