Translation of Anspannung

Dear Maximilian, I look forward to your visit in Switzerland. After a somewhat difficult start, it seems that we have increased the website traffic and we are starting to receive more visitors.
And in the end you still have not learned what you have wanted. I browse in online stores all day and come back empty-handed, or with items that I do not really need. Learn and think about it.
I sent a letter 2 days ago. Did you get it? I see that you like sports. I play tennis. Maybe we can communicate together and write about sports and learn Spanish that way. Waiting for your reply.
