Sending mass email to a list of more than 100 recipients in one go?

Sending mass email to a list of more than 100 recipients in one go?

I'm not sure if this is just me, but if I want to send a mass email from a contact list (for example) that has more than 100 contacts, I have to open multiple tabs and have contacts 101 - 200 on a separate tab to then select them, as if I select all on the first page then click to go on to the next page of 100 I get a 'Unable to process your request'.

Does anyone else have this issue, and if so; do you have an easier work around than opening multiple tabs to send to list of more than 100 recipients?
