Just send it!
We all get busy and start pressing the snooze button on tasks such as 'Send Email Newsletter' and I am no exception. Which prompted me to post this tip: Just send it !
If you are waiting for the perfect newsletter or message then you will also waiting for some time. I logged on to send this one and edmBlast jumped up and said 'Hey where have you been... you sent your last tip on March 4th!' .... Oops
So just send it... but test it as well.
