Attachments (optional)

Add photos or documents PDF, photos, Word or Excel · up to 3 files, 4 MB each

What you can attach

Files go with your message to our orders inbox. Limits match Amazon SES and Zoho Mail so the note is not bounced or stripped.

Allowed

PDF
JPG / JPEG
PNG
WebP
GIF
HEIC (iPhone)
Word (.doc, .docx)
Excel (.xls, .xlsx)
CSV / TXT

Size

Up to 3 files
4 MB per file
7 MB combined — SES encodes attachments (~33% larger) and caps a message at 10 MB

Not accepted

Programs and scripts (.exe, .js, .bat, .msi, .dll, .ps1, .html, .svg)
Archives (.zip, .rar, .7z) — they are a common malware path and Zoho often strips them
CAD / takeoff packs (.dwg, .dxf) — send those through Quote Center

A security check runs before send. Uploads are not stored on the website — they travel only as email attachments, then are deleted.
