What Is the Maximum Email Attachment Size on Hosticko? #
What counts toward the 50MB limit? #
The 50MB limit is not just the attachment file size. It includes:
- The email body (text + HTML formatting)
- All attachments combined
- Email “overhead” (encoding, headers, etc.)
Attachments are usually sent using encoding (like Base64), which can increase the size. So a “50MB file” can exceed the message limit after encoding.
Why emails fail even if Hosticko allows 50MB #
Even though Hosticko supports up to 50MB, many email providers and ISPs block large emails, often around 20MB.
That means your email can still bounce if the recipient’s server rejects it.
Best way to send large files #
Email was never designed for heavy file transfers. If you need to send big files, use a dedicated file transfer or cloud sharing service
and send the recipient a download link instead. :contentReference[oaicite:2]{index=2}
Recommended options #
- WeTransfer (simple link sharing)
- Dropbox
- Microsoft OneDrive
- Google Drive
Quick tips to avoid attachment problems #
- Compress files into ZIP/RAR to reduce size.
- Split files into smaller parts (e.g., Part 1 / Part 2).
- Send a link instead of an attachment for anything above 20–25MB (safer for recipients).
- Avoid embedding huge images directly into the email—attach them or use links.
FAQs #
Is the 50MB limit per attachment or per email? #
It’s per email message total (email content + all attachments together). :contentReference[oaicite:3]{index=3}
What should I do if I must send a file bigger than 50MB? #
Upload the file to a file-sharing service and send the download link instead (recommended for speed and reliability). :contentReference[oaicite:4]{index=4}
My file is under 50MB but still fails—why? #
The recipient’s email provider may have a smaller limit (often ~20MB), or the message grew larger after encoding.
Use a cloud link to avoid bounce errors.
