Open Letter to Long Lost Contacts

Ich habe mir aus einem E-Mail Archive alle Mailadressen rausgesucht mit denen ich in den letzten 6 Jahren Kontakt hatte. Das waren 7303 Stück. Ich löschte alle Adressen die eine Rolle erfüllen und keine Einzelpersonen bezeichneten. Blieben 5466.

Für einen Moment überlegte ich, alle anzuschreiben und formulierte sogar unterstehenden Brief. Auf Englisch, da ich mir dachte, dass die Mehrzahl meiner Kontakte das verstehen müsste. Aber dann liess ich von so einem Massen-Mail ab, weil das vermutlich nur mehr Ärger gebracht hätte als Positives.

Stattdessen veröffentliche ich Brief halt auf meinen Blogs. Da ist es weniger aufdringlich.


I am trying to reach out to long lost contacts. For this purpose I scanned my email archive for all email addresses in the to and from fields and imported this list into a Mailchimp list. By sending this email to this list I can see who remains subscribed and which emails bounce.

Sorry to bother you like this, in bulk, but I saw no other way how to go through this list of 7000 people. If you feel bothered by this, simply ignore it because this is the only message I will ever send to this list.

However if this reminds you that we had an interesting contact in the past, please feel free to get in touch again by any of the means mentioned below.

Since I don’t know whether we had professional or personal contact let me mention updates for both sections. And you may ignore whatever you are not interested it. Deal? 🙂

Business Updates

I am a full time iOS and Mac developer for 7 years now. I work with two smart people who are working for two clients, one in Germany, one in USA.

Over the past 8 months I wrote an iOS development book on barcodes and how you can leverage these in your iOS apps. This book gives you an overview on the bar codes supported by iOS 7 and up and will open your eyes for new app ideas everywhere you see a barcode.

Now that my book is almost finished I am on the lookout for new development work. If you need something developed, I might be what you are looking for. This article gives you an overview of what I have to offer.

I’ll also pick up writing about development topics on my blog. These are the advertising opportunities for you there:

Next to my software development business, I founded ProductLayer with two friends. It’s a startup looking for partners and investors. Read more about it here:

Personal Updates

I moved back to Austrian’s capital Vienna in April, into an apartment that I owned for 17 years now. I am recently single/divorced. I lost 11 kilos since the beginning of the year with a combination of Herbalife and lots of physical activity.

I have to admit that during my time in the countryside I let many personal connections lapse. You might even say it was my arrogance, believing that I won’t need friends because I had received the ultimate life upgrade: marriage.

Let’s not dwell on the past, though. It is no problem if you make mistakes. It is only a problem if you don’t learn from them.

I’m curious what happened to you since we last spoke/e-mailed. What’s going on in my personal life you can see at any of the social media outlets mentioned below. If you feel like talking, get in touch. If not, then just save my address…. you never know.

Whether we had business or personal dealings in the past… if we lost our connection, let’s re-connect!

But if you don’t want to hear from me ever again, simply ignore this update.

kind regards
Oliver Drobnik
