After creating a form in OmniForm, saving it as a mailable Filler (EXE), and sending it via email; recipients of this e-mail are unable to receive them.
When sending and attaching files, recipients may not be able to receive Self-Executing Files (EXE) or the file may be too large. Recipients may also have a block on *.EXE files, which was put in place to prevent potential viruses.
Have the recipients check with their Internet Service Provider to determine if they have a limit on file size or type that they can receive. If they have not limits or constraints, it is also best to check with your own provider.
If the files are ultimately too large, it would be best to reduce the number of page in the form. Reducing the number of pages and splitting it into different parts will reduce the file to a size that can be sent via e-mail.
If the Internet Service Provider, has block the distribution of *.EXE files, it may be easier to post the form to eOmniForm.com. This will allow you to share the form in HTML format via a web link.
