First I had a Daily Digest where I put everything I was interested in. Feeds, tweets, even a few youtube channels. I had the whole thing sent to me 3x a day. In the morning, at noon and in the evening. That was actually quite good.
Now I have changed it: I took out the tweets and had an extra newsletter generated for them. This also comes 3x daily at similar times. Both seem tidier this way, but, although it’s the same amount, it now seems to me as if I’m overwhelmed by mails, especially since I then again took something out of my Daily Digest and put it into an extra newsletter. So now I get 3x3 newsletters a day. I don’t think that was a very good idea. On the other hand Mailbrew gives me the possibility to do exactly such studies. And someday I will find the perfect result for me!
