Keep in mind that since these are all free services, your mileage may vary in terms of exceeding quota and uptime, and who knows when/if they will be taken offline down the road (exhibit A: Telize). Most of these services also offer a paid tier in case you want more features like SSL support.
Also, as skobaljic noted in the comments below, the request quotas are mostly academic since this is happening client-side and most end users will never exceed the quota.
