Who can do this: Owner or Admin
Each Letterloop can have up to 50 total members, including the Owner, Admins, Contributors, and Readers. The create screen says Group works best for 3-10 people; that recommendation is separate from the 50-member cap. Some current iPhone, iPad, and Android subscription screens still say there is no fixed member limit. That mobile message is outdated; the enforced limit is 50 members. A current account-level plan covers all members across every Letterloop that account owns. Legacy plans are different: an older Letterloop-specific subscription or Lifetime plan covers only its sponsored Letterloop. A larger roster can still create more administration, email, and reply activity, so set roles deliberately.
Use Group when many people should contribute responses.
Use From You when one Owner writes and everyone else should receive the finished Issue as Readers.
In Group mode, make occasional participants Readers when they should receive Issues without reply reminders.
Add a small number of trusted Admins to share member, schedule, reminder, and customization work.
At 50 members, web shows Member limit reached (50) and disables the add-member control. A new invite-link join or mobile add attempt cannot create a 51st member. Remove someone who no longer needs access before adding another person.
Add people directly when you need to verify each name, email, and role.
Use the Contributor and Reader invite links only with the intended audience.
Treat every invite link as a bearer link: anyone who receives it can use it to join with that role.
Add an invitation note explaining the purpose, expected cadence, and who to contact for help.
Plan for Letterloop's automatic seven-day reply window; current schedule options do not include a separate reply-window setting.
Use automatic reminders and send a manual reminder only to Contributors who have not replied.
Use Issue progress to identify missing responses instead of messaging the whole roster.
Keep question and Section counts focused so the Issue remains easy to complete and read.
Use the Album, response filters, and PDF export to navigate a media-heavy or response-heavy archive.
Contributors are included in the reply window and can receive reply reminders. Readers receive delivered Issues without being asked to contribute. Owners and Admins can use reply progress to follow up only with Contributors who have not replied. The roster cannot grow beyond 50 members; after a member is removed, an Owner or Admin can use the available place for someone else.
Review the roster regularly and remove access that is no longer appropriate. Delivered Issues can also be accessed by people who receive forwarded email content or a valid share link, so remind members to keep invitation and Issue links private.
