Should I thank the professor for forwarding me webinar/seminar invites? I work in the research group of one of the professors in my college. My professor forwards me emails which he receives regarding some webinars/seminars being organized in college/companies or articles related to our work. However, those emails are forwarded and don't contain any message personally written by him.
In such a situation, should I thank him for every such mail? (which I receive thrice per week) or will such frequent thank-you emails be deemed funny and spam by him? but if I don't respond in any way, I fear he will think I am ignoring his emails and my behaviour might be taken as rude.
What is common practice in such a situation?
I would suggest not for each of the emails. He probably just has a forwarding list and does this as a matter of course. Since you describe it as happening in a research group, he is probably trying to make sure everyone sees things that might advance the work of the group generally.
However, if you find any of them particularly useful for your own work, thank him for those, individually, and say why.
You could, in fact, return the favor when you see something that works for you and might for others in the group. Send them to the prof. and let him pass them on if he agrees on the value.
