Not only do you risk that your subscribers forget about you (and turn to the competition), if your newsletter is sent very infrequently — less often than at least once per month — it also stands a big chance of being perceived at spam.
The result may be lots of puzzled faces, unsubscriptions and complaints to your ISP calling you a spammer — all that in spite of your subscribers (actually) demanding and liking your content.
That's why you should
- send newsletters at least once a month to prevent
- bulk unsubscriptions and
- being perceived as a spammer.
