Sign-up and invitations

On Create an account, a person sees:

• In waitlist mode, a link with your address opens the account form at once: the approval email's link and an invitation link.
• In waitlist mode, the link at the bottom of the Sign in page reads Join the waitlist, not Create an account. It opens the same page. After a failed sign-in, the page also shows "No account yet? Join the waitlist".
• In waitlist mode, if you create an account with an address the Sequential team has not approved, Sequential puts you on the waitlist instead, with your name and email. It never keeps the password. The page says "You haven't been let in yet, so we've added you to the waitlist. We'll email {your address} when you're in."
• If Sequential cannot add you, the page says "You haven't been let in yet, and we couldn't add you to the waitlist just now. Try again in a moment.", with a Join the waitlist link. After too many tries from one network, it says "You haven't been let in yet. Too many waitlist attempts from here: wait a few minutes and try again."
• In invite mode, the waitlist page shows only "Sign-up is by invitation only."
• In open mode, the waitlist page opens Create an account instead. If the link had your address in it, the form keeps it.
• From 15 October 2026, if Sequential cannot check the sign-up mode, the page has the title Sign up, the line "We can't check whether sign-up is open right now." and Retry, and no form. If Retry also gets no answer, it adds "Still no answer. Sequential may be down. Wait a few minutes."
• In every mode, Sequential limits how many accounts are created each day: per network address, per email domain and in total. An invited address skips the first two. See Limits.
• Over a limit, the page says which one: "Too many accounts were created from this network today. Try again tomorrow.", "Too many accounts were created for this email domain today. Try again tomorrow, or ask a teammate to invite you." or "Sign-up is busy right now. Try again later." If Sequential cannot check the limits: "Sign-up is temporarily unavailable. Try again in a minute." A refused Continue with Google shows the same message on the Sign in page.

• After you join, a confirmation email, "You're on the Sequential waitlist", follows.
• When the team approves you, you get the email "You're in: create your Sequential account". From 11 October 2026, an account that you create from its link, with that address, needs no verify email. The link proves the address for 7 days.
• The optional fields are Name, Company, Role, What do you use today? and Anything we should know?.
• If you join again with the same address, you keep your place. Sequential fills in only the details you left blank. It sends no second email.
• After a join, this browser remembers it, in its local storage (sq-waitlist-joined). It keeps only the first character of the address, the domain and the day, for example a…@example.com. It never keeps the full address. This also occurs when Sequential puts you on the waitlist after you try to create an account.
• When you come back in the same browser, the form shows You're on the list and "You joined as a…@example.com on 9 Oct 2026. We'll email you when you're let in." On the sign-up page, Already let in? Create your account stays below it.
• To join with a different address, select Use another email. The browser forgets the join and shows the form. A link with an address in it, such as the approval email's link, always shows the form.
• The form gives the same answer for every address. So it never shows whether an address is already on the list or already has an account.
• After approval, the sign-up page shows the subtitle "You're in. Create your account."
• Approval is not an invitation to someone else's organisation. After you create your account, you set up your own.
• The Create your account link in the approval email carries no secret. Sequential lets you in because your address is approved.
• If you lose the email, go to the sign-up page. Open Already let in? Create your account and fill in the form with the same address.
• Approval has no time limit.
• Sequential sends no email if the team declines a request.

• After you verify, you set up your organisation. If you came from an invitation, you go back to the invitation.
• If you try to sign in with your password before you verify your address, Sequential opens the Verify your email page.
• The Check your inbox page has Resend the link and Use a different email.
• After each send, wait 30 seconds before you send the link again.
• The Verify your email page has the same Resend the link button.
• If the link expired, or you copied only part of it, the page explains what went wrong. It lets you send a new link.
• After you verify your address, the link does not sign you in again. Sign in with your password.
• From 11 October 2026, a completed password reset also verifies your address. If you cannot find the verify email, click Forgot password? on the sign-in page and reset your password. See Two-factor authentication and account security.

From 15 October 2026, the sign-up, sign-in, waitlist and invitation pages on www.usesequential.com, and the two-factor setup, send Sequential's own product events to Sequential's own project:

• signup_viewed: where you came from, the sign-up mode, and whether the page showed the form, the waitlist, or that it could not check whether sign-up is open
• signup_field_started: the name of a field, such as email, once per field. Never what you type
• signup_submitted: that the form was sent, with a password
• signup_refused: the error code of a refused sign-up only. A server error sends nothing
• account_created: how the account was made
• waitlist_joined: where you came from only. It comes from the waitlist form, and from a sign-up that Sequential puts on the waitlist
• signed_in: that you signed in with a password, and whether Sequential asked for a two-factor code
• sign_in_refused: the error code of a refused sign-in only. A server error sends nothing
• two_factor_enabled: that your first two-factor code was confirmed
• invite_accepted: the role of an accepted invitation only. Never the organisation, the person who invited you, or your email
• feedback_sent: from 16 October 2026, the number of a feedback item after Sequential accepted it, from any page of the app. Never its text. See Send feedback to the Sequential team

The events hold no name, no email and no typed text. A page on the way to a claim link, a reset link, an OAuth page or a staff page sends nothing, and neither does a page opened with an email's proof link (#m=). Nothing is sent while Sequential staff view the app as a customer. A Google sign-in, an email verification and a password reset send no event from these pages.

• Continue with Google sits above the email form.
• The sign-up page has no Google button.

• The default Role is Member.
• You can also open Settings → Organisation from Organisation in the account menu.
• An example of the invitation email: "Ana invited you to join Acme on Sequential". The email says in one line what Sequential is. It ends with why you got it: "You got this mail because Ana entered this address. If you did not expect it, ignore it."
• From 13 October 2026, every email from the hosted Sequential ends with "Sequential · Help: support@usesequential.com". On a self-hosted server, the help address is MAIL_REPLY_TO. Without it, the email ends with "Sequential" only.
• In the invitation, Sequential removes links, email addresses, web addresses and IP addresses from the inviter's name and the organisation name. It cuts a name that is longer than 60 characters and ends it with "…". If nothing is left, the email says "A teammate" or "an organisation". The waitlist emails do the same with your name. They start with "Hi" and your name, or with "Hi there," if nothing is left. The verification and password reset emails start with "Hi," and contain no name.
• Roles and permissions shows what each role can do.
• The Audit log records invitations, joins and cancellations.
• Under the form, Sequential shows the description of the chosen role.
• Only an Owner can invite another Owner. Admins see the Owner option, but they cannot select it.
• An expired invitation shows an Expired badge.
• If an invitation has not expired, Resend keeps the same link and gives it a new 48 hours.
• If an invitation shows Expired, Resend sends a new invitation with a new link. The expired row stays in the list until you Revoke it.
• If you invite an address that already has a pending invitation, the new invitation replaces it. The earlier link stops working.

Pending invitations lists the open invitations. Each row shows the email, the role and when the invitation expires, for example "in 22 hours" or "in 2 days". Hover over it to see the exact time.

• Owners and admins also see Invited by. If that person left the organisation, it says "Removed member".
• To send the email again, select Resend.
• To withdraw an invitation, select Revoke. Then, at "Revoke this invitation?", select Confirm. Its link stops working, and "Invitation revoked" confirms it. Before 13 October 2026, the button was Cancel.
• Members and viewers see the list without Invited by and without buttons. They see the card only when there are open invitations.

A link is no longer valid if it expired, was cancelled or was already used. It is also no longer valid if the sender has left the organisation.

The page checks the link only after you sign in. If you are signed out, you see You have been invited, even for a link that is no longer valid.

If sign-up is not open, Sequential refuses Create account from a link that is no longer valid.

• After your first sign-in, if you belong to no organisation, Sequential opens setup.
• Set up your organisation asks for an Organisation name and a Slug. The slug is a short handle made from the name.
• A slug uses lowercase letters, digits and single dashes, up to 60 characters.
• The slug must not belong to another organisation. If it does, you see "That slug is already taken. Try another one."
• You cannot change the slug later.
• You become the organisation's Owner.
• Setup then moves on to your first project, the install step and the agent step. The agent step is optional. Your first hour walks through them.
• You can set up another organisation only if you are a Member or Viewer in every organisation you belong to. To do it, go to /onboarding.
• If you are an Owner or Admin anywhere, the dashboard gives you no way to create a second organisation.

• To switch to another organisation, select one of its projects in the switcher.
• An organisation with no projects, or only archived ones, shows No projects yet. You cannot switch into it.
• The switcher lists every organisation you belong to, your role in each, and its projects.
• When you belong to more than one organisation, the switcher shows the current organisation's initials beside the project name.
• Settings → Organisation always shows the organisation of the selected project.
• An organisation with no unarchived projects has no project to select. If you have an unarchived project in another organisation, you cannot open the empty one in Settings → Organisation.
• So you cannot rename that organisation, invite people to it, leave it or delete it.

• To leave, select Leave organisation. Then select Leave [organisation name], or select Stay.
• If you are a Member or Viewer, neither the settings tabs nor the account menu show Organisation. To find Leave organisation, go to /settings/organization.
• Deleting an organisation removes the organisation, its members, invitations, projects and ingest keys, and its audit log.
