Frequently Asked Questions

What target size should I choose for email?

For Gmail or Outlook: Under 5MB is usually fine. For corporate mail servers or strict portals: use Under 2MB to be safe. For job portals and government forms: Under 1MB is the safest choice. Use the Custom option if you know the exact limit.

My email was bounced saying "attachment too large" — what should I do?

Use the Custom target to set an exact size just below the bounce limit. For example if the bounce message says 5MB limit, set a 4.5MB custom target. Download and resend.
