Email Notifications

Every email 5-by-5 sends, who receives it, and how to make sure they don't end up in spam.

Overview

5-by-5 sends transactional emails for the things that matter most — invitations, invoices, payment receipts, maintenance squawks, password resets, and onboarding tips. This page lists every email type, who receives it, and the email address it comes from so you can allow-list the sender and stop missing important messages.

Email Senders

All 5-by-5 emails come from one of these addresses on the blueskyapplications.com domain:

Add all six to your contacts to be safe.

Email Types

Account & Authentication

Email verification — sent when you create an account or change your email address. Click the link inside to confirm the new address.

Password reset — sent when you tap “Forgot Password” on the sign-in screen. Contains a one-time link to set a new password. Links expire after 1 hour.

Group Membership

Invite to join a group — sent when an Owner or Admin invites you to a flying club or partnership. Contains an invite code and instructions for joining.

Billing & Payments

Monthly invoice — sent to every member when bills are posted for the month. Contains the line-item breakdown of their monthly charges (flight time, fixed share, shared expenses, tax) plus a payment link that opens Stripe Checkout for ACH or card payment. See Online Payments for the full payment flow.

Payment receipt — sent when a payment settles successfully. For card payments this arrives within seconds; for ACH it arrives once the bank confirms the transfer (typically 3-5 business days).

ACH payment initiated — sent immediately when a member authorizes an ACH payment. Acknowledges that the payment is in flight and explains the 3-5 business day settlement window so the member isn’t left wondering whether it went through.

ACH payment failed — sent if an ACH transfer bounces (insufficient funds, account closed, etc.). The member is notified directly so they can retry, and every Owner and Admin in the group is BCC’d so the treasurer can follow up promptly.

Subscription confirmations — sent when you upgrade, change billing periods, or update your payment method on the 5-by-5 subscription itself. These come from Stripe directly.

Maintenance

New squawk alert — sent when any member reports a squawk. The To: line goes to every member with a Mechanic role or Maintenance Officer title. Every Owner and Admin in the group is BCC’d so the alert doesn’t fall through the cracks if the mechanic is away.

The email includes the severity (Grounding / Monitor / Minor), the description, the reporter’s name, the aircraft tail number, and a link back to the maintenance screen. Severity drives the color of the email header — red for grounding, orange for monitor, amber for minor — so urgency is visible at a glance.

If a group has no mechanic and no one with “maintenance” in their title, the alert routes directly to Owners and Admins instead.

See Squawk Reporting for how squawks are filed and resolved.

Product & Updates

Welcome series — eight emails sent over your first three weeks, walking through the app one feature area at a time. The schedule is roughly every 2-3 days starting on signup day: Welcome → aircraft/group setup → your first flight → maintenance, squawks & documents → then a tour of each web-dashboard tab in turn (Overview, Flights, Finances, Maintenance). The early emails (setup and first-flight) are tailored to whether you’re on a Solo or Club plan. Sent only if you’ve kept the welcome series enabled in Settings → Communications (on by default).

Product updates — periodic emails about new features, tips, and getting more out of 5-by-5. On by default — opt out in Settings > Communications.

Partner promotions — occasional emails about deals or partner offers we think you’d find genuinely valuable. Off by default. We do not sell your data; opt in via Settings > Communications if you’d like to receive these.

Keeping 5-by-5 Emails Out of Spam

The first email from any new sender almost always lands in spam, especially in Gmail. Here’s how to fix it permanently for each major email provider.

Gmail (Web)

1. Open the Spam folder in the left sidebar
2. Find any 5-by-5 email (sender ends in @blueskyapplications.com)
3. Open the email and click Not spam at the top
4. Click the sender’s name → Add to contacts
5. Optional but recommended: create a filter — click the search bar’s filter icon, enter from:@blueskyapplications.com, click Create filter, check Never send to Spam, then Create filter

Gmail (Mobile)

1. Open the Gmail app
2. Tap the menu (☰) → Spam
3. Tap a 5-by-5 email
4. Tap the ⋮ (more) menu → Report not spam
5. Tap the sender’s avatar → Add to contacts

Outlook / Office 365

1. Open the Junk Email folder
2. Right-click a 5-by-5 email → Junk → Never block sender’s domain
3. Right-click again → Add to Safe Senders

Apple Mail (iCloud)

1. Open the Junk mailbox
2. Tap a 5-by-5 email
3. Tap the sender → Add to VIPs (or just Add to Contacts)
4. Move the email to your Inbox — Apple Mail uses this signal to train its spam filter

Yahoo Mail

1. Open the Spam folder
2. Open a 5-by-5 email
3. Click Not Spam
4. Click the sender’s name → Add to Contacts

Reducing Notification Volume

If 5-by-5 is sending more email than you’d like, two settings shape the volume:

Settings > Communications (mobile) — toggle product tips and partner promotions on or off. Transactional emails (invoices, receipts, squawk alerts, invites) cannot be disabled — they’re required for the product to function.

Squawk alerts — these are routed by role and title, not by personal opt-in. If you’re receiving them and don’t want to, ask the group Owner to either change your role from Mechanic to a non-maintenance role, or remove the Maintenance Officer title from your member record. Both changes are made by an Owner or Admin on the Members tab — there’s no self-service toggle, because the whole point of these alerts is that they reach the people responsible for fixing the issue.

What 5-by-5 Does Not Do

• We do not send marketing emails to non-customers
• We do not share your email address with third parties
• We do not send “your subscription is expiring” pressure emails — if your card expires, you’ll get one calm notice from Stripe, not weekly reminders
