Tenant notices that actually get read
Rent reminders landing in promo folders. Maintenance updates lost in spam. Tenants claiming they "never got the notice." Sound familiar? Blasts gives your tenants a dedicated notification inbox they opted into — so every message lands where it matters.
The real cost of missed notices
Built for property operations
Rent Reminders
Automated 1st-of-month and 5th-of-month due notices. Fewer late payments, fewer awkward follow-ups.
Maintenance Updates
"Your work order #4521 is scheduled for Thursday 2-4 PM." No more "where's my repair?" calls.
Lease Notices
60-day and 30-day renewal alerts with PDF attachments. Legal compliance built into the workflow.
Emergency Alerts
Water shutoff, fire alarm testing, severe weather. Time-sensitive notices that can't wait for email.
Community Updates
Pool hours, parking changes, holiday schedules. Keep residents informed without email fatigue.
Move-In / Move-Out
Onboarding checklists, utility transfer reminders, inspection scheduling. Smooth transitions.
Why Blasts beats email & SMS
| SMS | Blasts | ||
|---|---|---|---|
| Lands in dedicated inbox | ✗ Promo/spam risk | ✗ Mixed with personal texts | ✓ Own notification inbox |
| Rich formatting | ✓ HTML (if rendered) | ✗ 160 chars, plain text | ✓ Full HTML + attachments |
| File attachments | ✓ Often blocked | ✗ No | ✓ Lease PDFs, photos |
| Cost per message | Low but low visibility | $0.01–0.05 | Fraction of SMS |
| Opt-out churn | CAN-SPAM unsubscribes | 40%+ within 6 months | ✓ Consent-first, low churn |
| Read receipts | ✗ Unreliable | ✗ No | ✓ Webhook callbacks |
| Merge tags / personalization | ✓ With ESP | ✗ Manual | ✓ {{name}}, {{unit}}, etc. |
