Important:

Meanwhile Jax Newsletter is a little bit "out of date". If you are asking what follows next and whether there will be support for Jax Newsletter i can give you the answer "definitely yes"! Jax Newsletter will be completely redesigned till the end of this year. If you are under pressure you can check:

Lovefully workmanship - good improvement of Jax Newsletter. Not much in common with the original, but the handling is much better. Stores data to flat text files but has not html support yet...
