Why this happens
Addo Sign automatically handles large files to ensure reliable email delivery. If attachments exceed 15 MB, the system converts them into a download link instead of attaching them to the email. Smaller files are sent as attachments as usual.
What users should know
If the total file size exceeds 15 MB, recipients will receive a download link.
The sending process is not blocked — the system automatically adjusts delivery.
Senders should inform recipients that they will receive a link instead of attachments.
⚠️It is not possible to determine the total size of your documents in advance. When signatures are added, the documents increase in size, and the final size also depends on the number of signers.
💡Tips for sending large documents:
Check file sizes before sending.
Split large documents into smaller PDFs under 15 MB if attachments are required.
Communicate with recipients that files may be delivered via a download link.
Remember that this behavior is automatic and cannot currently be changed.
Why this matters
Sets correct expectations for senders and recipients.
Reduces confusion about missing attachments.
Helps avoid unnecessary support requests related to email delivery.
✅Summary
When users upload documents with a combined file size greater than 15 MB and select email distribution, the system automatically sends a download link instead of attaching the files.
Users should be aware of this behavior before sending to avoid confusion.
