Sending Mass Email (Salesforce Classic) | Salesforce

Can plz share the product link?

Its really useful thank you

Is this also available in the Lightning version or SF? If so, is there another video showcasing that mass email process?

Thank you so much. This was truly very useful.

May I ask you, I'm using Group edition version, and couldn't find mass e-mail function. Do this version can use mass e-mail fuction? How to set up? If not, how to get this function or what I need to do to have this fuction?
