There are two main ways that the LuckGrib Offshore weather service can deliver its data: email or a more direct method using a low speed internet connection. Since the majority of offshore sailors have figured out some way of sending and receiving email, email delivery of LuckGrib Offshore weather data may end up being the most commonly used method.
There are a lot of ways an offshore sailor can arrange to send and receive email while operating remotely.
On the hardware side, there is HF radio (such as Icom 802/Pactor 3), satellite phone, satellite wifi hotspots (such as Iridium Go!) and satellite broadband. Each of these approaches has a different set of benefits and tradeoffs. If you choose to use HF radio, there are a number of radios and modems that are suitable. If you choose a satellite phone, there are devices from Iridium, Globalstar, Inmarsat, Thuraya and others. There are also a number of satellite broadband devices. That’s the hardware side of things - its a complex world.
On the software side, once you have your hardware setup you will need to choose an email service. If you are using HF radio you will likely go with Sailmail. If using any of the the other satellite devices you have a choice of email service, such as:
LuckGrib does not have any preference for who you choose as your email service provider, that’s all up to you.

LuckGrib can be setup to use email as the delivery mechanism for Offshore Compact files through a setting in the application Preferences / Settings area. After you set email as your preference, you will see a slightly different GRIB request interaction.
There is a tutorial available which discusses the email option in much greater detail.
Here is a sample of the email message you can expect when you use this service:
To: s/v Your Beautiful Vessel <email@example.com> From: firstname.lastname@example.org Subject: SouthPacific.20190224.12.1854.grb Thanks for using the LuckGrib Offshore email service. The original GRIB file was: 55,021 bytes The Offshore compact file is: 16,925 bytes, saving 38,096 bytes (69%) The file was created in 0.185 seconds --- Note that the file provided is NOT a GRIB file. Import this file into LuckGrib to view it. For more information, see: offshore.luckgrib.com [File attachment here]
Some offshore email systems use a white list concept to reduce the amount of email that you receive. This can be used to forbid anybody sending you email that you do not previously approve.
An example of a system which supports this is winlink.org
If you are using a white list facility, you will need to add the LuckGrib email address to the white list BEFORE sending your first email request.
The email adddress to white list is: email@example.com
While you are updating your white list you may also want to add the LuckGrib email address, to allow me to contact you: firstname.lastname@example.org
Note: If your email system uses white lists and you have not added the LuckGrib email address to it before sending an email request, then the message that the LuckGrib server tries to send to you will bounce. Once the mail system detects an email address which is inoperative, it is banished from the system, and all future attempts to send to it are suppressed.
If you are sending email requests and are not receiving replies, please contact me, and I can look into it. (A more automated way of deailing with this would be nice, and will be looked at as a future update.)
There is a short note for people who use Apple iCloud email.
