To accommodate customers who experience difficulty accessing the World Wide Web, NGA provides a Subscription Service whereby the US Notice to Mariners (NTM) is delivered to the requesting e-mail address each week, with the following limitations:
Many networks and e-mail applications have restrictions on file sizes for e-mail attachments. In order to ensure all NTM files are received, the limit on file sizes for the receiving account should be changed to 2.5 Mb. User's may need to contact their system's administrator for assistance with this change.
Instructions to unsubscribe from the Service are included in each subscription e-mail.
