Give Up error When running campaign using gmail. Successful when i send a test campaign.

I am using gmail as the smtp server. When testing the campaign I dont receive an error. However when i start a campaign all the emails sendouts are failing with the error giveup

Most likely because you're sending too much, too fast. GMail should not be used for bulk emailing.
