Sending attachments to a mailing list
Photos and files go out with list email, up to 25 MB per message.
Attach photos and files to an email the way you normally would and they go out to the list with your message.
The limits
| Limit | Value |
|---|---|
| Total size of all attachments | 25 MB |
| Number of files | 20 |
The 25 MB is the total across every file, not per file. Six photos at 5 MB each is 30 MB and will not go out.
If your message can't be delivered
If you go over a limit, nothing is sent — the message doesn't go out to the list with the files quietly missing. You get an email back titled "Not delivered:" followed by your subject line, saying which limit you hit.
This reply only goes to people the troop recognizes. If you email a list from an address that isn't on your MyTroop account, there's nothing to reply to. Adding that address as a backup email fixes it.
What to do with something too big
- Send fewer photos per email. Two or three messages instead of one usually does it.
- Share a link instead. Upload to Google Drive, Dropbox, iCloud, or your phone's photo-sharing, and paste the link. This is the better option for a whole weekend of photos — it also spares everyone's inbox.
- Ask an admin to post them to an album. Photos attached to an event or an album page stay findable later, which an email thread doesn't.
Sending from an address the troop doesn't know
If a list is set to accept mail from anyone (a "contact us" style address), a message from a stranger still reaches the troop — but any files attached to it are held back, and everyone sees a note saying so. Only people the troop recognizes can send files to families.
If that's happening to you and you are a member, it means you emailed from an address MyTroop doesn't have for you. Add it as a backup email and attachments will go through.
Files that can't be sent at all
Programs and scripts — .exe, .bat, .jar, .vbs and similar — are refused no matter how small they are. Most email providers block these outright, and a single one would stop the whole message reaching anybody.
Web pages are refused too — .html, .svg and similar. Those aren't blocked by providers, but a web page arriving from your troop's own address is exactly what a convincing scam looks like, so MyTroop doesn't pass them on.
Either way you'll get the same "Not delivered" reply naming the file.
Why a photo in your signature doesn't show up
If your email signature has a logo in it, it won't be attached to the message that goes out to the list. MyTroop removes images from the body of forwarded messages — an image loaded from someone else's server can report back when each person opened the email, and a mailing list would hand that to whoever sent it. With the image gone from the body, a signature logo would otherwise arrive as a mystery file attached to every email you send the troop, so it's dropped too.
A photo you paste or drag into the body of the message is different — that does go out, as a normal attachment.
