I recently received e-mails from two services: Paytm and Uber. They both seem like legitimate services. However I have no idea why I received these e-mails or why somebody would want to create an account with my e-mail.
The first e-mail provided a link to remove my e-mail from the system. I was wary to put my e-mail in, but considering that it had a valid HTTPS certificate and seemed legit on Google, I went ahead and did it (and received another e-mail confirming this action.) I also sent an e-mail to support for the other service and have not heard back yet.
What I want to know is:
Did I perform the right steps? Have I exposed myself to more risk by contacting these services?
Should I be worried? It seems that my e-mail account hasn't been compromised. I know that sometimes, companies will tell you to ignore e-mails if the action was not taken by you. However, I'm concerned because these seem like services that are easy to sign up for, but hard to disassociate with. I also don't want somebody just doing stuff willy-nilly with my e-mail.
