I received an unsolicited email from In Residence Bangkok Sukhumvit 13 hotel offering me discounted stays for this year and recognizing a stay with them in February. I've never stayed with them nor contacted them. This email came on my second day in Thailand. My best guess at this time is an employee at one of the two hotels I stayed at is selling guest information. I had a stay at a different chain in February but cancelled it when my trip was postponed so that hotel could be the culprit. The only other source I can think of would be when I registered for the free AOT internet service at BKK. Anyone received a similar email?
