When Are Emails Sent from SignUp and What Do They Say?
A Guide to Every Automated Email SignUp Sends
Last Updated June 17, 2026
All SignUp emails come from mail@signup.com and display the Primary Organizer's name in the sender line. Participants receive individual notifications — email addresses are never visible to others. Replies route directly to the Primary Organizer's email.
Invitation Emails
Sent upon the Organizer's request. Subject line: "[SignUp Title]: Please sign up"
Confirmation Emails
Sent immediately when a participant selects a spot and clicks Save or Done. If a participant forgets to click Done, a confirmation sends automatically within 15 to 20 minutes. Subject line: "You are signed up for [SignUp Title] - THANKS"
Reminder Emails
Sent 1 to 7 days before assignments (default is 2 days). Organizers can customize timing and add a custom message in the Email Preferences under the Settings tab. Subject line: "[SignUp Name] - Reminder!"
Assignment Emails
Sent when an organizer manually assigns a participant. Notifications batch every 20 to 30 minutes, so multiple assignments send in one combined message. Subject line: "[SignUp Name] - Important Update"
Waitlist Notifications
Sent to participants who requested alerts when a spot opens. Subject line: "WAITLIST ALERT: Spots now available for [SignUp Name]"
Change Emails
Sent in batches after an organizer makes modifications. These can be toggled on or off. Subject line: "[SignUp Name] - Important Update"
What Organizers Receive
Organizers receive "echo" emails listing recipient names, contact info, any custom text, and delivery failure alerts. They also receive a Friday Status Preview each week — a summary of signups and open spots for the upcoming Sunday-Saturday period.
