A problem that I repeatedly see firsthand and about which I receive many inquiries is the distribution of confidential documents from Excel. In the daily management of billing, accounts receivable, and accounting, it is astonishing to see how many hours administration teams spend on purely repetitive tasks—dealing with manual workflows that not only drain energy but also expose companies to critical data security risks. This is precisely why I developed Optipe's tools: to offer a safe, reliable, and definitive solution to this recurring headache.
Imagine this: It's the end of the month and you need to send invoices to 80 clients, sales reports to 25 branches, and payroll slips to your team. You copy files, change names, attach them manually, and double-check that everyone receives exactly what belongs to them… 2 or 3 hours later you finish exhausted and worried about sending the wrong document to the wrong person.
The risk is real: a client receives someone else’s invoice, a branch sees confidential data… and valuable time is wasted on repetitive tasks that could be used for analysis or sales.
Keep using manual processes, Word mail merge, or complicated macros? ❌

📊 The most common pains when sending documents from Excel
Searching for the right file, attaching one by one, and verifying each recipient.
Real pain: Easy to make mistakes and high risk of sending confidential data to the wrong client.
Setting up fields, merging documents, and generating deliveries.
Real pain: Complex, slow, and doesn’t always work well with multiple attachments.
Finding code online, adapting it, and debugging every time the process changes.
Real pain: Requires technical knowledge and constant maintenance.
AI generates a macro, but it often fails with files, folders, or real personalization.
Real pain: Not reliable for critical processes and still requires manual testing.
⚡ How MultiMail solves it in minutes
MultiMail works directly from Excel and Outlook, sending individual emails (not bulk) to avoid spam and ensure delivery. Here are the most used modes for invoices and reports:
1. Send Excel Workbook Sheets
🟢 Solution with MultiMail
Select the sheets that correspond to each recipient and send them automatically as Excel attachments or converted to PDF. Ideal for branch reports or management indicators.
2. Send Files and Documents
🟢 Solution with MultiMail
Automatically searches a folder for files that match the recipient’s identifier (ID, customer code, branch name) and attaches them. Perfect for individual invoices or payroll slips.
3. Send Multiple Documents per Recipient
🟢 Solution with MultiMail
Sends all documents belonging to one client or branch in a single email (invoice + purchase order + delivery note, for example). Automatically groups by code or identifier.
Example: Automatically Sending Management Reports by Branch
MultiMail scans your folder for files that match the recipient's name or ID and attaches them automatically.
With any of these methods, MultiMail eliminates repetitive labor and drastically reduces the risk of mistakes. Every recipient receives exactly what belongs to them safely and professionally.

| Task (50-80 recipients) | Manual / Macros | With MultiMail |
|---|---|---|
| Sending personalized invoices or reports | 2-3 hours | 8-12 minutes |
| MONTHLY TOTAL | 10+ hours | Less than 1 hour |
