Email is best if you have information for me.

If you call, I'll have to write it down and there's always the chance of getting something wrong. Text meassages are

also good.

 

If you have something to discuss, please call me.

If I don't answer, I'm probably with someone or deeply into something that has a deadline. I'll call you back as soon as I can. If it's seriously urgent a text would be good:)
