What you can do by email¶

You run your Mission Broadcast site by sending email — no website to log into, no app to install. Each command is just an email sent to a special address at your mission's domain.

Throughout this page, replace <your-domain> with your mission's address. That's either:

your custom domain — for example eldersmith.com, or
the shared subdomain — <your-slug>.missionbroadcast.com.

Write something in the message — don't send a completely empty email

Put a word or two in the subject and the body: "subscribe", "help", anything at all. Some mail providers — Google Workspace among them — refuse to send a message with an empty body, and it never reaches us. What you write doesn't matter; we go by the address you sent to (except for the few commands below that say otherwise). The links we email you already fill this in for you.

Not sure which commands you can use? Email help@

Send a short email to help@<your-domain> and you'll get a reply listing every command available to you. Some commands are limited to approved senders (the addresses your family set up), and the help reply only shows those if you're sending from an approved address.

Send a letter¶

Send to	`letters@<your-domain>`
Who	Approved senders only

Write your letter as a normal email and send it to letters@<your-domain>.

The subject becomes the letter's subject line.
The body becomes the letter. Basic formatting is kept.
Photos and attachments ride along — they're resized and included.

What happens next depends on how your family set things up:

By default, the letter lands in the Pending queue for a parent to review and broadcast.
If they turned on auto-relay, the letter broadcasts to all subscribers immediately.

Only approved senders can send letters

Your own email address (the one set as your Direct email in Site Settings) always works — send from it and your letter goes through. Mail to letters@ from any other address that isn't an approved sender gets a polite bounce-back. If someone else needs to send on your behalf (a parent relaying letters, say), ask the parent or admin to add that address in Site Settings → Approved senders.

Manage the subscriber list¶

Send to	`subscribe@<your-domain>`
Who	Anyone

The sender's email address is added to the list (or re-activated if they'd unsubscribed). They get a confirmation reply.

Unsubscribe¶

Send to	`unsubscribe@<your-domain>`
Who	Anyone

The sender is removed from the list and gets a reply explaining how to resubscribe if they change their mind.

Get your current subscriber list¶

Send to	`subscriber-list@<your-domain>` (also `subscribers@`)
Who	Approved senders only

You'll get a reply with your current roster — names, emails, and the date each person subscribed. Handy when you want to see who's following along but can't get to the console.

Add many subscribers at once¶

Send to	`bulk-subscribe@<your-domain>`
Who	Approved senders only

Attach a CSV file with Name and Email columns and send it. Everyone in the file is added in one go.

Get the archive link¶

Send to	`archive@<your-domain>`
Who	Anyone

You'll get a reply with a sign-in link to the letter archive — useful to share with a subscriber who's having trouble finding it.

See the letter designs¶

Send to	`themes@<your-domain>`
Who	Anyone

You'll get a reply showing every letter design you can choose from — each with a little preview picture and a note about what makes it special (for example, which designs show the photos you attach to a letter). To actually switch designs, open Account → Email Design and pick one.

help@ names your current design

A short email to help@<your-domain> tells you which design your letters use right now and points you here to see the rest.

Update the mission map¶

See your current pins¶

Send to	`list-locations@<your-domain>`
Who	Approved senders only

You'll get a reply listing your current map pins, numbered in the same order they appear on the public map.

Add or replace a pin¶

Send to	`update-location@<your-domain>`
Who	Approved senders only

Put an address or place name in the body of the email — for example, "Missionary Training Center, Provo, Utah" or a street address. We look up the coordinates and add a new pin to the map.

To replace an existing pin instead of adding a new one, tell us which number:

Put the pin's number on the first line of the body, or
Put ## and the number in the subject — for example, ##3.

Use ##3 in the subject, not #3

A single #3 is too common in normal subjects ("Week #3 in Brazil"), so it won't trigger a pin replacement. Use the double-hash ##3 form, or just put the number on the first line of the body.

Weekly writing prompts¶

If you've turned on the weekly writing prompt email (in Account → Site Settings), you'll get a short note once a week — the evening before your preparation day — with a couple of ideas to spark your letter home. Every one of these emails has links you can tap to change things, but you can also just send these commands yourself.

Get a different prompt now¶

Send to	`new-prompt@<your-domain>`
Who	You (approved senders)

Reply to your weekly email, or send a short email to new-prompt@, and we'll send back a fresh idea right away — handy when the week's prompt doesn't fit.

Change your preparation day¶

Send to	`set-p-day@<your-domain>`
Who	You (approved senders)

Put a weekday in the body — for example, Thursday. We'll time next week's prompt to arrive the evening before.

Change your letter design¶

Send to	`set-design@<your-domain>`
Who	You (approved senders)

Put a design name in the body — for example, Postcard. Not sure of the names? Email themes@<your-domain> first to see them all with previews.

Update your area / location¶

Send to	`set-location@<your-domain>`
Who	You (approved senders)

Put your new city and country in the body — for example, Lima, Peru. We look it up and, quietly, use it to figure out your local time zone so the weekly prompt still lands the right evening.

Change which prompts you get¶

Send to	`set-prompts@<your-domain>`
Who	You (approved senders)

Reply with story, come-follow-me, or both to choose which kinds of prompt idea your weekly email includes. both is the default — a mission-experience prompt and one tied to that week's Come, Follow Me reading.

Turn the weekly prompts off¶

Send to	`stop-prompts@<your-domain>`
Who	You (approved senders)

Send a short email and we'll stop the weekly prompt email. You can turn it back on any time in Account → Site Settings.
