Introducing the New reMail

Today, we're launching the new reMail for the iPhone! It's a completely new product.

reMail downloads all your email to your phone and lets you search full-text at light speed.

All My Email On My Phone? Really?

Yes, reMail downloads all your email to your phone. It will let you read and search all your email when you're offline. Just let reMail run overnight to complete the download. reMail needs less space than you think: 100,000 emails take only 500 MB on your phone - only 6% of the capacity of an 8 GB iPhone (the smallest iPhone you can buy).

This Will Save You Money

My family lives in Switzerland and I live in San Francisco. One thing I've found very frustrating whenever I travel to see my parents are the insane fees that AT&T charges for data roaming: For Switzerland, AT&T charges $19.97 per Megabyte. Check out this SMS I get the moment I turn my phone on the tarmac in Switzerland.

Now, with reMail, I don't have to think twice about searching for meeting times or flight reservations. When I'm abroad, I just download all my email over Wifi and have data roaming turned off.

We put together this page that contrasts data roaming prices with AT&T and T-Mobile Germany with the cost of reMail.

reMail Searches Full-Text

Another crucial difference between iPhone 3.0 Mail and reMail is that reMail searches full-text.

The built-in header-only search is frustrating, because so many times, the words I'm searching for don't appear in the To, From, and Subject lines. If the words you search for aren't in the headers, reMail will find the email, iPhone Mail will not. reMail is email search you can trust.

What happened to reMail Search Beta?

We launched reMail Search a few months back, it was a server-based product. Searches were being done on the server, and you had to give us your email password. It turns out people are very opposed to sharing their email and password with third parties, especially a small startup.

So we built the new reMail. Now, everything happens on the phone. reMail downloads your emails directly via IMAP. No more reMail server.

What reMail Users Are Saying

We have beta tested the app with a lot of users, and they are loving it:
  • “This app is awesome! I use reMail constantly all day. It's so fast!”
    — Sachin Agarwal, Co-Founder, Posterous
  • “I am loving reMail!”
    — Richard Price, CEO, Academia.edu
  • “Complete Berlin trip organized via emails found by reMail. No printed reservations and tickets needed!”
    — Bernhard Heinzel, Beta User
  • “reMail is a super useful app and search speed is incredible.”
    — Dan Veltri, Co-Founder, Weebly

Get it Now

We hope you'll love it too. Get it now. It's $4.99 on the App Store until Sep 1, and $9.99 thereafter.

Update: Coverage here and here.

Releasing Something New, Every Week

I'm trying something new: For the next four weeks, reMail will be releasing a new feature or product every single week.

Pretty radical, eh? Here's why I'm doing this: I'm a perfectionist and need to be constrained by time rather than "good enough". Here are the three recent events that triggered this experiment:
  1. I organized a Post-YC dinner for my former batch and invited Dropbox Fouder/CEO Drew Houston to come and speak. He talked about Dropbox's private beta period, and how early audiences don't care about perfect; They care about new ideas and usefulness.
  2. I built reBoxed, an experiment in email prioritization, in 3 days, with that specific deadline in mind. Despite being a work-in-progress at launch, the result was successful and gave me plenty of new ideas.
  3. I need to start testing my hypotheses about email users (if you've been reading this blog, you know I have a lot of them), and there's no better way to do that than to give them a product to play with.

I have a couple of these products/features in various stages of completion, so I know roughly what I'll be doing for the next few weeks. I'm also thinking about charging for some of these products and features from the get-go, Eric-Ries-style. "Buy before you try", if you will. More on that later.

I'm leaving for a weeklong trip to Europe on May 26 to visit some friends, and that week will conclude this experiment. Until then, watch this space.

Delayed Sending of Email

Every once in a while, people pitch me a new feature for Outlook: "This is something I'd use every day!" For a large percentage of these, Outlook already does what they want, and it's just hard to find it.

A good example of this is delayed sending of email. Instead of sending the email when you hit "Send", you want to automatically send the email at a later time. Maybe you don't want to give someone the impression that you respond to their emails instantly. Or your press release goes out at midnight but you don't want to be awake at such a late hour.

This feature already exists. In Outlook 2007, it's called "Delay Delivery". When you're composing a message, click the icon in the menu bar, then check "Do not deliver before". In Outlook 2003, click "Options", then "Do not deliver before".



This is a great illustration of both Outlook's greatest strength and greatest weakness. I can easily imagine the corporate IT meetings in the mid-1990s where admins compared the feature matrix of Outlook to that of Lotus Notes, and decided to go with Outlook. Microsoft got everyone to use Outlook partly because it had a complete product with every feature box checked. On the other hand, it created a client with a lot of complexity, where every new release needs to carry the weight of the last one to assure backwards compatibility. Complexity leads to long cycles, and slow products. However, it can also lead to market dominance.

Xobni's Journey to the Right Product

This is the second of a three-part series on the Xobni launch. Come back on next Monday to check out Part III of the story. Co-written with Marie Baca. An abridged version of this article was featured yesterday on GigaOm.

I often speak with entrepreneurs applying for funding from YCombinator, and when I do I give them this advice: the most important decisions you make are the ones in the beginning of the process. Choices like what product to build and what market to serve determine whether you’re headed for failure or a multi-million dollar exit. Marc Andreessen, founder of Netscape, calls this "product/market fit" and says that it’s the only thing that really matters when it comes to building a company.

It's fair to say that at Xobni, is that we stumbled into product/market fit. We initially built the wrong product, but then we quickly corrected our course.

Building the Wrong Product

When Adam first wrote up our YCombinator application, Xobni was called "EmailDM"—the DM stood for "Data Mining." Adam included demos of how EmailDM would summarize emails, highlight important passages, and so on. Eventually this vision morphed into Xobni Analytics, which lets you analyze email usage by creating a diagram of your message traffic.



The initial plan was to offer this program to companies as a productivity tool. Workers would install the software into Outlook and use the data to find ways to become more productive. We would then offer this product to corporations so managers could remotely monitor employee email productivity.

This Boston Globe article, the first major coverage of Xobni, illustrates why this model was a bad idea: employees would feel like they were being spied upon. But even beyond the spying problem, Xobni Analytics was the wrong product to build for a more important reason: users would install the software, browse it for a bit, and then close it and quickly forget about it. Analytics was not a sticky application that tempted users to come back again and again.

The Xobni sidebar is completely different. There are many features beyond the analytics that add value for the user. Plus, the sidebar sits right next to the inbox, so users are exposed to it for the 2 hours they spend checking their email every day.

Our mistake became even clearer when we shopped early versions of Xobni around to venture capitalists. We first tried to remedy this problem by designing something called Xobni Feeds, which allowed users to create different types of XML queries that we would show up in the sidebar. Only later did we realize that this way too much flexibility for the average user, and we decided that it was a much better idea to show relevant, people-based default information.

In short, we discovered that our product was most successful when it provided focused information about people, not numbers. It is essential that entrepreneurs remember that they are serving an audience of individuals who need simple solutions to their everyday problems.

Why Outlook?

Unlike the initial problems with product development, Xobni made the right decision early on to target the Outlook market. There are an enormous number of Outlook users out there (around 350-400 million, depending on whose numbers you trust), and yet there is also major dissatisfaction with the program.



After Outlook, users most often requested that we build Xobni for Gmail and Apple’s Mail.app. However, both of those clients have much lower pain levels than Outlook. In addition, the addressable market is much more interesting: Outlook users are more likely to have business credit cards so if we ever switch to a freemium model, we can charge them. Also, there’s a strong demand for advertising partnership opportunities within Outlook, an application that users interact with for hours each day.

I like to think of it this way: there are a huge number of Outlook users out there who are so frustrated with the program that they feel like there hair is on fire. What Xobni offers is a cold bucket of water.

A Generalized Architecture

One of Xobni’s major differentiators is that we didn’t build a simple addin for Outlook, but an email application platform. Whenever we write software, we aim for a more general solution than what is required by our current needs. We can easily build new applications and build integrations into other email clients, as these leaked screenshots illustrate.



Building this platform took a significant amount of time and effort, but I’m happy that Adam made this decision early on: It allows us to quickly iterate on functionality, and build new, exciting products in the future!

Choosing a Look

Here are some mockups I created more than a year ago that illustrate the looks we had in mind for Xobni. The mockup on the right was our original choice: it blends nicely into Outlook, almost as if Xobni was built into it from the start. We created the third one almost as a joke, to show how the sidebar would look if we used a funky color palette.



We decided to go with the bright, saturated colors, because it would have what we call the “What the heck is that?” effect. Jane would walk by Jack’s desk, and see a bright blob on the right side of his Outlook screen, and she would blurt out: “What the heck is that?” Jack would have to explain Xobni and what it does, and Jane would probably download it once back at her desk.

Search as an Afterthought

Ironically, Xobni’s search function was initially an afterthought – Greg Duffy implemented it just a few days before we launched our private beta at TechCrunch 40. Even considering the rapid pace at which startups do product development, this was an immense accomplishment: Xobni’s search is twice as fast as Outlook’s, thanks to highly optimized and efficient search indexes. That combination of speed and usefulness make search our top-clicked feature.

Launch!

Let’s say you have a great product. How do you know when you’re ready to launch? That’s what I asked Gmail creator Paul Buchheit two months before our launch date. At the time, Paul was pretty skeptical, but he inspired us with an idea he repeated at Y Combinator's Startup School: Before launching Gmail, Eric Schmidt gave him the assignment to find 100 happy users. After talking to users, and eliminating their top feature requests and bugs, they met that number and thus, Gmail was ready to fly. We followed a similar spirit by adding the Are You Happy box to the product, and by listening closely to customers via our support team and users we knew personally.

We originally launched a private beta at TechCrunch 40, a conference where 40 startups launch their product within 2 days. The schedule was very tight, and the days leading up to it were a chaotic blur. In retrospect, we probably launched a little earlier than we should have. The product hadn’t been heavily tested at that point, yet we grew our user base by 50x that very day. With our open beta launch on Monday, we were finally ready in terms of speed and stability, and the feedback since has been extremely positive:
"Xobni is such a simple idea, but it is sure to radically change how you handle email." - Tom Spring, PC World
"For those who work in the corporate world - where Outlook is still heavily used - Xobni's public beta will be of great help, allowing them to quickly find and expose the data trapped in their inbox." - Sarah Perez, Read Write Web
"This plugin looks like it would be insanely helpful. Gmail, are you paying attention? :)" - Comment by Ross M, Lifehacker
"Given that Outlook is pretty much de rigueur for most corporate e-mail systems, this should be a welcome addition for those of you trapped in Outlook at work." - Scott Gilbertson, Wired
"Oh Microsoft, you’ve missed the boat yet again it would seem." - Zach Epstein, The Boy Genius Report
"In just a short few days, I can already share my belief that Xobni is a must download for Outlook users." - Kevin Tofel, kjOnTheRun
"Designed to make it easier to handle the deluge of daily messages, Xobni integrates with Outlook and - to quote our original review - becomes an invaluable weapon in the daily war with email." - Tim Danton, PC Pro

Thanks to Evan Solomon and Sean Ellis for reviewing drafts of this article. Be sure to check out Part III of this series, where I’ll talk about how we built a great company, assembled a superstar team, and built a culture that encourages building solid products.

The Cost of Switching Your Logo

When big companies change their logos, brochures have to be reprinted, signs changed, and trucks repainted.



About a week ago, Xobni switched to a new, lowercase logo. It eliminates the dash above the o: Since the Bill Gates demo, the short o has fallen out of favor. In addition, the new lowercase format allows us to mirror the logo on our homepage to make the "inbox backwards" connection obvious.

After Bryan created the new design and put it up on the website, I decided to switch our logo everywhere else. Original estimate: 1 hour.

I changed the logo in the product, our internal Wiki, the bug tracker, Nimda, and even ordered mousepads with the new design. Then, I figured out how to change our logo on Wikipedia, and even wrote an email to Crunchbase asking to change our logo. Total time taken: 3 hours! And I'm sure the old logo still lingers somewhere.

If this small change takes hours even for a startup like ours, I can see what corporations spend those millions of dollars on.

Three Clever Xobni Features (2/3): As-you-type Search

This is installment 2 of 3 blog entries about features in Xobni where I discuss well-implemented, clever ideas. None of these are Xobni-specific – you should be able to port these ideas to any web or desktop app.

Previously: Three Clever Xobni Features (1/3): Are you Happy?

Traditionally, you type in the query, hit Enter, and get the results. In Xobni, you start typing your query and we start showing you results as-you-type.



Outlook 2007 has a similar feature: When you type and pause for a bit, it starts a search in the background. But it's the same operation at the same speeds as their normal search. In contrast, our search indexes and data files are optimized for incremental search: We search for prefixes, not full words. This makes us much faster.

Three Clever Xobni Features (1/3): "Are you Happy?"

This is installment 1 of 3 blog entries about features in Xobni where I discuss well-implemented, clever ideas. None of these are Xobni-specific – you should be able to port these ideas to any web or desktop app.

We're religious about user feedback at Xobni. We get dozens of emails every day and read every single one. If you uninstall us, we ask for comments around why you uninstalled and how we could improve. We've built tools to collect and summarize this data.

But most users aren't vocal about their needs. The average happy user is unlikely to email with small problems she might be seeing. We want their feedback, but can't just pop up a window with a survey every time you use the software.

That's why we built Are you Happy?: Instead of a popup, we add a little box on the bottom of the sidebar every couple of weeks and ask: "Are you happy?" There are two buttons, Yes and No, and an optional comment field.



This is the most lightweight method of collecting user feedback. Note that:
  1. We're not popping up an annoying window.
  2. We ask a simple question.
  3. There are only two options – "yes" and "no" - and no Send button.

If we introduce unpopular features or bugs, we know within a few days. This feature was inspired by a similar mechanism in the early days of Caribou.

Currently, 90% of our users answer "Yes".
