Why Email Attachments Have a 25MB Limit
Gmail, Outlook, and most email providers restrict attachment size — but that doesn’t mean you’re stuck.
Most email services limit attachments to about 25MB. When your file is larger, you’ll see errors like “Attachment too large” or “File exceeds size limit.”
SendSplit automatically splits large files into smaller parts and sends them as real email attachments. Your recipient receives the files directly in their inbox — no cloud links, no extra steps.
