NOTE: As of 2014, emails sent to AOL or Yahoo are more than likely being blocked if they are sent on your behalf. This is how ResponsiBid sends emails by default. By following this guide to use your own email servers you will be far more likely to be able to deliver to this addresses since they will be coming directly from your email account.
You can setup your emails that go out through the follow-up builder to use the default ResponsiBid servers to send on your behalf, or you can setup your Google or Yahoo, or custom email address to directly send all of your automated emails. It’s a great way to stay out of the spam box, and make sure that your emails look as genuine to your customers as possible. It also allows you to have a record in your “sent” mail of all the emails you’ll be sending in an automated way.
