If your booking alerts land in Gmail's Promotions tab instead of Primary, nothing is broken. The email was delivered. Gmail just filed it in a different part of your inbox.
Why Gmail sorts your email this way
Gmail is trying to be helpful. It reads the shape of each message and guesses where you would want it. A short, personal note from one person tends to land in Primary. A message with a business name in the from line, a logo, prices, and several links looks like a receipt or an offer, so it lands in Promotions.
That is why two emails from the same system can end up in different tabs. Your new lead alert and your new booking alert are not shaped the same way, so Gmail does not treat them the same way.
Gmail also learns from how people across its network handle similar messages, so its guess can shift over time even when nothing on your end changed.
Send every Check Cherry email to your Primary tab
Every email Check Cherry sends you comes from the same domain, checkcherry-mail.com. One filter covers all of it: your booking alerts, lead alerts, the Check Cherry Daily digest, payout notices, and billing receipts.
On your phone
You cannot build a filter in the Gmail app, but you can teach it. Open the email, tap the menu in the top right, and choose Move to, then Primary. If Gmail offers to do this for future messages from that sender, say yes.
Outlook and Apple Mail
- Outlook sorts into Focused and Other. Right click the message and choose Always move to Focused.
- Apple Mail on iPhone sorts into categories on iOS 18 and later. Use Categorize Sender on the message and pick Primary.
- Yahoo and others use similar views. Look for an option to move the sender to your main inbox.
Do not rely on email alone
Tabs, filters, and spam rules all belong to your email provider, and they can change without warning. If missing a booking alert would cost you, put a second channel behind it.
- Push notifications. The Check Cherry app alerts you the moment a client signs or a lead comes in, without touching email at all. See push notifications.
- Check Cherry Daily. A once a day summary of everything that happened in your account.
- Your dashboard. New bookings and leads show up there as soon as they happen.
If a client cannot find your email
That is a different problem, and you cannot set a filter inside someone else's inbox. Ask them to check their Promotions tab first, because the message is usually sitting right there. If it is genuinely missing, see why are my emails going to spam.
