Send letters of intent and keep your Gmail alive.
LOI Blaster is real estate LOI software that underwrites three offers on every listing — cash, seller finance, subject-to — then emails personalized letters of intent to listing agents from your own Gmail or Outlook, paced to look like a person sending, not a blast.
14-day trial · No credit card · $10/mo flat
Send bulk offers to listing agents — safely
The three things that break with guru spreadsheets and manual Gmail — handled before your first send.
🧮 Offer math you can check by hand
Three underwritten offers per property: discounted cash net of commission, a truly amortized seller finance payment, and a subject-to structure that pencils.
Real amortization — the same engine prices cash offers net of agent commission.
📮 Your inbox stays in good standing
LOI Blaster sends from your own Gmail or Microsoft inbox with OAuth, then paces every send so mail providers see a person, not a blast.
- Capped at 40 sends a day
- Randomized send delays
- Spintax on every email
⚠️ Underwater deals get held
If the loan balance leaves no room after costs, the deal never sends — no more embarrassing $0 offers in an agent's inbox.
🛡️ Compliance rides on every email
Every LOI carries an unsubscribe link, your mailing address, and a non-binding disclaimer. Subject-to letters add a due-on-sale disclosure. Automatically.
- CAN-SPAM by default
- STOP = auto-suppressed
- Due-on-sale disclosure
- Non-binding disclaimer
Automated offers on MLS listings, in three moves
Upload your listing CSV
Bring any export with an address, listing agent email, and asking price. LOI Blaster reads it in seconds and queues every property for underwriting.
Review three real offers
Each property gets a cash, seller finance, and subject-to offer with correct math — and underwater deals get flagged and held before anything sends.
Send at a human pace
LOIs go out from your own inbox — throttled, randomized, compliant. Agents reply straight to you, so every conversation starts where it should.
We have not published a single testimonial
LOI Blaster is early. Rather than invent quotes or a spam score we cannot show you, here is what you can check yourself: the math is on this page, the compliance lines are in every email, and the trial runs 14 days without a card.
Before you send your first LOI
Is a letter of intent binding in real estate?
No — an LOI signals interest and proposed terms; the purchase contract comes later. Every letter LOI Blaster sends includes a clear non-binding disclaimer, so agents and sellers know exactly what they're looking at.
How many cold emails can I send per day from Gmail without getting flagged?
We set the default at 40 sends per inbox per day because low, steady volume is what keeps a cold-sending mailbox out of trouble. It also adds randomized delays and warm-up pacing, and varies every message with spintax so no two emails are identical — duplicate blasts are what get accounts flagged.
How do you calculate a seller finance offer with a balloon payment?
Set your rate, term, and balloon year, and LOI Blaster amortizes the loan properly — a real monthly payment, not a guess — then shows the balloon balance due. Cash offers are priced by the same engine, net of agent commission.
Can you wholesale properties listed on the MLS?
Yes — many wholesalers make offers on on-market listings through the listing agent, sending 25–100 offers before one gets accepted. Real estate LOI software like LOI Blaster automates the volume part — correct numbers, safe pacing — from one CSV upload.
Your next deal is on a listing you haven't offered on.
