Based on this error message, you have set your gmail limits for sending email, check my reference link : http://www.labnol.org/internet/email/gmail-daily-limit-sending-bulk-email/2191/

By the way, may i know did you have setup cronjob in your site yet? If no, can you temporary disable this option from your backend > Easyblog > setting > notifications > general > Send emails on page load - NO and see how it goes?

If still slow. can you provide us with your Joomla backend and FTP access so we can better have a look?
