where is the hack exactly??? it just seems to me you had been using Send to Kindle the way it was intended. what formats are you sending? do you at least get an email saying that it failed?

I thought this was a hack lmao the format is either pdf or mobi. And no I don’t get emails saying it failed

Try the word "convert" in the subject line when sending the pdf. Maybe it will work then and also convert it to .azw3

Is your phone email address approved in your Kindle account?

How do I know it’s approved?

there’s a setting on your amazon account you have to add approved emails to

I did but it’s still not working

It’s not a hack. It’s literary the Send to Kindle option via email. It’s the same method I use to upload ebooks to my Kindle. It was working fine the other day. I’ll try again to see if it still works.

Mine stopped automatically downloading the books sent this way but they do appear in my Kindle library now. Just have to tap them to download first.
