How to Send Large Video Files via Email as Attachments

You've finished editing a client video — 150MB of polished footage — and need to email it over. Gmail bounces it. Outlook rejects it. You try WeTransfer, but your client can't figure out the download page. You upload to Google Drive and share a link, but it gets blocked by their corporate firewall. Sound familiar?

SendSplit delivers video files up to 200MB as real email attachments. No cloud links, no download pages, no accounts required. The video arrives directly in the recipient's inbox — as a file they can save, forward, or open immediately.

Why Email Rejects Large Video Files

Video files are large by nature. A single minute of uncompressed HD footage can easily exceed 100MB. Even compressed MP4 exports for client review often run 50MB–150MB. Email providers were never designed for this:

  • Gmail — 25MB limit; anything larger automatically converts to a Google Drive link
  • Outlook — 20MB limit; files above this are rejected or pushed to OneDrive
  • iCloud Mail — 20MB limit; large files use Mail Drop with a 30-day expiry link
  • Corporate email — often capped at 10MB by IT departments

The result: video files almost never travel as real attachments. They get turned into links, uploaded to third-party platforms, or compressed until they're unwatchable.

The Problem with Cloud Links for Video

Sharing a Dropbox or Google Drive link for video delivery creates friction every time:

  • Requires an account — clients are prompted to sign in to Google or Dropbox before downloading
  • Links expire — WeTransfer links disappear after 7 days; Mail Drop after 30 days
  • Blocked by firewalls — corporate clients often can't access external cloud services
  • No delivery confirmation — you don't know if the recipient actually received the file
  • Can be forwarded — your video link can spread beyond the intended recipient

How SendSplit Delivers Video via Email

SendSplit splits your video into email-sized parts and delivers each part as a real attachment. The recipient's email client receives standard attachments — no plugins, no cloud accounts, no download links to click.

  1. Open sendsplit.com/upload-to-send in any browser
  2. Upload your video file (MP4, MOV, AVI, MKV, WebM — up to 200MB)
  3. Choose a split size: 10MB, 20MB, or 25MB based on the recipient's email provider
  4. Enter the recipient's email address
  5. Click send

SendSplit compresses and splits the video, then delivers each part as a standard email attachment via SMTP. The recipient downloads all parts and extracts the original video file — full quality, no re-compression, no links to click.

Who Needs to Email Large Videos?

  • Video editors and agencies sending client review cuts, final deliverables, and raw footage excerpts
  • Marketing teams distributing campaign videos, ad creatives, and product demos to media buyers
  • Real estate professionals emailing property walkthrough videos to clients and listing agents
  • Training and L&D teams sharing instructional videos, onboarding recordings, and course materials
  • Journalists and media sending B-roll footage, interview recordings, and news clips to editors
  • Legal teams transmitting deposition recordings, surveillance footage, and digital evidence

Tips for Emailing Video Files

  • Export at delivery quality, not edit quality — for client review, H.264 MP4 at 10–20Mbps is usually sufficient and keeps file size manageable
  • Use 20MB splits for Gmail recipients — this keeps each part well under the 25MB limit and avoids spam filter triggers
  • Use 10MB splits for corporate recipients — corporate Exchange servers are often configured at 10MB; when in doubt, use the smallest split size
  • Tell the recipient to expect multiple emails — let them know they'll receive several emails with attachments and that all parts are needed
  • Add password protection for confidential footage — for unreleased product videos, legal evidence, or sensitive content, enable SendSplit's optional password encryption

Stop fighting with cloud links and WeTransfer expiry dates. Try SendSplit — send video files up to 200MB as real email attachments, delivered directly to any inbox. No accounts. No links. No expiry.
