What are limits to these methods ?

Cross use of several of these methods allows excellent results concerning comments, but weak results concerning trackbakcs.
Difference between comments and trackbacks is that comments are sent from recipient’s blog, which allosw all above methods to be used, whereas trackbacks are sent from shipping blog (this avoids use and need of 2 interfaces).
- Consequently it’s not possible to use CAPTCHA, authentication and Secure Form Mode methods with trackbacks.
- Another big problem, when all trackback’s data are unknown, especially IP address, it is quite impossible to avoid spam, mainly because blacklist and bayesian filter are becoming inefficient.
- Last inconvenient, trackback autodiscovery is usefull for bookmarklets but also to spamers to who it gives trackback URL.

4) DON'T SHOUT! USING ALL CAPITALS IS DIFFICULT TO READ AND LOOKS AS IF YOU ARE SHOUTING. DON'T DO IT!

Occasional use of capital letters to emphasise a word is ok, but be aware that some spam filters delete email messages with words all in capitals.

5) Call To Action The first two sentences of your email should identify a possible problem recipient may have, tell them who you are, and what you want them to do.

6) Conclude & PS If you have a fairly long email, don't forget to repeat call to action at end, and in a PS to remind reader once again what they should do.

7) Sense of Urgency Create a sense of urgency by using phrases such as 'First 50 to apply' or 'Only valid until' - fear of missing out on something always generates a good click through - guaranteed
