I am concerned that an email I sent can be interpreted as an (informal) acceptance of a postdoc offer.
The email was in response to a PI who emailed saying that he hoped to have an official offer out soon, and then asked about an ideal starting date.
I replied,"Thanks for the update! I could start at the beginning of xxx."
My intention with my wording was to give the information requested without accepting the offer, but also without explicitly stating that I was looking into other options. After sending this email I applied to other laboratories, and received a couple offers. All the offers, including the one referenced in the email, are almost equally attractive and I would like to select the option that works best for me. However, I do not want to be guilty of any dishonesty with regards to the original offer. Does my email pass as a firm commitment? I have since clarified to the PI during a call that I was considering other options and he did not seem too bothered, but I do want to make sure I am acting ethically.
I can provide more details but I have tried to include the most relevant.
