Attach a different document to each recipient, without errors
(invoices, certificates or individual reports sent directly from Excel)
Sending the wrong file to the wrong person can lead to complaints, rework, and confidentiality issues.
The Files and Documents capability of Optipe MultiMail allows you to automatically attach a unique and correct file for each recipient, directly from your local folders, ensuring accuracy and control in every send.
Need to send hundreds of personalized documents directly from Excel?
Optipe MultiMail automates personalized email delivery directly from Excel through Outlook. Each recipient can receive a customized message and their own attachments, processing hundreds or even thousands of emails in minutes—without macros or programming.
It runs entirely on your computer, works with your own Outlook account, and is designed for professional processes where security and full control of your information are essential.
Important: MultiMail is not an email marketing platform. It is designed for the professional distribution of personalized documents in internal processes such as Finance, Human Resources, Operations, Education, Healthcare, and other administrative departments.
