Sending a second reminder to a professor about LORs, after the first reminder As graduate school application deadlines roll around this season, I believe this site would get a lot of questions concerning letters of recommendation, including sending reminder e-mails to professors about this.

My question is now what is the best approach to sending a second reminder to a professor concerning writing an LOR? A couple months ago, after having discussed my graduate school plans with the professor, they agreed to write his letter and have me send them the e-mail link to the LOR. I sent the first reminder last week, but they did not respond. And this professor is normally responsive in e-mails about other things, such as coursework and advising. I suspect the professor is beyond busy, and I hope that is the case; I just hope they haven't forgotten about the LOR or changed their mind about it.

I would like to add further that my two other recommenders have already submitted their LORs. I am still waiting on this professor now. Should I mention this in my second reminder e-mail to them, if I should send that second reminder at all? What should I be saying in the e-mail, to politely remind them for the second time?

Any input helps.
A week since your first reminder is somewhat on the short side - personally I would wait a couple more days (maybe two weeks since the last email) to send another email. 

A week before the deadline is a good point of time to send a reminder. There is no need to state that this is a second (or nth) reminder. A short email, roughly of the form 'thanks again for agreeing to write a recommendation letter for me. I just wanted to quickly remind you that the deadlines are one week away. Please let me know if you need any more information from me. Thanks again for all your help, etc.' is sufficient.
