Letters vs. postcards for real estate direct mail

By the KonehMail team · Updated July 27, 2026

Both work — for different jobs. Letters feel personal and pull higher response; postcards are cheaper, seen instantly and ideal at scale. Here's how to choose.

Short version: Use letters when response per piece matters most — investor motivated-seller campaigns and personal outreach. Use postcards when cost-per-touch and visibility at scale matter — realtor farming and "just sold" updates. Many campaigns mix both.

Side-by-side

	Letters	Postcards
Feel	Personal, private (must be opened)	Instantly visible, casual
Response per piece	Typically higher	Typically lower
Cost per piece	Higher	Lower
Best for	Investor offers, long-tenure owners, sensitive segments (probate)	Farming, market updates, high volume
Personalization	Strong — name + address, handwritten-style, signature	Good — name + address, but public

When to send letters

Choose letters when the message is personal or the segment is sensitive. Investors chasing off-market deals generally lead with letters because a private, personal note — "I'd like to buy your property" — outperforms a public postcard. Probate and other delicate outreach should almost always be a letter.

When to send postcards

Choose postcards when you need frequency and reach at the lowest cost — the realtor farming default. They're seen without being opened, perfect for "just listed / just sold" and market snapshots, and cheap enough to mail a large farm repeatedly.

The hybrid play

Sophisticated senders mix formats: postcards for steady presence, letters for the moments that deserve a personal touch (a targeted seller, an anniversary of ownership, a direct offer). KonehMail supports both, each with its own cost tiers.

Frequently asked questions

Do letters or postcards work better for real estate?

Letters usually pull a higher response per piece and suit personal/investor outreach; postcards cost less and win at scale for realtor farming. The best choice depends on your goal.

Are postcards cheaper than letters?

Yes — postcards print and mail for less, which is why they dominate high-volume farming. KonehMail prices postcards on their own lower tiers.

Which should investors use?

Usually letters, because a personal, private note tends to convert better for off-market offers. Some investors test postcards for cost efficiency.

Can I mix letters and postcards?

Yes, and many top senders do — postcards for steady frequency, letters for high-value personal touches.
