I'll have more to say about some of the larger issues around this in a few days, but now that the embargo has been lifted (damn you, Om Malik), I wanted to point at the pair of announcements from Yahoo! Mail today and yesterday.

The Bottomless Inbox

Yesterday came word of "unlimited" storage for all mailboxes on Yahoo mail. What can I say, storage is getting cheaper all the time.


Today's news is that the Yahoo! Mail API that we previewed at last year's Open Hack Day is now available to all developers. It speaks both SOAP and JSON-RPC and is well documented. The SOAP API is the same API that the mail front-end uses to talk to the mail back-end mail system, so it's the real deal. There's sample code too. And even apps it the gallery.


In the last few weeks, Matt McAlister and I sat down to talk with a few folks using our "screencast interview" style. So I present two videos for you Quicktime viewing pleasure:

We'll have lower fidelity versions up on Yahoo! Tube Yahoo! Video before too long.

Make Money Fast

Oh, I should also mention that if you build the next killer application and convince people to use it and upgrade to the premium version of Yahoo! Mail, we'll pay you $10 per user. The sky's the limit on how cool your mail front-end can be. We'll handle the infrastructure.

This stuff has been in the works for quite a while and a whole team of people has been putting tons of work into make sure it all works right--especially Ryan Kennedy.

So why can't we use this for unlimited data storage? If you've gone this far, you may as well have also created an S3 competitor. Storage is cheap, right?

Thanks Jeremy! It was awesome doing the screencast with you, Matt and Dan. You do a great job leading the conversation so I never feel unsure of what to talk about. ;)

I think Om's opening statement said it best: 'What took them so long?' Definitely a big step for Yahoo!, and I agree with Jeff Barr, very interesting incentive program! :)

There is one VERY IMPORTANT problem keeping me from endorsing Yahoo! Mail, even though I've been a dedicated user for years now, and I would love a stack of $10 bills. I've emailed support, but this problem is so critical that I'm putting my morals aside and mentioning it on your blog: attachments to new messages won't download correctly (in Y! Mail Beta), sometimes for many hours after I've received a message. Forwarding the messages to GMail immediately solves the problem. You're a powerful man; talk to someone, please!

Greg, shoot me email and we'll see if we can troubleshoot. This is the first I've ever heard of this problem.

I could not find a similar post, but everthing is related, last words of Plato. I have Win2K O/S and dialup, but recetnly Yahoo has been very slow in launching and Google' search results when clicked is the same problem.Like 2-3 mins, and Modem runs at 50.6 Bps. Is this a network load problem or my system?

Hi Jeremy

do you know of anyone that has written a program that uses yahoo mail, but can strip out all attachments and store the sttachments separately? What I mean is, have separate folders that used for storing documents a folder for pdf's, a folder for .doc, one for other types, etc, and a search function that lets you search the contents of those filez as well?

Suresh, you can do this pretty easily with the web service if you want. It's an odd feature request, though. The built-in search indexing will do all of this for you even without sorting attachments into different folders. There are search shortcuts that allow you to restrict results to messages that only have attachments of a certain type. Additionally, the search indexer looks inside of textual attachments, so searches will find instances of the query either in the message text or in the attachment.
