Absolutely, there are several no-code solutions to automate sending each split 7z file as a separate email to the same recipient—no scripting or coding required. Let’s walk through the most practical, user-friendly options:

This is the simplest option for non-technical users, as it’s designed specifically for batch email tasks with attachments:

• Download and install the free version of SendBlaster (no paid subscription needed for this use case)
• Launch the tool and set up your email account (supports all major providers like Outlook, Gmail, and Yahoo via SMTP/POP3)
• Go to the Recipients tab: Add your single recipient’s email address (you can either type it directly or import a 1-line CSV file with their address)
• Switch to the Message tab: Write your standard subject line and email body. You can use the built-in variable %ATTACHMENT_NAME% to auto-include the split file’s name in the subject (e.g., "Split File: %ATTACHMENT_NAME%")
• Navigate to the Attachments tab: Click "Add multiple attachments", select all your split 7z files, and the tool will automatically create a separate email for each attachment
• Finally, click "Send" to dispatch all emails at once

If you prefer using a desktop email client, Thunderbird’s free Mail Merge extension lets you handle this without code:

• Install Thunderbird (if you don’t already have it) and add the Mail Merge extension from Thunderbird’s add-on store
• Create a simple CSV file with two columns: Email (repeat your recipient’s address for every split file) and AttachmentPath (paste the full file path for each 7z part, e.g., C:\SplitFiles\archive.part001.7z)
• Open Thunderbird, draft a new email with your desired subject and body
• Click the Mail Merge extension button, select your CSV file, map the Email column to the recipient field, and map AttachmentPath to the attachment field
• Confirm your settings and start the merge—each split file will be sent as a separate email to your recipient

While Outlook’s native mail merge doesn’t support auto-attaching files directly, you can use a no-code workaround with Excel:

• Create an Excel spreadsheet with two columns: RecipientEmail (same address repeated for every row) and AttachmentFile (full path to each split 7z file)
• Save the spreadsheet as a CSV file
• Use Outlook’s Quick Steps feature to create a "New Email with Attachment" step, then pair it with Outlook’s mail merge via Word: Insert the attachment path as a merge field, and use Outlook’s macro-free attachment merge functionality (some versions require enabling the Developer tab to access this, but no coding is needed)

Important Notes #

• Double-check that each split 7z file is under your email provider’s attachment size limit (most providers cap at 25MB per attachment)
• Include clear instructions in your email body: Tell the recipient how many split files to expect, and how to merge them (e.g., "Download all files, then right-click the first .part001.7z file and select 'Extract Here' with 7-Zip to combine the full file")
• Add a numbered identifier in the subject line (e.g., "Split File 1/45: archive.part001.7z") to help the recipient organize the files
