OpenNetworks CRM system is not allowing me to send my bulk mail.

There is a 500MB limit set on the bulk mail server, which prevents huge bulk mails being sent out.

Keeping emails small is polite email etiquette, and helps the web world move faster.

OpenNetworks has placed this limitation to alert us to clients sending large attachments - so we can assist them in converting their email message to a smaller and more effective HTML format.

Keeping emails small also improves the queuing speed of bulk emails, and minimizes bandwidth usage which increases costs all round.
