In plain words
- We only email shop owners and staff, never the customers who join a line.
- Every email we send today is about your account or your shop: sign-in codes, the trial link you asked for, receipts and service notices.
- We send no marketing email. If we ever do, it will be only to people who said yes, with a one-click unsubscribe.
- We never buy email lists and never give your email to anyone for their marketing.
Who gets email from us
Only shop owners and staff, at the address they sign in with. Customers who join a line give no email address and never get email from Walk-In Waitlist.
The emails we send
| When | From | |
|---|---|---|
| Sign-in code | Every time you ask to sign in. The 6-digit code expires after 10 minutes. | Walk-In Waitlist, through our email provider |
| Trial link | When you ask the app to send you the link to start the free trial on the website | Walk-In Waitlist |
| Receipts and invoices | After each payment, and when a payment fails | Stripe, on our behalf |
| Billing notices | About your trial, a failed payment or a price change | Walk-In Waitlist or Stripe |
| Service notices | Changes to these policies, security matters, changes that affect your shop | Walk-In Waitlist |
| Texting registration | Carriers may ask the business contact to confirm the registration by email | Our texting provider or The Campaign Registry |
These are transactional or relationship messages: you get them because you have an account or a shop, and you cannot unsubscribe from them while you keep the account. Delete the account to stop them (see Delete your account).
Each owner email ends with how to reach us and a link to the Terms of Service.
No tracking in our emails
Our emails are plain text or simple formatted text without images. We do not add tracking pixels and we do not track whether you open them or click their links.
Marketing email
We do not send marketing email today. If we start (for example product news or tips), we will:
- send it only to people who chose to receive it;
- identify it as an advertisement or promotional message where the law requires;
- include our postal address and a clear way to unsubscribe with one click in every message;
- honor unsubscribes within 10 business days, and keep honoring them;
- never use misleading subject lines or sender names.
This follows the US CAN-SPAM Act.
Lists and sharing
We do not buy, rent or sell email lists. We do not share your email address with anyone for their own marketing. Our service providers handle email only to deliver it for us (see Subprocessors).
Who delivers our email
- Resend delivers sign-in codes and owner emails.
- Stripe sends receipts and invoices.
- Supabase, our database and sign-in provider, creates the sign-in codes.
Phishing
We will never ask for your sign-in code, card number or password by email, text or phone. Only enter your code on our own sign-in page. Forward anything suspicious to our support email (coming soon).
