Bogus congratulations from supposed Strava users after Zwift races

Anyone else receive these via e-mail just after logging a ride? I am registered with Strava but never use it. I allow Zwift to upload my race results to Strava in case I ever want a record there but that's all. I am not connected to any Strava users to my knowledge.

If Strava thinks this will persuade me to pay them a fee they have another thing coming. It's just spam and I have cut them off.
