Send multiple documents per recipient, without errors
(invoices, orders, and supporting documents in a single email)
Sending the wrong or incomplete invoice can lead to disputes, payment delays, and loss of trust.
The innovative Multiple Documents capability of Optipe MultiMail revolutionizes document management from Excel by allowing you to send all the correct documents that belong to each recipient in a single email, automatically matched using codes or IDs.
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.
