Smarter Mail Merge, right inside Word — with attachments and no subscriptions.
I created MailMergeExt because I understand the frustration of trying to send personalized emails with attachments using Microsoft Word. As an experienced IT professional and software developer, I saw too many organizations wasting time on manual processes or paying for expensive cloud-based solutions that store sensitive data on third-party servers.
With over two decades working in IT systems and automation, my mission was simple:
to build a lightweight tool that empowers you to send customized emails (with attachments) straight from your own Outlook account, keeping full control over your data.
