As long as you mean looking elsewhere just for email. It would seem silly to leave the best LLU ISP over it as all ISP email systems seem flakey to me.
I have used Purple Cloud for well over two years and am still very satisfied. Now costs £7.34 for your domain for 2 years and £10 per year for Home email to go with it. 1&1 seems to have a good reputation as well.
I don't fancy having all my email going through Google even if it is free. At the time I signed up to Purple Cloud you couldn't have your own domain with Google anyway, and it was just webmail as well which I cannot stand for normal use.
