Use Word mail merge to send emails, with all the missing features added back in. Features like adding attachments, having a custom subject, using the CC and BCC fields, using “Send As” (e.g. send as the CEO – you know you want to), and best of all you can save to drafts to check the emails before they go out.
Convert your Word Mail Merge into separate PDF documents! No third-party plug-in, no complexity, and no need to go moving and renaming documents.
