Accidentally clicked on a strange link

Yestarday I received an e-mail message from a well-known chain store restaurant (that does not function in my country, but nevermind) that was claiming there is some offer waiting for me. At first I thought it was a message sent as a result of adding me to some distribution group - it didn’t include any personal info. I wanted to resign from receiving such emails but such option was not there. And so I clicked „my dashboard” - it opened a real website of this restaurant with an information that it can’t be reached (as I mentioned, the restaurant is not located in my country).

I then realised that it might have been just spam but also it could be phishing. I changed all my passwords and brought back dafault settings.

Do you think there’s anything to worry about?

Just one more thing - my iPhone is not jailbroken and I use Safari.

Hope you can help.
