In my opinion, Interfolio is not worth the price.
If you don't know what Interfolio is, I didn't either until one of my college professors asked me to sign up for it so he could send his letters of recommendations for my graduate schools through the site. I found out that Interfolio is a dossier site made to streamline college application processes. It helps by requesting, collecting, storing, and delivering academic materials to colleges or jobs by having an archived portfolio of your academic materials for professors to reference, as well as keeping their letters of recommendation saved for later use.
But here's the thing I didn't know when signing up for Interfolio: it costs money to use.
For free, Interfolio allows you to upload and collect your own documents, request and receive reusable confidential letters. But then you try to send your letters to colleges and it tells you that they will send your materials for, "faculty jobs, fellowships, grants, postdocs, or graduate study, for a flat $48 annual fee."
Even before I knew that Interfolio cost money, I was a little frustrated. My professor didn't have time to upload his confidential letter to all my applications, which is understandable considering how many requests he gets from other students while also teaching classes, but I was still a bit annoyed. So, I had to go through and input a linked email to Interfolio instead of his personal email so that the Interfolio staff could submit the letters for me.
But not all the applications using Interfolio worked. For some schools, I got an email from Interfolio saying they couldn't submit because in order to submit the letter, it asked personal questions they couldn't answer, like how long the professor had known me. Not only that, but some schools were just completely incompatible with Interfolio when I tried to put in the information for the site. Then I had a friend who was also doing graduate school applications message me about the site because it wouldn't let her send letters because her professor hadn't uploaded their letter of recommendation yet, despite deadlines approaching.
So, I had all these complications on top of paying an extra almost $50 that I hadn't budgeted for, in addition to applications fees and costs for sending test scores and transcripts. I was still extremely grateful for the letters of recommendation from my professor, but I only needed it for graduate school applications, so now I have a subscription to Interfolio for a year that I am never going to use again.
If you will use Interfolio for a full year for not only school applications, but also job opportunities, it may be worth getting for you. But for me, it would have been less complicated to just email my professor back and forth. I wish I hadn't had to go through a third-party website.
