My co-admin got the email and I didn't.

Two things differ per person: the Just for you mute on Dashboard → Notifications (yours only), and Managed by on the sheet — a managed sheet emails its manager and the account owner, not every admin. Check both; everything else about the setting is shared.

When does a daily or weekly roundup arrive?

In the morning, US time — daily ones every day, weekly ones on Mondays. A roundup lists every sign-up since the last one, with the same detail an instant email carries, plus anyone who gave a spot back. A form with nothing new sends nothing at all.

I switched a form to a roundup and the sign-ups from before didn't show up in it.

That's by design. Switching starts the clock then and there, so the first roundup covers what comes after it rather than replaying sign-ups you already got one by one.

Do I get an email when I add someone myself?

No. You added them, so there's nothing to tell you. The volunteer still gets their confirmation (if they have an email), and the sign-up still syncs to your ChMS and counts on the dashboard.

Do I hear about cancellations?

Yes, through the same setting: an instant form emails you when someone cancels, and a roundup form lists cancellations in the next roundup. A spot given back by someone you removed yourself isn't reported — you did it.

Can I get sign-ups in Slack instead?

On Pro, each form can post its new sign-ups and cancellations to a Slack channel you pick, whatever the email cadence. See Send sign-ups to Slack.

I didn't get the email when someone signed up

Every admin email and where it's controlled is laid out in Emails & notifications. This is the short path for the moment one didn't arrive.

The short answer: The sign-up email is decided in three places: the sheet's own New sign-up emails setting (which can be off or a daily/weekly roundup), the account-wide default on Dashboard → Notifications, and your personal Just for you mute. On a sheet with Managed by set, only the manager and the owner are emailed. Sign-ups you add yourself never email you.

Check these, in order

The sheet's own setting. Open the sheet, Settings tab, New sign-up emails. It can follow the account, be off for this sheet only, or be a daily or weekly roundup — in which case nothing arrives at the moment of the sign-up; it comes in the next roundup.
The account-wide default. Dashboard → Notifications sets what every sheet does unless it overrides. If it's off or on a roundup there, every sheet that follows the account behaves that way.
Your personal mute. The Just for you card on Dashboard → Notifications silences the sign-up and cancellation emails, the Monday summary, or both — for your login only. Your fellow admins aren't affected, which is why they may have the email and you don't.
Managed by. If the sheet's Settings tab names a manager, its sign-up emails, cancellation notices, roundups, and spots-still-open heads-up go to that manager and the account owner only. Set it to nobody to email every admin.
Who signed them up. People added from the Slots tab, keyed in from a clipboard, or moved between spots by an admin don't trigger the email — it's for sign-ups that arrive from the public page or embed.
Spam or a filter. The email comes from SignUpChurch with the volunteer as Reply-To, which some filters find unusual. Look in spam, and add our sending address to your contacts; it's listed in Is this email really from SignUpChurch?.

The other admin emails, and when they come

“Your sheet is full” — once, the moment the last limited spot is taken. Follows the same sign-up email setting.
Spots still open — about three days before the event when limited spots remain, once per sheet, only while the sheet is open for sign-ups.
Monday summary — Monday morning, US time, only when there are live sheets or last week's sign-ups to report. Its own switch is on Dashboard → Notifications.
ChMS sync issue — sent to every admin whenever a provider reports a problem, ignoring mutes, because a broken integration isn't a preference.

Nothing is lost when an email doesn't arrive. Every sign-up is on the sheet's Sign-ups tab the moment it happens, and the dashboard counts it.
